CP52S Commercial Processor

The CP52S is a versatile commercial preamplifier designed for use in restaurants, bars, health clubs and offices. The CP52S serves one stereo Zone. One gated Paging Input and four stereo Program Inputs are provided. A Port allows expansion of Page, Program or Zone signals. Three levels of priority are supported:

  1. Page
  2. Program Priority
  3. Non-Priority Program

The Paging Input is summed after Zone Level, Zone EQ and Zone Limiter circuits. If the Page Level Tracks Zone Level switch is on, the Page level tracks the Zone Level.

One of four stereo Program Inputs may be selected. Each line level Program Input features an independent Level control. A gated Program Priority Input is provided. When the rear panel Priority switch is ON and signal is detected at the Priority Input, it overrides any non-priority Program selection. The detector features adjustable Detect Threshold and Release Time controls.

SCP 1S CoverSeveral levels of security are available. The SCP1S is an optional EQ-slider-only security cover. Any front panel control knobs may be removed and replaced with hole plugs provided with the SCP1S. The SC1.7 is an optional security cover for the entire unit.

CP52S Block

ZR1 Remote

ZR 1

The optional ZR1 wired Remote Control allows Zone Level and Zone Program selection of the CP52S from within the Zone area. Remote control is initiated by engaging the RMT switch (located on the CP52S front panel). The ZR1 may be installed in a standard electrical box and finished with a Decora™ plate.

If you need only a volume control, see the VR1 Volume Remote.

If you only want a few volume presets, see the LRS 4 Level Recall Remote.

PR 2 & ZR 1 Schematic

The ZR1 connects to the CP52S through a 5-pin Euroblock connector. The remote uses 5 wires with 2 bits for Zone Program selection (active low Gray Code), a common shield/gnd and two wires for ratiometric DC control of Zone Level. Selector logic is active low Gray Code with pull-up provided in the CP52S. Control may be a simple switch closure to GND or 5 volt TTL.

Application: Restaurant

CP52S Background Music and Paging System

Paging mic from reception, 4 music sources, remote for source selection and volume within the lounge.

Program Source - Allows the use of up to 4 stereo sources such as TV audio or a Music service.

Jukebox - This Input allows a Jukebox to automatically override the selected Program source when it is turned on.

Multichannel Amplifiers - The MA4 is 4 channels @ 100W 8 ohms, or use the MA3 with 3 channels @ 40W 8 ohms.

Page - will automatically duck the chosen program material. It has first priority.

ZR1 Zone Remote - Allows remote control of Program Selection and Zone Level within the restaurant or lounge.

Zone 1 - Can be stereo in the lounge.

Zone 2 - Is mono in the restaurant, using a MT 4 or MT 6 for transformer distribution to 70V or 25V speakers.

CP52S Application: Cardio Fitness Room

CP52S Cardio Sound System

The CP52S offers a few features not found in other aerobic room rack mixers.

All the instructor needs is to turn on the the headset, and start an MP3 dock or other source that's plugged into the Priority input. The source automatically switches to the Priority music source, and switches back when that source is turned off. A wired remote control (ZR1) can manually change the source or volume from a wall plate, or mounted on the side of the locked equipment rack.

The CP52S can stay in a secure locked rack. This protects the settings and EQ so the instructor can easily learn and know the system without surprises. When cardio class isn't in session, the CP52S can supply the club background music from the satellite music service to the big speakers in the cardio room at a predetermined input level.

Program Source - Allows the use of up to 4 stereo sources such as TV audio, CD or music service.

MP3 - This Priority Input allows a laptop, CD or MP3 player to automatically override the selected Program source when it is turned on.

Wireless headset and receiver - can automatically duck the chosen program material by a chosen variable amount, preventing volume overload to the ears in the class.

ZR1 Zone Remote - Allows remote control of Program Selection and Level to the stereo room speakers.

Expand Output - Though a satellite music service could be one of the inputs, the Expand Output may run to the club background music system. This allows the music mix to play in the club without the wireless mic signal. A proper hookup assures that both would not be used at once.

CP52S Support

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 LED and open causes it to illuminate). 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 series 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 CP52S operate in Mono mode?

Yes. The CP52S has a Zone 1 Mono Switch on the rear panel.

When Zone 1 of the CP52S is in Mono mode, which output LEFT or RIGHT should I use?

Either output 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 on the rear panel can change the interval from five to twenty seconds.

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 VR1 to the CP52S 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 64S and ZR1 manuals for clarification.

I just installed a unit and don't get audio. Or I hooked up the ZR1 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 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 RMT switch is engaged. For testing, push the RMT switch and make sure it's in the "out" position. Then, re-test all functions of the CP52S. If all works fine now, the problem lies in the remote or wiring to it.

I can't get the page 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 switch correctly on the front panel. Once you have the setting correct, turn up -- clockwise -- the INPUT TRIM control and see if you can light the OL indicator when you yell into the mic. Now adjust the DETECT THRESHOLD to get ACTIVE to illuminate. If all this checks out, it's time to follow the Recommended Calibration Procedure in the manual.

Is it possible to use a single VR 1 to control volume remotely and still use the front panel program selector on the CP52S?

No, once the RMT switch is engaged on a CP52S, it disables the Program Selector switch. Using a VR 1 with CP52S yields only Line 1 input being available for that zone. Automatic switching to Priority / Line 4 program input is unaffected by this combination.

 Is it possible to use a single ZR 1 to control both zone selections on a CP52S?

Wiring D0 and D1 together on a CP52S will cause one remote selector to affect program choices in BOTH zones. It is not recommended to wire Vc together for single remote volume control, which also negates having two discrete zones in the first place. Use a ZR 1 for level control in one zone and a VR 1 for level control in other. ZR 1 selector then affects source choie in BOTH zones.
