All Units:

Can I send a unit back to the factory for service or repairs?

Absolutely! Anyone can send equipment to Rane for repair work, maintenance or testing, so long as a return authorization (RA) number is obtained before the item is sent. Units shipped from outside the U.S. may incur exorbitant import duty and landing charges so we suggest non-U.S. customers contact their appropriate International Distributor. We quote estimates for non-warranty work only by model number, at the time the RA is given. Once the equipment is received, it is worked on within a matter of days. No further estimates or quotations are given regarding work, unless the parts and labor will exceed the original dollar amount by 10 % or more.

If you want to request a return authorization (RA) number, provide all this information:

Your unit's serial number
Your and/or your companies full name
Your return shipping address
Your telephone number
Detailed description of the problem

With this information in hand you may then request an RA number from Service. Any requests not having complete information will not get an RA number. Units cannot be returned to the factory without return authorization numbers! When returning units for service, do not send the power supply or any other accessories unless instructed to do so. Also do not ship units in road cases, racks or any other containers. Use a standard issue, garden-variety corrugated walled cardboard box (see below) and have a professional packing agent handle transport and cartage. It will save your unit from shipping damage, which is not covered by warranty.

I need to modify a unit. Who do I talk to about this? And / or I have a modified unit and need to get it serviced, where can I take it? Also: I want to modify a unit for automotive use, how much do you charge for this service?

Modifications are against company policy, with very few exceptions. The ones we authorize and condone, as well as support are listed in the respective manuals or on our website. We do not support any automotive applications nor provide information to the do-it-yourself crowd for reasons of liability. Units which have been previously modified whether correctly or not, can be sent to the factory and returned to stock condition. We do not preserve unauthorized modifications or restore malfunctioning ones. This type of work needs to be sent to a custom shop or specialty technician. We do not have lists of this type of personnel nor do we support work in this area, (i.e. if it isn't stock, you're going to have a hard time getting support for the unit, unless you want it reverted back to original factory condition).

I need a schematic and / or manual for a unit, but don't see it on your website. What can I do?

Most products have documentation available on our site. The older units are listed in the Library section under Discontinued Products. If you don't see your unit listed, check there. Every letter in the model designation makes a difference, so be sure to view the exact same documentation for your particular unit, (i.e. don't use an MP 22z manual if you have an MP 22). The relevant documents are: Data Sheets for specifications and block diagrams, Manuals for operational details and instructions, and Schematics for internal wiring diagrams and circuitry references. Schematics for some units contain proprietary information which may not be completely divulged for confidentiality reasons.

My unit has one a line-lump power supply and the manual makes references about properly grounding the unit. How do I do so?

Units with external power supplies (the Rane RS 1 for example) do not get grounded through the power cord. Since no third prong exists on the AC power plug, you must connect a separate wire to the small silver screw on the rear of the unit -- look for the Rane warning tag -- and attach the other end of this wire to a good known earth ground. Some examples of this are: a steel AC conduit, cold water pipe, steel building girder, the center screw on an outlet or any other unpainted metal surface emanating from the foundation. Painted rack rails do not work, nor do rusty pieces of metal or those items which don't connect directly to the earth. When in doubt, have a licensed electrician verify the grounding. All too often our Technical Support Department receives calls about units damaged because they weren't properly grounded. Don't take chances, follow the directions completely.

I've got to send a piece back, but don't have the original box. How should I pack the item?

Very carefully seal the unit in a plastic bag, (a garbage bag works well) and then wrap the unit with large type bubble wrap. Make sure the item is covered on all sides by at least two inches of material per side. If you must use styrofoam peanuts, then be sure to compress the packing very tightly. We receive units every week which have received damage from insufficient packaging. This type of repair work is not covered by warranty and is typically very costly. Before sealing the carton, write your

full name
address
telephone number
equipment model number(s)
serial number(s)

on a piece of paper and enclose it with the product(s). It is also very wise to include any specific details relating to symptoms or problems you are having, with the item being serviced. This can same a great deal of time on the bench and that means lower total repair costs.

I need a part (fader, "telephone-type power supply", knob etc.) for my unit, but I can't get the dealer to order it. What do I do?

Customers can order parts directly from the factory by calling (425)-355-6000 between 8 and 5 Pacific time, weekdays. Alternately you can email your request to Customer Service. All orders or inquiries must have the serial number. Parts orders can only be taken for customers in the U.S. International correspondence should be directed to your International Distributor. Tip: When ordering parts, describe the piece exactly as it is on the product. (Example: Master Slide Pot; PCB Mount Headphone Jack; Phono 1 RCA Jacks.)

Where do I find the serial number on my unit? What does it look like?

Rane product serial numbers have taken on various forms over the 20 plus years we have been manufacturing units. In the very early days, units contained part of the model number within the serial number, and all of this type start at 1002. A period separates the model letters from the serial numerals, (Examples: AC3.2345 is an AC 23 from 1986, MP.1234 is an MP 24 from 1986 and ME.3333 is an ME 15 from 1987) These are found on a vinyl silver sticker, with black print about 1 1/2" wide and 3/8" tall. There may be as many as five digits after the model designation. The date code is a separate similar tag but only 1/2" wide by 3/16" tall. Numbering represents the manufacturing quarter of the year the piece was made, (Examples: 1-88 is January, February or March of 1988, 4-90 is October, November or December of 1990). Starting January of 1999, we changed to month codes. (Examples: Later smaller sticker 2-99 means February 1999 and 9-99, indicates September 1999). Silver tags were installed on either rear or side panels as matched pairs. On March 15, 1994 we changed to nonsensical serial numbers, dropping the model number from the nomenclature. The first of this type is serial 30001, (an AD 22 for those interested --- having a date code of 1-94). Finally, in October of 1999, we changed to a white thermal paper bar code sticker, listing both serial number and date code together. Isn't togetherness better? These are mounted on the side of the unit. Dimensions are 2 1/2" high by 1 1/2" wide. Each has (21) before the eight digit serial number (Example: (21) 00333333 [an ME 60 from August 2001]). Serial numbers are the bottom row of digits on the bar code decal. So for all those looking at used gear, be aware of what the date code can tell you. Also be specific and complete with regard to model numbers: an MP 24 is significantly different from an MP 24z. Likewise an AD 22 and AD 22d share very little in common with regard to circuitry. To the purchaser of used gear we say: "caveat emptor" (let the buyer beware).

Can I use more than one set of outputs on my unit? How much signal loss will occur if I do?

When multiple outputs are used, or a Y-cord is connected to drive parallel inputs, under the vast majority of situations no signal loss will occur. For the technically inquisitive, a minimum load impedance of 10 times the source is recommended. Most Rane outputs are 100 ohms per leg balanced, so net impedance limit is 1,000 ohms (or 1K). You may safely use all outputs at once, with the only concern being mixed mode wiring with balanced and unbalance combined can contribute to ground loops (i.e. low level hum in the system).

I saw a Rane unit recently with rubber knobs and different cosmetics. Can I change the knobs on my older unit to the new style?

Unfortunately no. When we updated the look of Rane products we changed to a different style knob (called a Flexi-fit) which will not fit the older units. Controls and artwork have changed and evolved. Like most anything change eventually happens and we thought it was time for a new look. Sorry to those who are confused or inconvenienced, but units with older knobs are still just as good as their newer counterparts.

I'm buying a unit in the U.S. take back home overseas and need to get it in 230 volt version, how do I do this?

This type of purchase is called a gray market transaction. Warranty on Rane products only applies in the country of purchase and U.S. models only ship with 120 VAC power supplies. Units taken out of the U.S. do not have warranties in the destination country and some distributors may not offer any parts or service support. This is their option. Rane discourages gray market purchases and highly recommends that customers buy Rane items in their home territory, due to a multitude of reasons. Be forewarned that saving a few bucks on the purchase price is easily wasted the first time service is needed. Certain Rane units are Factory Service Only and since the distributor is the only one who can repair them (or send them back to the factory for repairs) gray market units come with substantial limitations. Support your local agents; buy locally.

Does the unit come with Euroblock connectors and / or Does it come with the remote power supply? (Are all the accessories included?)

Yes. All Rane products using Euroblock connectors (a k a Phoenix plugs) come with the required connectors to hook the unit up. The same holds true for any Rane unit which requires an external power supply; it is included with the product. Audio cabling is the only element not included with a new unit. Only units which use an RS 232 cable may require and additional purchase. We ship an 18" cable for "jumping" multiple units, but may be shorter than practical for connecting the computer.

What is the maximum BTU / Hour produced by model [ insert model here ]?

To calculate maximum BTU / Hour, multiply the input power rating in watts on the rear panel of the unit (or on the external power supply, [i.e RS 1]) by 3.41. Example: RPM 88 is rated at 55 watts AC, therefore we expect a maximum of 187.55 BTU / Hour.

How hot / cold / wet / high can I make my unit?

See our Environmental Specifications.

AC 22 / AC 22B:

Can the unit be modified for constant directivity horn equalization?

This is a simple modification that requires installing a specific capacitor on the pre-drilled circuit board, determined by your CD horn rolloff point. Download this PDF note.

I need to move the delay circuit, but I cannot find the jumpers listed?

The current version AC series crossovers use SMT (surface mount technology) devices and therefor we had to eliminate the delay transplant modifications. All possible options are here: Crossover Modifications. Note: not all versions can accept changes. Some do not offer any configurable options.

AC 23 / AC 23B:

How can I get my AC 23 crossover point below 190 Hz in 2-way stereo mode?

The AC 23 is not designed for 2-way operation below 190 Hz. You can "fake it" by using a summing Y-cable (check out Why Not Wye?) on the mids and highs in 3-Way mode. This allows you to use the Low/Mid (70 - 1 khz) filter for the lows. If you're really adventurous, you can modify the filter limits. Download this PDF note on Crossover Modifications.

I need to move the delay circuits but my unit doesn't match the layout in the manual.

Earlier AC series units do not have all the flexibility of later ones. Thus not all features exist in every variant. Additionally the current versions using SMT devices do not offer the delay transplant option. It is not viable within the design architecture presently utilized.

My AC 23 doesn't have the 2-way / 3-way switches on the rear panel, how can I run it in 2-way mode?

Earlier AC 23 units did not offer 2-way mode operation. They run 3-way stereo, 4-way mono and 5-way mono only. Externally combining a pair of signals -- mids and highs or mids and lows -- provides a means to achieve 2-way functionality. As above, the summing Y-cable is used to mix two signals together, (see Why Not Wye?).

My AC 23 is in 3-way mode but there are no highs in channel 2 and no mids in channel 1.

The AC 23 has switching jacks and must have connectors plugged into every jack (as shown in the AC 23 manual) for the configuration being used. This is the most common call we get. Try plugging connectors into all of the outputs, then verify their operation.

AP 13:

What is the difference between the EFFECTS SEND / RETURN and INSERT connections?

The SEND / RETURN connections provide for up to a 50:50 mix of the effect signal and the dry audio, but the INSERT points interrupt the signal path such that the entire audio path us routed through the external processor. Typically delay, reverb, chorus and other similar units are connected to the EFFECTS SEND / RETURN points. The INSERT jacks are better suited for compressor / limiters, aural enhancers and equalizers.

Can I use the XLR and 1/4" outputs at the same time.

Yes. In fact you can use all four outputs at once. Two will yield line level and the others provide mic level. This is practical for live sound situations where multiple feeds and connections are needed. Some users run the 1/4" output(s) to their stage amps and the XLR is fed to the house PA console.

I have preamp in my guitar already. Can I connect my guitar to the AP 13 directly?

Sure. The onboard guitar preamp isn't usually necessary, but the AP 13 will work fine with most all varieties. Check to see if you need phantom power from the AP 13 though. This setting can be very important to maximizing performance with a second preamp.

I've seen the SP 13 and want to modify my AP 13 for dual piezo inputs. How can I do this?

Rane has an exclusive distribution agreement with Chapman. We cannot disclose any information about circuitry changes, modifications nor other proprietary details. Those who play a Chapman Stick are better off getting an SP 13.

I want to connect two different mono instruments to the AP 13 (Banjo / Guitar, Fiddle / Bass, Flute / Mandolin etc.) How can I do so?

Treat both input channels --- Piezo and Mic --- as separate paths (think of it like two channels on your mixing console) and connect using a common insert-cable. This type of interconnect looks like a Y-cord, but has a stereo 1/4" TRS plug at its junction. One instrument gets connected to one of the 1/4" plugs and the remaining plug hooks up the other instrument. Insert-cables (a k a send-return cables) can be purchased at most music retailers who carry PA equipment.

I hooked up a volume pedal and now the microphone doesn't work. What's wrong?

Volume pedals must be connected at the INSERT points on the AP 13. You cannot connect and instrument to a volume pedal and then plug the pedal into the AP 13, since the pedal will not pass phantom power and the impedance mismatch may also cause problems.

What microphones work with the AP 13?

AVA 22d:

I hooked up the AVA 22d but don't get unity gain through the equipment.

If you are running the product in certain types of broadcast environments you may need to add 600 ohm termination resistor(s). If the device feeding the AVA 22’s input has a 600 ohm output impendance, and the load on the AVA 22’s output is also 600 ohms (i.e., you’re interfacing the AVA with video gear’s audio I/O), changing the output resistors R70 & R69 to 300 ohms allows the same level to be passed while the AVA 22 is bypassed or processing the audio signal. Read the 600 Ohm User Information note in the manual for additional details.

BB 22 / BB 44x:

Will the unit work in reverse (i.e. is it bi-directional)?

Yes. The products do not have a required signal flow. Simply use the inputs as outputs and vice versa. Note: The OPTION 88 works exactly the same as the BB 44x, since the same assembly is used.

CP 52 / 64 / 52S / 64S:

Are the CP 62 remotes compatible with the CP 64?

No. The CP R1 and CP R2 only work with the CP 62. The proper remotes for the CP 64 are the PR 2 for paging, and the ZR 1 for source and level control.

How can I hook a fire alarm control relay to the unit for complete muting?

Connect a normally closed relay across the Paging Inputs (plus [+] and minus [-]) so they are shorted together. When an alarm condition exists and the coil becomes energized, the contacts open and the short is removed. The Paging Input Detect Threshold must be adjusted such that the noise floor is sufficient to trigger a paging condition and enable ducking, (i.e. set the detector just shy of maximum sensitivity --- fully counter clockwise --- so shorted turns off the green LEDs and open causes them to illuminate). On the CP 64, make sure to assign Paging Priority correctly using the internal selector switch (S12 Manual Page 4). Front panel Ducker Depth control is adjusted to fully counter clockwise so no program material is audible during an alarm condition.

What are the EXPAND OUTPUT connections for?

These fixed line level outputs are for driving other systems or "stacking" CP 64s, CP 52s and/or CP 31s together for larger applications. The signal may consist of paging only, program only or a copy of the zone signal. This output can be used for music on hold as well as zones not needing level adjustment (i.e. rest rooms, entryways and similar areas).

What type of wire can I use to connect the remotes?

For runs up to 200 feet any five conductor wire, 22 gauge or larger, will suffice. Use shielded wire for distances greater than 200 feet.

Can Zone 1 of the CP 64 operate in Mono mode?

Yes. The CP 64 has a Zone 1 Mono Switch located internally, directly in front of the Priority Assign switch.

When Zone 1 of the CP 64 is in Mono mode, which outputs LEFT or RIGHT should I use?

Either set will provide a summed LEFT plus RIGHT mono signal. You can use both LEFT and RIGHT outputs simultaneously when needed, (like when you want to run two channels on a power amplifier without connecting a Y-cord.)

When the Priority Signal finishes playing, it takes too long for the music to fade back in. Can I adjust this?

Yes. The internal Program Priority Release Time control, located near the Line 2 and Line 3 RCA input connectors, can be rotated to change the interval from five to twenty seconds. Clockwise rotation increases the release time interval.

I just want a remote volume control, not source selection. Is there a way to do this?

All selection and level is done either on the front panel or at the remote; never both locations. Connecting just a VR 1 to the CP 64 or 52 remote control terminals will allow level adjustment. However without a source selector the unit will default to source one. If the PRIORITY / L4 INPUT automatic switching is enabled, then the unit will select the L4 signal when present and L1 at any other time. Thus if only a jukebox (P/L4) and other line source (L1) are used, the remote volume control will work just fine. Refer to the CP 52 and CP 64 documentation as well as the ZR 1 literature for clarification.

Is there a way to bypass the equalizer in the unit?

Unfortunately no. However we do offer the SCP 1 and 2 (CP 52 and CP 64 respectively) security covers for covering just the equalizer slide controls.

I just installed a unit and don't get audio. Or I hooked up the ZR 1 source remote but can't get any audio. What happened?

First check all the wire connections at both ends of the remote. All five wires must be connected for proper operation. Also make sure you didn't "flip" the wiring at one end of the cable. It happens very frequently. Also note that once the front panel RMT button is pressed "in" both the PROGRAM SELECT and LEVEL functions only work at the remote. These two front panel controls are disabled when the CP 52/64 RMT switch is engaged. For testing purposes, push the RMT switch and make sure it's in the "out" position. Then, re-test all functions of the CP unit. If all works fine now then the problem lies in the remote or wiring to it.

I can't get either paging microphone to work. What am I doing wrong?

First check all the wire connections at both ends of the mic cable. Next be sure to set the PAGING INPUT MIC/LINE switches correctly. Facing the rear panel, MIC position is to the left. Once you have the setting correct turn up --- clockwise --- the PAGING TRIM control and see if you can light the PAGING OVERLOAD indicator. If it illuminates, you're getting hot enough audio into the paging preamplifier. Last practical field check is to be sure the front-panel PAGE ZONE ASSIGN switches are set correctly. If all this checks out, it's time to re-read the manual and follow the Recommended Calibration Procedure.

CP 62 (discontinued):

Which remotes can I use with this unit and are they still available?

No, both the Paging Assign Remote CP R1 and the Source / Level Remote CP R2 are discontinued and remaining stock has been sold. These are the only remotes that are compatible with the discontinued CP 62. Parts to repair existing remotes can be ordered through Customer Service.
IMPORTANT NOTE: The CP 62 is the only Rane remote powered model produced which must use the RS 2 power supply.

DA 216A / 216S:

Is it possible to get mic-level signals from the outputs?

Not without adding external pads. The DA 216a is a distribution amplifier supplying line-level audio so reducing the signal to mic-level requires an outboard attenuator of some type.

Where's unity gain on the DA 216a?

With "Line" & "0" dB of gain selected on the rear, the front panel Input gain is unity at full clockwise. There is 10 dB of gain between this point and the output, so with the inputs set in this manner, the output trims are unity at 12:00 noon.

EMPATH:

I noticed the EMPATH uses P & G faders, but the TTM 56 has your no-contact magnetic fader. Why isn't the 'mag fader used in the EMPATH? Can I put 'mag faders in my EMPATH?

The EMPATH is an all around touring, recording performance and club mixer. It covers the vast majority of today's DJ uses. Our TTM 56 is solely aimed at performance work (scratch and similar uses) which dictated the 'mag fader be utilized. Additionally when properly maintained, the P & G faders will last a very long time. Neither type of fader --- P & G nor 'mag fader --- can be retrofitted into any other mixers. They only work in the model we designed for them.

I bought an EMPATH before the black and gray was available; can I get my mixer updated to the newer color or trade my mixer in?

Rane currently does not offer any means to change colors nor do we have a trade-in / trade-up program. All changes, trade-ins and other similar sales transactions are solely at the discretion of the dealer. This is similar to changing the color of a car you bought. The trade-in amount may be considerably less than you paid for the product.

HC 6 / 6S:

When I use the direct inputs I lose the signal from my master, can I get both through the unit simultaneously at the same output?

No. You you need an external mixer to be able to hear both. Each input is either a direct headphone amp, or fed from the masters, but not a mix of the two signals. You can use any number of direct inputs and the remaining inputs will still receive signal from the master section.

How can I convert the DIRECT INPUTS to balanced mono?

A technician needs to remove to internal jumpers per input and solder two new jumpers into alternate locations silk-screened on the circuit board next to the DIRECT INPUT jacks. This change is fully documented in the Operator's Manual and requires familiarity with modern PCB servicing techniques.

How loud is the HC 6?

It can be extremely loud, but it depends on your headphone impedance and sensitivity. For a list of the most popular headphones, and the SPL expected from each, See Understanding Headphone Power Requirements.

MA 3 and MA 6S:

Can I feed all channels the same signal just by connecting to one of the channels?

Nope! You can use jumpers to connect all input channel connectors (plus and minus required, shield is discretionary). For the MA 6S, in normal (unbridged) mode, all channels are independent. In bridged mode, adjacent channels are paired for master/slave operation. The pairing for bridged mode is 1 & 2, 3 & 4, 5 & 6.

Can I run the unit below 4 ohms load?

Well, probably. The MA 6S will not be damaged but you will obtain much less power output, and an extremely hot amplifier. To protect itself the MA 6S will current limit to the best of its ability. The MA 3 will current limit also and its fan must be set to high speed. Be forewarned that running below rated impedance voids the warranty and may damage the amplifier channels as well as power supply.

Which jumpers do I cut when installing a TF 407 or TF 410 transformer (for the MA 3)?

You MUST cut wires W6, W8 and W13 for channels one, two and three respectively. Additionally you may wish to cut W9, W10 and W14 to break the minus connection from primary to secondary. See the TF 407, TF 410 Manual for installation instructions.

I can't tell which terminals to connect to the amp on the 70.7 transformer (models TF 170 and TF 370 for the MA 6S).

Looking at the top of the transformer with all five terminals facing you and the three secondary terminals pointing NORTH, the upper left and lower right terminals are the MINUS (-) connections. The upper right and lower left are the PLUS (+) connections. The one remaining center terminal is the 25 Volt output connection --- applies to TF 170 and TF 370 only. Example: All four outermost terminals connected yields a typical 70.7 Volt output from an 8 ohm amplifier channel. Here are the TF 110, TF 170 and TF 370 technical details and mounting instructions.

What is the typical current draw?

When running all channels into 4 ohm loads the unit will usually operate at around 1400 watts AC draw. This of course assumes adequate line voltage. Sag in the AC source may increase the current draw and cause the amperage to climb. An MA 3 typically draws less than 250 watts all channels loaded at 4 ohms.

My system seems a bit noisy running through the amp. Is there something wrong with the equipment?

Not likely. The most common misconception is that amplifiers must be turned up all the way to achieve maximum output. This is simply not the case. Most amplifiers will reach full output (and clip accordingly) with sensitivity controls set between 12 and 2 o'clock when fed a + 4 dBu signal. Try turning down your amp(s) and verifying the clipping point. This can make a drastic improvement in reduction of noise. See Setting Sound System Level Controls.

I'm running the amp through 70.7 transformers and the red lights flash whenever moderate amounts of bass are present. Am I doing something wrong?

Check to be sure the internal 80 Hz high-pass filter is engaged on any channel driving an output transformer. Due to their design some transformers tend to saturate at lower frequencies and this can cause excess current draw problems for the amplifier. You probably won't damage the amp, but best performance will be obtained by switching on the high-pass filters. MA 6S channels may blow one or both of the internal 5 amp fuses, when driving transformer loads without using a high-pass filter.

I think something is wrong with my fan.

Check for a gecko.

ME 15B / 15S / 30B / 30S:

What's the difference between the "B" version and "non-B" type?

The earlier units only had 1/4" inputs and outputs. Inputs are fully balanced, outputs are single-ended (some say "quasi-balanced") auto balancee/unbalanced. Ability to drive longer cables is less and high frequency rolloff can be a concern due to cable capacitance. Around 1994 we updated the design and changed to the "B" designation. These units have fully balanced inputs and outputs, both XLR and 1/4" TRS connections being utilized. Functionally the units are virtually identical. With the exception of much enhanced grounding, the older units possess almost the same sonic quality. The "S" versions have a new universal power supply, operating from 100-240 VAC (true for all Rane "S" models).

Can I use both the XLR and 1/4" outputs at the same time?

Yes. Both sets of output connections may be used simultaneously. However only one input may be used at a time. Also remember if you run unbalanced 1/4" with a balanced XLR you may have ground loop problems.

ME 60 / 60S:

If I use the RCA inputs with the XLR outputs does this make my system balanced?

Any unbalanced wiring in your system will unbalance the entire system, so you should try to run balanced everywhere possible. All subsequent wiring from the ME 60 downstream will be balanced in this scenario. We suggest reading Sound System Interconnection. If you feed a balanced input from an unbalanced output you can still retain the benefits of balanced wiring, but you have to modify your cables.

MLM 82 / 82A / 82S:

How I can assign the XLR microphone signals to left or right?

There is no pan control on the unit so this can only be accomplished with a semi-permanent modification. Removing the appropriate 4.02k ohm resistor from the board will prevent the signal from appearing on that bus output. (example: Removing R51 prevents the channel 1 signal from appearing on the left output connector.) The MLM 82a addresses this through the use of assign switches.

MM 8x/z:

Is there any way to run the headphones in mono mode like on the MP 24/x/z and MP 22/x/z?

Unfortunately there is no way to obtain a mono headphone signal from this mixer. The use of a single cup mono headphone is not advised either as it can cause distortion in the headphone amplifier. (See below for system mono option.)

What type of cables do I need to connect a processor to the PROGRAM LOOP?

These jacks are unbalanced TIP = send, RING = return INSERT jacks. The cable used is called an "insert cable" and resembles a Y-cord with two unbalanced TS plugs joined to a single TRS plug also configured unbalanced. This type of cable may be obtained off-the-shelf at many pro audio dealers.

Can the mixer outputs be run in mono mode?

Yes. By building a summing Y-cable (check out Why Not Wye) and connecting it to the MAIN OUTPUTS a mono signal may be obtained.

MP 2016 / XP 2016 / a:

I don't see any way to hear CUE and PROGRAM (MASTER) signals at the same time. Can this be done?

No the MP 2016 headphone and booth switching configurations do not provide simultaneous multiple signal monitoring. You can however send one signal to the BOOTH output and a different one to the HEADPHONE section.

Can I get a longer cable for the XP 2016 expander / equalizer unit? I want to mount them next to each other.

Yes. The longer version cable is 25" which provides enough length to mount the MP/XP combination side by side. It can be ordered directly from the Parts Department using part number 11537, (Standard 10" long cable is supplied with XP 2016. It's number is 10897.)

I can't get my BOOTH OUTPUT to play loud enough. Is something wrong?

Not likely. First easy way to test the mixer is flip the BOOTH CUE / MASTER toggle switch, up to the CUE position. If the audio from the BOOTH OUTPUT is now much louder then the mixer is fine and you need to run your levels higher. Make sure to set the INPUT GAIN controls so that the SIG / OL LEDs flash green. Also make sure that the MIX LEVEL controls are set to at least 3 o'clock. If the controls are set too low, then the BOOTH OUTPUT and MASTER OUTPUT signals will be weaker and the SIGNAL to NOISE ratio will suffer.

MP 22/x/z:

The crossfader on my mixer bleeds audio from one bus when I have it set all the way over to the opposite bus. Is there something wrong with the fader or the mixer?

Probably not. If you move the fader to one side and turn up the other input fader, a little sound leads one to think there is a defect in the unit. What this is caused by is a combination of maladjustment and improper gain structure. Overdriving the input of the mixer will compound this symptom. Don't run the output of a source wide open unless you actually need the level. Gain structure adjustment at the input is very critical for best signal to noise performance. Another concern is running the INPUT faders too low then compensating by setting the MASTER fader too high so you have enough signal to drive the system. Turn the INPUT fader up and the MASTER down slightly. This helps 99% of the "bleeding" of "leaking" crossfader complaints we get here at the factory, just operator error due to incorrect gain structure.

Should I use a cleaner or spray anything into the slide controls?

Absolutely! We use very high quality (high cost) slide pots and like a fine race car, maintenance is critical. If you keep the pot clean and lubricated it will last many years. If you neglect them then try to restore them with a generic cleaner you will just have to replace them. Don't just use any "contact cleaner", see our Detailed Slide Pot Care Procedure.

What are the differences between the MP 22, MP 22x and the MP 22z?

The MP 22x and z have the new active VCA crossfader circuitry used in all current Rane DJ mixers. The VCA circuit design reduces crossfader travel noise, increases the life span of the slide pot and dramatically lessens bleedthrough. Also, the MP 22x/z have balanced 1/4" TRS outputs instead of the two sets of unbalanced RCA connections on the MP 22. Functionally the two units are almost identical. The active VCA crossfader and its circuitry cannot be retrofitted to the MP 22, and a MP 22x cannot be converted to a MP 22z. See Rane Club Mixer Comparisons, noting the similarities and differences between the MP 22x and z, the MP 24x and z, and the MM 8x and z. Additionally the new z model has continuously variable crossfader contour adjustment allowing for blending and performance style fading. (This control also allows the crossfader to operate with no "dip in the middle.")

I'm using the mixer in my home and I have a lot of "bleed" through the faders. What's wrong?

Nothing really. The mixer is putting out a +4 dBu (1.23 Vrms) signal which is 12 dB stronger than the normal home stereo level of - 10 dBV (0.316 Vrms). Since the mixer's signal is so much louder, the residual "noise" (the signal you don't want to hear) is more audible. Try turning down the level controls on your amplifier (or receiver.)

Can the mixer outputs be run in mono mode?

Yes. By building a summing Y-cable (check out Why Not Wye) and connecting it to the MAIN OUTPUTS a mono signal may be obtained.

MP 24/x/z:

I need a new faceplate for my older MP 24. How can I order one?

The original version MP 24, built from 1986 to about mid-1994 has a power switch on the front panel and is equipped with a three-prong grounded AC cord, (as opposed to all later MP 24s which use the RS 1 external power supply, with the "telephone" connector.) Front panels for this version are no longer available and newer front panels do not fit. When the MP 24 was updated to RS 1 external power, components had to be relocated and so the front panel mounting points changed. Due to this fact later faceplates will not fit the original MP 24. We're sorry for this inconvenience, but unfortunately this is unavoidable.

I can't get the AUX MIC to turn off all the way even with the control at zero.

This is not supposed to be a level for turning off the mic, but instead it is a TRIM for adjusting the gain of the input stage. The MIC ENGAGE switch is for turning the mics off.

Can I run the BALANCED and the UNBALANCED outputs to two different systems at the same time?

Yes. Just be aware that if you mix unbalanced with balanced you invite hum and buzz into your system.

I just got a brand new MP 24x/z and the PHONO 3 inputs are really low in volume no matter what input fader I use. What's wrong?

See the Operators Manual, specifically the section on switching the PHONO 3 INTERNAL PROGRAM JUMPERS. These two jumpers need to be set for the PHONO position. They are shipped in the FLAT position which allows for line level input.

Can I run an unbalanced line (like an RCA plug) into LINE 2?

Sure. Just get the appropriate adapter or cable to plug into the 1/4" TRS jacks and use the input like any other line input.

What is the EQ range switch on the rear of the mixer for?

This switch changes the amount of boost and cut the equalizer provides. In the out position, the equalizer controls allow plus or minus eight dB of boost and cut. When the switch is set to the in position, the range is plus or minus four dB of boost and cut. When a system is likely to distort, if the DJ "pumps up the bass," setting this switch to the "in" position (±4) can help to prevent overloading the system.

What are the differences between the MP 24x and the new MP 24z?

The only difference between the units is the fact that the MP 24z uses our new monorail crossfader and its VCA circuit design eliminates the crossfader's "dip in the middle." Using a VCA crossfader circuit, increases the life span of the slide pot and dramatically lessens bleedthrough. Additionally this crossfader is identical to those used in the MP 22z and MM 8z, and all three mixers have an optional short throw fader available.

Can I get retrofit the new style field replaceable crossfader into my older MP 24?

This is not possible due to major internal differences within the units.

Is it possible to connect an XLR microphone to the AUX MIC input?

Yes. You will need an XLR to 1/4" balanced to unbalanced transformer. Cables are available with this device built-in.

Why can't I record my microphone when I'm making tapes, with my deck connected to the TAPE OUTS?

You need to change the settings for the jumpers J25 and J26. These send the microphone signal to the TAPE OUTS. (Older MP 24s [those with power switches] don't have these jumpers.)

What is the LOOP ENGAGE SWITCH for?

It turns on any processing connected to the SWITCHABLE LOOP. If nothing is connected to those jacks, the switch won't make any audible change.

How may volts is output by the MP 24/x/z?

The unit has a maximum output level of +22 dBu, which is about 10 volts rms. (-10 dbV=0.316, 0 dBu=0.775, +4 dBu=1.23, +22 dBu=9.75 all in volts rms.)

Why doesn't my newer MP 24/x/z have a power switch? My older one does.

We removed the power switch from the MP 24 when we converted to Remote AC Power. Since the unit no longer needed the power switch and customers had asked us to delete the control we removed it. You can leave an externally powered MP 24 plugged in and turned on 24 hours a day when necessary.

All DJ Mixers:

When I use the 1/4" balanced outputs, no signal comes out, but the RCA jacks work fine. Why?

Typically this is caused by incorrect adapters being used. There is a 1/4" to RCA adapter available which looks balanced at the 1/4" end, but it's not. There is no such thing as a balanced 1/4" to RCA adapter. Those which have two insulators (look for two black stripes) and resemble a common stereo headphone plug are just that: a stereo plug. It's not balanced and won't work in the 1/4" output jacks. The correct adapter is an unbalanced (i.e. "mono") 1/4" plug to RCA jack. This is not the best way to hookup the mixer, but usually can be done without damage. If no adapter is being used, check the wiring at the other end. A balanced 1/4" cable should connect to an XLR plug as follows: Tip = Pin 2, Ring = Pin 3 and Sleeve = Pin 1. Connect all three wires and do not short any of them together at either end.

When I use a single cup headphone the sound is distorted. What's wrong?

Single cup headphone devices don't work with these mixers and may cause damage to the electronics in the unit.

What crossfaders can I install in my unit?

There are a few exceptions, but for the most part only one type of crossfader can be installed in any Rane mixer. Click here to see what the part numbers are: Crossfader Replacement Chart. Plug-in crossfader assemblies are only available for "x" and "z" version mixers. All others --- even those which have plug-in modules (MP 22 and MP 24) require soldering when replacing the crossfader. This is due to discontinuation of older parts.

Can the active VCA crossfader be retrofitted into a non "x" or non "z" version mixer?

Unfortunately not. There is significantly different circuitry in the mixer that prevents this retrofit.

Can the monorail "performance fader" be retrofitted into a non "z" version mixer?

Sorry but no. There are too many mechanical issues that prevent this retrofit.

Should I use a cleaner on the slide controls?

MS 1/a/b:

How can I rack mount the unit?

You may use any one rack space tray. This allows three MS 1a preamps to sit in a 19" space.

How do I wire the output for unbalanced use?

Since this unit uses a cross-coupled output, it is imperative that pin 3 be grounded to pin 1 and the audio positive connected to pin 2. It is also very important to make sure the unit is earth grounded using a separate wire connected to the chassis ground screw near the red power connector. See Sound System Interconnection for further details. Not having an earth ground connection to the chassis is the number one cause of failure

PE 17:

What does serial/parallel filter design mean?

It's very useful because it means that if you set two series connected filters at the same frequency (filters # 1 and 3 or 2 and 4) the boost or cut value of each filter sums. Simply stated you get up to plus or minus 24 dB of adjustment through the use of a pair of filters.

PI 14:

Where do I connect the PI 14 in my signal path?

The PI 14 will work wonderfully well anywhere in the signal chain as long as the ECSTASY level is not exceeded. We frequently hear of people using too much ecstasy and having big problems.

RA 27 / RE 14 / RE 27 (all discontinued):

Can I extend the cable for the mic?

Yes, but it may cause more hum to be picked up and thereby causing a false reading @ 60 and 120 Hz.

How loud should my system be set when I use the analyzer?

Basically you want the PA set for a normal "playing" volume. Don't get ridiculously loud but have the system at a level loud enough to overcome any background noise.

I need a replacement mic for my unit. or My microphone stopped working can I get it repaired?

The microphone for the RA 27, RE 14 and RE 27 is not a serviceable item. Although delicate and very accurate it is quite affordable to replace in the event yours is broken or missing. Just contact the Parts Department and tell them you wish to order a replacement analyzer microphone, (a k a MIC 1; no fancy part number needed here.)

Can I use a different microphone with the unit?

The MIC 1 is the only microphone we certify to operate correctly with the RA 27, RE 14 / 27 models. Using any other device may damage the analyzer, measuring device or both. The one known measurement microphone witnessed compatible with the RA / RE series retails for over $ 500.oo, thus it is wiser to purchase an original Rane microphone.

RaneWare

Whenever I open a window on a window the program crashes. What's happening?
Does RaneWare run under Windows XP?

RaneWare is a 16-bit program written to run on Windows 95, 98SE and earlier OS's like Windows 3.1, though in some instances will not work on Windows NT, and most instances 2000, ME and XP are inconsistent. The crashing is caused by the WOW32.DLL in later OS versions not being compatible with RaneWare and other file issues. Officially we support only the Windows 98SE and earlier operating systems. The only solution is to run the earlier version: Windows 95 or 98SE. Other OS's might work but we can't guarantee or support all the variables.

Windows NT 4.0 seems fine, but you cannot print consistently with version 2.3. RaneWare version 2.2 does seem to print correctly under NT 4.0.

RaneWare does not work in any modes under Windows 2000. It "crashes and burns" if not immediately after startup, then soon after. WOW32.DLL is the most common problem witnessed under Windows 2000.

Under Windows ME, it seems "OK" in offline mode and fairly inconsistent in online (i.e. hardware connected) mode.

Under Windows XP, offline mode seems "OK" but online mode is anybody's guess. It varies wildly depending on if it's a desktop versus laptop machine and also what type of ports are on the unit. Machines sporting USB ports running XP are far more likely to experience issues when polling for our hardware.

I don't want to use a password. Can the password function be bypassed?

Yes. Entering one press of the spacebar as the password effectively bypasses the password. (When you are prompted for the password simply press "enter")

How many conductors are required to interconnect units to the COM port on the computer?

The RS 232 cable for the unit uses two conductors and a shield. Pins two and three are the data with pin five being the shield.

I lost the password for the RaneWare. Now what do I do?

There is a file that contains the information which will have to be deleted. Once it's gone all the Site Control Panel names will be lost. This file name can be obtained by contacting us by fax, phone or email. [We won't post the name here just in case someone has a warped sense of humor.]

I'm running RaneWare in Windows 95/98 and got stuck in the Site Control Panel. How do I get out of it?

Right mouse click on the Title Bar (the top of the window where it says Site Control Panel) and select Device Edit. You will then need to enter the password, (stock is "please".) In case your mouse isn't working you can get to the Device Edit option by pressing Alt. and the Spacebar together. This will give the drop-down options of: Device Edit or Exit.

RPE 228d (discontinued)

What is the difference between this model and the previous RPE 228?

The original RPE 228 used digital control of analog filters. The later RPE 228d filters are completely digital, utilizing some of the finest DSP technology available. This results in a much quieter and better performing unit. Both are discontinued. Use the RPM 2, the best solution yet.

RPM 26v (discontinued):

I've connected and set up the RPM 26v as the manual instructs, but the unit seems very noisy. What can be done to correct this symptom?

To obtain the best signal to noise performance from the unit it is necessary to adjust the INPUT TRIM carefully. By opening the INPUT TRIM window in RaneWare the level ladders may be viewed. Adjust the trim so the A/D (dBFS) indicator just occasionally lights yellow. Alternately the Sig A/D indicator (adjacent box in RaneWare) may be viewed for level indication.

The Output 2 LED is flashing. How do I reset the unit?

Unplug the AC power cord from the outlet. Now hold the rear panel Default button in (you'll need a pencil, paper clip or similar long slender object) and reconnect the AC power cord to the outlet. Keep holding the button in, until the Output LEDs flash the "Knight Rider" pattern (from the outside LEDs towards the center), indicating the unit has been reset. If the unit will not reset with this method contact the factory for further information.

Is there a way to overwrite the DSP routines to customize the configurations?

Currently we do not provide the code to allow custom DSP implementations. We do provide the code to allow Memory recall. See the RW 232 Device Control Language PDF file.

RS 1/RS 2 (RS 2 for CP 62 only):

Why do you use "wall warts?"

We don't. The common term wall wart refers to power supplies that include the AC plug prongs in the housing with the transformer. This causes the unit to be take up unnecessary space on an outlet strip and prevents secure mounting in a rack. Our remote power supply has a 6' cord for each high and low voltage connection in addition to mounting tabs built into the case. Other benefits for using external transformer power supplies are numerous. Some important reasons are: UL and other agency certification on one power supply keeps prices down. External transformers result in lower hum and noise figures. Service replacement and multiple unit powering is a much simpler issue to deal with. Having an external supply with a thermal circuit breaker (Rane does not use glass fuses) allows the supply to shut off during a fault and come back on when the problem is solved thereby avoiding the "blown fuse" symptom. See External Power Supplies.

* SURVIVAL TIP: To keep from breaking off the locking tab on the modular plug you can plug the RS 1 (or 2) into a six wire coupler and install a short six wire jumper between the coupler and the product needing power. This way you don't wear out the RS 1 (or 2) supply connector and instead the jumper takes all the (ab)use.

The locking tab on the clear plastic plug broke off; now the connector falls out of the red jack. What can I do?

First thing to do is buy a backup power supply. You should carry a spare RS 1 if yours is a mobile application. Power spikes can damage even the best surge protectors and connected equipment, so it is imperative to have alternate equipment ready. U.S. customers may order spare RS 1 power supplies directly from our Accessory Store at Rane.com. Alternately if you have the extra time, you may call for a return authorization and send the item back to have a replacement plug installed (again this applies only to U.S. customers). The minimal fee is for shipping and handling. The part itself (a six-wire RJ-12 plug) is provided no charge. Note that some electronics retailers carry crimping tools for RJ series connectors and replacing the plug is very simple. Cost of the tool can run from less than 20 bucks all the way up to over a hundred depending on the type. You must install a six-wire (RJ-12) plug on the RS 1 for correct operation. And for those wondering: No, replacing the plug after breaking off its locking-tab is not considered a warranty repair, nor is it a manufacturing defect. This is caused by being too rough on the plug assembly during handing (winding and unwinding cables).

My unit says RS 2 on the rear but it came with an RS 1. Will the RS 1 work with the unit?

Absolutely! All Rane products, with the exception of the CP 62, will operate perfectly on the RS 1. This includes older units that originally shipped with an RS 2. The discontinued CP 62 is the only Rane product which required the RS 2.

Can I run multiple units from a single RS 1 or RS 2?

Absolutely not, without grounding consequences! In addition to needing a 6-wire modular wye connection, the transformer center tap has to be lifted on all but one of the pieces being powered. And with all that nuisance you are restricted to using only balanced wiring. The better choice is to use individual power supplies for each product.

SAC 22 / SAC 23 / MX 22 / MX 23:

How are these units different from the AC 22 and AC 23?

The MX series crossovers are stereo units. One control affects both channels left and right. The AC series units are dual mono. This means channel one can be set differently from channel two. Additionally, the AC series units provide driver alignment delay controls and optional CD horn compensation.

Why do these crossovers only have XLR connectors?

After conducting extensive research, we found that since space forced us to make a choice between XLR and 1/4" connectors, our customers preferred a locking, balanced professional audio standard connector.

Can I use just the Highs and Lows to run the SAC 23 in 2-way mode?

Yes you can, if both frequency selectors are set at the same crossover point. The high frequency output will be 6 dB lower in level than the low frequency output. It is much better to use the SAC 22 or AC 22B for a 2-way application.

SM 26 /26B / 26S:

Are the inputs and outputs balanced?

On both the SM 26, 26B and the current 26S all inputs are fully balanced. The first model SM 26 has only balanced inputs, the outputs are single-ended (some say quasi-balanced) with an ungrounded "floating" sleeve connection. For typical applications this is not a limitation, just a consideration for wiring and RF rejection. The SM 26B has been in continuous production since 1994, replacing the SM 26. The "S" version has a new internal universal power supply, operating from 100-240 VAC (true for all Rane "S" models).

When I split and mix simultaneously there is phase cancellation at the MIX OUTPUTS, what's wrong?

Due to the summing node being inverting there is a combination of hookups which will produce phase cancellation due to signal inversion. Remove the internal jumpers (six total) to rectify this situation. Only SM 26B units have these jumpers, they were not part of the SM 26 design. Sorry for those using older pieces to the limits.

SM 82 / 82S:

Are the inputs balanced?

No. This piece is primarily aimed at the keyboard and similar sources. If you need fully balanced inputs use the SM 26S or the MLM 82S. However, the SM 82 outputs are balanced.

Can I modify the unit's aux send to be pre fade?

This unit is really packed tightly and just doesn't allow room for this. The performance would be seriously compromised, and because it's a double sided board a modification would take four or five hours if you really knew your way around inside the unit.

SR 1L:

I just wired multiple units up, checked all my connections, yet the remote won't respond correctly. What's wrong?

Make sure that every SR 1L is set to its own address, using the DIP switches (earlier style) or Rotary selector on the side of the piece. Additionally make sure to use good quality wiring, (like CAT 5) to assure consistent communication with the SRM 66.

SR 2 / 3 / 4:

One or more remotes has a flashing red LED and won't control the RPM unit. What's wrong?

Make sure that every remote is set to its own address, and check to be sure the A and B data lines are not reversed. Equally important to correct wiring is using pairs of twisted conductors (i.e. A = blue w/ white, B = blue, V+ = green w/ white, V- = green etc.). Don't mix wires from different pairs. Also do not "double up" extra pairs on the A and B data lines, as the extra capacitance can affect communication.

I have remotes connected to an RPM xx and can upload / download to / from the SR 3s but they will not "talk to" (control) the Drag Net unit. Is there a setup issue or am I missing something?

The RPM xx polls (searches) for Smart Remotes when it is first turned on. It's sort of a roll call to see which addresses are being used. Any devices connected correctly are seen and commands from them recognized. However any remotes not connected and powered up at the moment power is supplied to the RPM xx will be ignored. The first resolve is always to cycle the power at the RPM xx (unplug it, and plug it back in). Typically this cures the "my remotes don't work" symptom. For the computer types out there, this operation is very much the same as polling for SCSI hard drives at boot-up. Only active devices found during polling will be useable by the computer.

I have remotes connected to an RPM 88, but some are not working are appear completely dark

The RPM 88 can only power three SR 3 or six SR 4 remotes. If more remotes will be used on an RPM 88, then an external power supply must be utilized (do not connect any wires to the V+ and V- terminals of the RPM 88 in this instance). Refer to the zipped Excel file: SR Cable Length Calculator Spreadsheet for specific details on wiring, power consumption and other details.

SRM 66:

I just set the unit up, checked all my connections, but still get no sound. What's wrong?

When the unit is initially powered up all the outputs are muted. Run through the setup procedure in the manual and make sure the the inputs are assigned correctly to the applicable groups. Also be sure the groups are assigned to the outputs in use. (SR 1L remote users must also assign remotes to groups.)

How do I set the unit to operate in Binary mode?

Simply hardwire connect the Memory Recall Port (MRP) terminals numbered 5, 6 and 8 to the COM terminal. This will enable the unit to accept binary memory recall input and yield 24 memories.

Can I connect a microphone directly to the unit?

No, the SRM 66 is a line level device. It will accept levels from consumer - 10 dBV or professional + 4 dBu sources but a preamp, like the MS 1b, is needed between the microphone and the SRM 66.

How do I externally control an SRM 66 from an AMX or Crestron?

First read Using a Control System with an SRM 66 and then the following:

There are 3 modes of operation for the SRM 66 (RIP, DSC, SLAVE). To externally control the SRM 66 (with AMX or Crestron) you must use either DSC or SLAVE mode. DSC allows for full access, while SLAVE only controls SRM 66 Group Levels and Memories. If all you need is to control output levels and memories, SLAVE mode is by far the easiest.

AXCENT3 Wiring:
SRM 66 AMX Description
GND 5 Shield
A 4 & 6 Data +
B 1 & 9 Data -

Protocol:
RS-485 9600 kb, 1 Stop, 8 Data, No Parity
AMX demo programs (on web or RaneROM):
DSC mode SRM_DSC.AXS
SLAVE mode SRMSLAVE.AXS

Note the SR 1Ls do not need to be connected. The programs scan for the SR 1Ls during power-up, and if they are not found they are ignored.

THX 44:

Is it possible to hookup the unit using both the RCA and D connectors at the same time?

For the inputs it is important to use only one connection or the other. On the outputs it is permissible to use both the RCA and D connectors simultaneously. (D type THX interconnect cables are available through home theater dealers.)

TTM 52/i/54/i:

What's the difference between the "i" version and the "non-i"?

Original TTM 52 and TTM 54 models were built with metal toggle switches (ST 1) and a painted steel Decor plate (the one the faders stick through). When we revamped the design, we spread the controls apart slightly and added a Lexan covered Decor plate, as well as changed to larger plastic "bat handle" toggle switches (ST 2). Neither the Decor plate nor switches can be swapped between versions. Functionally and electronically the two versions are identical. No sonic or specification changes were made --- except the replacement switch part numbers.

Can I install the new no-contact magnetic fader from the TTM 56 into my TTM 52 or 54 mixer?

No. Our new state-of-the-art proprietary magnetic fader cannot be installed into any other mixer. It only works in the TTM 56.

Can I use both the RCA unbalanced and 1/4" balanced outputs at the same time?

Yes. Just be aware of the possibilities of creating a ground loop and hearing an annoying hum.

Is the TTM 52 built with the same quality as the TTM 54?

Absolutely! The TTM 52 and TTM 54 are both built with the same components and hand assembled quality right here in beautiful downtown Mukilteo WA. USA, as are all Rane products.

TTM 56:

Will the no-contact magnetic fader work in any other mixers?

No. This very complicated precision device is engineered to work only within the TTM 56 architecture. It is not compatible with any other units.

How can I order a spare fader for my TTM 56?

We do not sell the complete fader for this mixer. It is not necessary to replace the entire fader. As a service spare part, the carrier assembly (part number 13188) is available. it consists of the Delrin housing, with magnet installed and pre-aligned torsion spring. This three-piece entity is all that will be necessary for field repairs. Any work beyond replacement of the carrier needs to be done here at the Rane factory. TTM 56 mixers are Factory Service Only so parts and schematics are not available outside the factory.

I've seen P & G faders available for the TTM 56 over the internet. Why doesn't Rane list them as an option?

Rane does not offer Penny and Giles faders for the TTM 56 because they will NOT work in the mixer. The circuitry which reads the no-contact magnetic faders is not calibrated and cannot be reset to operate with the P & G faders. Plugging in one of these devices will cause very abnormal responses from the mixer and should be avoided. Do not be fooled by the misinformation listed by some vendors on the internet. These are the facts from the company that designed the mixer.

The fader doesn't feel right. It seems to stick or bounce back a little. What can I do? Can I take out the spring or adjust it?

Oiling is the best way to address a fader drag problem. Remove the face plate and apply lubricant to the support rod near the spring. If the rod is dirty, carefully clean with a lint free cloth before lubricating. A great way to polish the rods and remove accumulated contaminants is to tear off a strip of newspaper wide enough to fit around the exposed length of rod, and wrap it around the shaft. Then you can pull strip back and forth to buff the rod (think of it like polishing a shoe, but in reverse). Once this is done, the dirt will have been wiped away and a clean stainless shaft is ready for oiling. We recommend true silicone lubricant, commonly available at hardware stores and automotive parts retailers. Sewing machine oil is probably okay. Bending the spring may permanently damage it, and will void your warranty. When performing any maintenance, use common sense and proceed very carefully.

For those who wish to obtain almost zero drag on the fader, gently push the spring downwards towards the circuit board, and rotate out from under the rod, then release. The spring will be above the rod and not making contact. This setting allows the fader to move more easily. This can make controlled fading difficult, because the fader moves freely when released. You will not hurt the fader operating it this way. Small mechanical parts are easily damaged, so use care when lubricating or moving the spring.

What are the differences between the TTM 56 and the TTM 56i?

There is no such model as the TTM 56i. We have only made the TTM 56. It has two versions earlier and later, distinguished by the knobs and front panel graphics. The latter has taller rubber knobs and rounded piping highlights for the graphics.

I cannot figure out how to make the effects work. What am I doing wrong?

The TTM 56 does not have any built-in effects processor. You must connect a separate outboard unit.

I cleaned / lubricated the fader and it feels better, but now it won't turn off all the way (bleeds) when I have the contour set to fastest cutoff. What happened?

The hall sensor got pushed (bent) and is now too far from the magnet. Look for a small black plastic device --- about 1/8" square --- just below the rods at each end of the fader, mounted on the circuit board. It needs to be perpendicular to the PCB. If the sensor has been "bumped" during cleaning / lubrication, then it will not be close enough for the magnet to "turn off" the fader completely, resulting in bleed. Fix the problem by gently bending the sensor towards the middle of the fader, closer to the magnet. It doesn't take much movement to get it correct, so proceed carefully. A paper clip used gently works well, as will a very small screwdriver. If you break the sensor off, you'll need to get another fader so be extra cautious.

Via 10:

Can I use the Rane Via 10 to control other devices? I am looking to create a bridge between a laptop and an RS-232 device made by another manufacturer.

I want to be able control the RS-232 over a long distance and make it network controllable over Ethernet. Possible??

Unfortunately, you cannot easily control other RS-232 devices through the Via 10 because of the following problem. If you're running software on the laptop that sends its commands out the RS-232 port (which is likely for 232 device software), you have to figure out how to get the software's commands onto the Ethernet network. This involves some type of Ethernet protocol which must be "known" and therefore decoded by the receiving device (Via 10) at the non-laptop end. I've heard there's an Australian(?) company that has written a driver that -- inside the PC -- converts the 232 data into an IP stream. We don't know this company (write us at Service). BUT -- since the protocol that such an Australian company decides to use is unknown by the Via 10, the Via 10 cannot be used to decode the IP data back into RS-232.

Our RaneWare software (and therefore all our RW 232 products) have the ability to send control data over the laptop's Ethernet port rather than the RS-232 port on the laptop. So, we have solved this problem for our 232 products since the Via 10 is aware of the IP data's structure and can properly decode it. There is a menu pick in RaneWare to send control data out the Ethernet port instead of the 232 port.

The Via 10 Manual implies this type of functionality but one must use the ActiveX controls and write your own software that enables this. It's a bit of a task since the entire 232 protocol of the device(s) to be used must be thoroughly understood and supported using ActiveX and the associated string handling and/or handshaking of the 232 data. You also have to handle this on all ends of the network connection(s). We've made this easy with our own 232 products, though it is unlikely that we will spend the time to write drivers to handle the multitudes of RS-232 device protocols that are out there. Some year perhaps there will be a standard way that any RS-232 data can be bridged on and off of Ethernet. Until then, it's some work to solve this problem.

Here's a link to a possible solution for this 232 to Ethernet problem. It doesn't involve a Rane device, but it may do the trick? Intelligent Instrumentation Serial EDAS

Detailed Slide Pot Care Procedure

Although Rane does not expect slide pots to need routine cleaning, there are certain harsh environments where this may prove beneficial.

Supplies
The only product authorized by Rane for use in our potentiometers is CAIG Laboratories DeoxIT Faderlube.

Procedure:
1. Make sure the equipment is turned off and preferably unplugged.
2. Position the fader to be cleaned in such a way that it is easily accessible.*
3. Cover and protect any finished surface which may be affected by over-spray.
4. Using the spray tube, apply three short bursts of DeoxIT Faderlube 5% carefully into the control. This is CAIG part number F5S-H6 in a 5 ounce aerosol. If done regularly, in many situations this is sufficient maintenance and no further lubrication is necessary.
5. Operate the control through its entire travel to distribute the cleaner.
6. Collect any excess cleaner and prevent it from flowing uncontrolled.
7. Apply three more short bursts of DeoxIT Faderlube 100% for additional lubrication. This is CAIG part number F100S-L2 in a 2 ounce aerosol.
8. Again, work the lubricant into the device by operating the control repeatedly.
* The monorail crossfader used in all "z" mixers the TTM 52 and TTM 54 must be removed from the unit to apply cleaner-lubricant.
At this point the control should be operational. If fader performance is questionable then replacement of the pot is the only sure remedy.

Maintenance Intervals:
Products which are used in harsh environments should be cleaned and lubricated regularly. Interval to be determined by the user. Slide controls that are scratchy intermittent or mechanically binding should be cleaned immediately to prevent further wear to the component.
