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.
