OPERATORS MANUAL CP 52

COMMERCIAL PROCESSOR

QUICK START

If you were the type that cheated on school book reports by just skimming through the reading assignments, then this

section is for you! It gives you not quite enough information to really know what you’re doing. But, if you follow the

recommended set up procedure, you should get at least a “B.”

Keep the amplifiers and the CP 52 turned off until all connections are made.

PAGE INPUT

Connect the PAGING INPUT to the Euroblock on the rear panel. On the front, select the appropriate MIC or LINE

switch position. Then set the gain with the PAGING TRIM control, then set the PAGING DETECT THRESHOLD and

finally the PAGING LEVEL. PHANTOM POWER, HIGH/LOW CUT FILTER and PAGE LEVEL TRACKS

ZONE LEVEL switches are located on the rear panel.

PROGRAM INPUTS

Connect line level program sources to the RCA PROGRAM INPUT jacks (LINE 1, 2, 3 & P). If you have a priority

program, like a jukebox, connect it to the PRIORITY Input. The Program PRIORITY assign switch turns priority

override ON or OFF. The Priority program is automatically selected when signal is detected at its Input. Set the

PROGRAM DETECT THRESHOLD and RELEASE TIME as desired.

ZONE EXPAND

Wire the ZONE EXPAND Output Euroblock as required to a mono feed delivering PAGE-only, PROGRAM-only or

ZONE (both) signal depending on the switch setting. This Output uses a cross-coupled line driver and may be used

balanced or unbalanced. Adjust the ZONE EXPAND LEVEL trim as desired.

ZONE OUTPUT

The ZONE OUTPUT uses a cross-coupled line driver and may be used balanced or unbalanced. Set the front panel

LIMIT THRESHOLD as required. Depress the MONO switch for a mono Zone.

ZR 1 REMOTE

You may use one ZR 1 Remote (sold separately) with the CP 52. Wire it to the ZONE REMOTE Euroblock as

indicated. If a ZR 1 remote is not used, any simple switch closure to GND will work for the D0 and D1 pins. These pins

are TTL compatible (0 to 5 VDC). The logic is inverse Gray Code. Any ground referenced 5 volt DC control may be used

as the input to Vc. Do not ground the Vr pin.

The CP 52 is very versatile. While this makes a large number of system applications possible, it also results in com-

plexity. For this reason, it is important to use an organized approach for setup and calibration. A highly recommended

setup procedure appears on page Manual-7. By following it you will encounter fewer problems and reduce the need to

increase our collective phone bills.

CAUTION: Never connect anything except an approved Rane Power supply to the thing that looks like a red

telephone jack on the rear of the CP 52. This is an 18 VAC center tapped power input. Consult the Rane factory for a

replacement or substitution.

WEAR PARTS: This product contains no wear parts.

CP 52 - FRONT PANEL 햲 PAGING TRIM control adjusts the Page Input preamplifier gain to match the microphone/source in use, not to set the Page level in the Zone Output. The range is 30 dB to 60 dB. 햳 PAGING MIC/LINE switch selects a 30 dB Input Pad when set to LINE. Phantom Power is disabled when LINE is selected. 햴 PAGING DETECT THRESHOLD sets the Page signal level required to gate a Page on and illuminate the ACTIVE indicator (see 햶). The range is -∞ (on) to +4 dBu.

CP 52 - REAR PANEL 햲 Chassis Ground Screw provides a convenient earth (technical) ground connection point. The CP 52 does not ground the chassis through the power cord. It is important that the unit be grounded. 햳 POWER jack accepts the cable from a Rane RS 1 remote power supply (included) or an optional Rane RAP 10 power supply. This is not a telephone jack. Use of a supply not approved by Rane may damage the unit and void the warranty.

CP 52 CONNECTION Be sure the power to the CP 52 is OFF until all connections are made. EUROBLOCK CONNECTIONS All Input and Output connections are made with Euroblock connectors except for the RCA Program Inputs. When wiring to Euroblocks, a minimum wire gauge of 22 is preferred for reliability. If the ground or shield wire is left shorter, it acts as a strain relief for the other wires. Cable with a flexible jacket is easier to use and less likely to damage the connections.

ZR 1 Program Select/Level Remote Control ZR 1 REMOTE INSTALLATION The CP 52 supports a wired remote for Zone Level and Zone Source selection. Wire lengths of up to 1000 feet are possible. A brief list of suitable wire types is provided below in the section on Wire Types. The ZR 1 remote provides Zone Level and Source Selection, allowing local control from inside the Zone.

RECOMMENDED CALIBRATION PROCEDURE The CP 52 is a very versatile instrument. While this allows it to conform to the requirements of a large number of system applications, it also results in complexity. For this reason, it is very important to use an organized approach to system calibration. Once the system is connected and the internal switches set for your specific application, it is important to take the time for proper calibration.

CALIBRATION 1. Connect the power supply and verify the PWR indicator lights. 2. Verify the Zone LEVEL control is set to maximum and that an active source is playing for each of the Program Inputs intended for use. Select each Program Input and adjust its Input Level control to be the very loudest you would ever desire. 3. Adjust the Zone LIMIT THRESHOLD so that it just starts to audibly reduce the output level. This ensures that the level will never be louder than the maximum level just set. 4.
