Although Rane does not expect slider or rotary pots to need routine cleaning, there are certain harsh environments where this may prove beneficial. These instructions are for audio slider and rotary potentiometers, not the no-contact magnetic faders found in our newer DJ mixers. For these, click "Magnetic Fader Care" at the left.
Lubricant / Cleaner
Rane recommends CAIG LaboratoriesDeoxIT® Fader F-Series 5% Solution.
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 Fader 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. Again, work the lubricant into the device by operating the control repeatedly.
At this point the control should be operational. If fader performance is questionable then replacement of the pot is the only sure remedy.
Products which are used in harsh environments should be cleaned and lubricated regularly, the interval can be annual, or determined by the user. Slide controls that are scratchy, intermittent or mechanically binding should be cleaned immediately to prevent further wear to the component.
These Rane faders are magnetic:
These faders and crossfaders are designed with materials highly resistant to corrosion and most chemicals. While they will handle millions of operations, they may become dirty over time. Bad things may be spilled into a fader, but in many instances the fader may not be damaged and the sound quality thus unaffected. Cleaning is only required to maintain the feel of the fader.
In order to maintain the feel of your faders, they may occasionally require cleaning and lubrication. The bearings in the fader work best with DuPont Teflon Multi-use Lubricant (4 oz. drops bottle). A link at this page has "where to buy" sources. Make sure to follow the instructions and warnings on the bottle.
This lubricant goes on wet to deeply penetrate moving parts, but sets up with a clean, dry, long-lasting film which will not attract and absorb dirt and grime. Wet or oily lubricants may feel good at first, but will attract dirt and evaporate or become dry over time.
|There are two versions of the Rane magnetic fader. The first version was shipped in Rane mixers made 2001-2012, and included a torsion spring. Be careful not to bend this spring.|
|The new magnetic fader is in units made since December 2012, and does not need the spring. The new fader can replace the previous one if needed. If one magnetic fader needs replacing, we recommend replacing all the magnetic faders to match the same "feel."|
Clean one fader at a time by removing the fader from the mixer. Fader removal instructions are in each mixer's manual. If you remove more than one fader, mark it to be sure it goes back in the very same position, as the faders are calibrated at the factory.
1. For a light cleaning, move the carrier to one side and wipe rails with a lint-free cloth. Move the carrier to the other side and repeat.
2. If a thorough cleaning is required to remove any contanimants, first take the carrier off of the rails by removing the endblock opposite the ribbon cable connector. Clean the rails using isopropyl (rubbing) alcohol. Use a cue-tip and alcohol to clean the carrier bearings. Dry the rails using a lint-free cloth.
3. With the fader clean, dry and re-assembled, add a couple of drops of Teflon Multi-use Lubricant to each rail of the fader.
4. Move the carrier back and forth to distribute lubricant.
5. Do not disturb the position of the small sensors at each end of the fader. If you accidentally do, make sure the parts are standing straight before re-installing.
6. Important note for TTM 56, TTM 56S and TTM 57SL faders! When re-connecting the ribbon cable to the main PCB board of the mixer it is extremely important to match up the red line on the ribbon cable with the #1 on the main PCB board next to plastic connector jack housing. It is also important to fasten the ribbon cable connector into the six prong connector jack housings on both the fader board and the main PCB. Failure to do either will result in burning out the hall sensors, making the fader inoperative.
After cleaning or replacement, the sensors may get moved, affecting the contour. After any fader service, perform this procedure to re-calibrate the faders and crossfader.
1. Power off the mixer.
2. Move all faders to the center-most position.
3. Push down both PGM 1 CUE and PGM 2 CUE buttons at the same time.
4. While holding these buttons down, power on the mixer.
5. Immediately after fading up, the CUE lights will flash one time, indicating a successful calibration. If the CUE lights flash three times, the sensors may have moved too far, or all faders were not properly centered, and the faders cannot correctly calibrate.
"I'm a DJ, I just want to install a fader and go. I can't solder and don't want to anyway."

What is your mixer model? (click on it below, then check the part at the top of your browser screen)
Any "x" series mixer (MM 8x, MP 22x, MP 24x) used plug-in assembly 08951. Pot only is part number 03505 - no longer available. Use F45 or F60 with FX Crossfader Adapter part 16832.
Any "z" series mixer (MM 8z, MP 22z, MP 24z) and XP 2016/a uses plug-in assembly 16251. Pot only is part number 08755.
Any TTM 52/i or TTM 54/i versions used plug-in assembly 16254. Pot only is 09524.
MP 44 uses plug-in assembly 11646. Pot only is 08755.
MP 44 uses plug-in assembly 11646. Pot only is 08755.
The original MP 22 and second generation MP 24 mixers use a plug-in crossfader (it just has CROSSFADE on the metal plate) which Rane no longer carries. We do have the pot available, but you must solder it in place and reuse the plug-in hardware. If you've lost the crossfader assembly for an MP 22 or MP 24 you're out of luck. We no longer have any crossfader assembly parts for these decade-old units. This pot also fits the original MP 24 which has a power switch on the front panel, and does not use a plug-in crossfader. Any mixer before the "x" version (MP 22 or MP 24) no longer has a plug-in assembly available. For the MP 22 and MP 24 order a replacement pot like this:
This is part number 00907. Do not discard the plug-in assembly from an MP 22 or MP 24 as we no longer have any spares available. In other words, if you've lost or tossed the assembly you're out of luck. The mixer will "work" without a crossfader, but it's just not the same.
When ordering a crossfader assembly, you must provide the mixer's serial number. No serial number means no return if it doesn't fit!
