The CP 52S is a versatile commercial preamplifier designed for use in restaurants, bars, health clubs and offices. The CP 52S 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:
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.
Several levels of security are available. The SC 1.7 is an optional security cover for the entire unit. The SCP 1S is an optional EQ-slider-only security cover. Any front panel control knobs may be removed and replaced with hole plugs provided with the SCP 1S.
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 the Jukebox to automatically override the selected Program source when it is turned on.
Multichannel Amplifiers - The MA 4 is 4 channels @ 100W 8 ohms, or use the MA 3 with 3 channels @ 40W 8 ohms.
Page - will automatically duck the chosen program material. It has first priority.
ZR 1 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.
ZR 1 RemoteThe optional ZR 1 wired Remote Control allows Zone Level and
Zone Program selection of the CP 52S from within the Zone area. Remote control is initiated by engaging the RMT switch (located on the CP 52S front panel). The ZR 1 may be installed in a standard electrical box and finished with a Decora™ plate.
The ZR 1 connects to the CP 52S 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 CP 52S. Control may be a simple switch closure to GND or 5 volt TTL.
If you need only a volume control, see the VR 1 Volume Remote.
If you only need a few volume presets, see the LRS 4 Level Recall Remote.
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.
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).
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.
Yes. The CP 52S has a Zone 1 Mono Switch on the rear panel.
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.)
Yes. The internal Program Priority Release Time control (location shown in the manual) can be rotated to change the interval from five to twenty seconds. Clockwise rotation increases the release time interval.
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 52S 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 ZR 1 manuals for clarification.
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 CP 52S. If all works fine now, the problem lies in the remote or wiring to it.
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.
If the above options don't answer your question, or it's urgent...
Phone 425-355-6000, 8 AM to 5 PM PST, Monday through Friday.
If it's less urgent, you can email the factory.
