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 (300 meters) are

possible. A brief list of suitable wire types is provided here in the

Wire Types section.

The ZR 1 remote provides Zone Level and Source Selection,

allowing local control from inside the Zone. If only one of the

two controls is used, you may wish to remove the unused knob

and cover the hole with one of the plugs provided in the kit. If

you require one ZR 1 remote to control more than one unit, sim-

ply wire the ports in parallel. This may be done with the Selector

only, Level only or both.

Be sure Power to the CP 52 is off while all

remote connections are made. It is impor-

tant to ensure that the CP 52 Remote Port

is not subjected to sustained voltages outside

the range of 0 to 5 volts DC or high levels

of static. Inputs are protected—however,

caution is the better part of... you know. It is

a good idea to install the wiring, connect it

to the remote assemblies and then make the

final connections at the CP 52. Do not short

the Vr pin to ground. Although the pin is

CP 52 Audio 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 reliabil-

ity. 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. Avoid stripping

excess insulation. Inspect wires for nicks that may lead to wire

breakage. Fully insert each wire in the appropriate socket and

tighten the screw.

The Page Input is a true instrumentation amplifier and oper-

ates balanced or unbalanced. Expand and Zone Outputs are

driven by high quality cross-coupled line drivers and operate bal-

anced or unbalanced. Wiring is usually the same for both Inputs

and Outputs. Balanced operation is recommended. Balanced

wiring is logical, (+) to (+), (–) to (–) and shield to shield.

For unbalanced operation, we recommend using two conduc-

tor cable with shield. The cable is wired to the CP 52 the same

as for balanced operation. At the other end of the cable, connect

the (+) wire to signal “hot,” and both the (–) and shield wires to

ground (important).

If you use single conductor cable with shield, connect the

shield/gnd wire to both the (–) and shield pins at the CP 52. At

the other end of the cable connect the (+) wire to the signal “hot”

and the shield/gnd wire to ground. When unbalanced wiring

is used, it is very important for the CP 52 and any other unit

in the system to have good earth or technical grounds. If a unit

is located far from the CP 52 or is of a type that might create

grounding problems, use isolation transformers.

When connecting any CP 52 Output as unbalanced, use (+)

and ground — leave (–) floating.

Refer to the included RaneNote, “Sound System Interconnec-

tion” for more information on proper wiring procedures.

current limited, excess heat will be generated in the 5 volt supply

if a short occurs. Never subject the Vr pin to voltages above 5V.

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.

ZR 1 REMOTE MOUNTING

The ZR 1 remote assembly mounts in a standard U.S. electri-

cal box with a minimum depth of 2.25". Be sure to note the

wire color of each input in order to facilitate correct wiring to

the CP 52. Connect each wire to the 5-pin connector by fully

inserting it in the correct socket and tightening the screw. Make

sure the cable jacket is stripped back sufficiently to allow it to lie

in the electrical box with the remote assembly inserted. Use the

flat head #6 screws supplied with the kit to mount the remote

assembly and silk-screened front panel to the electrical box (see

diagram, next page). Note the “UP” arrow screened on the

printed circuit board of the remote (mount it pointing up).

The silkscreened front panel metal is painted on both sides.

This allows you to custom silk-screen the panel or add your own

custom decals. Simply install the modified front panel with your

art facing out.

Install each knob so that the line on the knob is properly

aligned with the silk-screening on the front panel of the remote

assembly. Install any Decora plate of your choice. For a secured

installation, you may wish to leave the knobs off and use a blank

Decora plate to cover the remote after adjustment.

WIRE TYPES

Variations in wire type do not greatly affect the performance

of the remote controls. However, 22-gauge stranded wire with

a flexible jacket is recommended. You may use 5-conductor

unshielded remote control signal cable for shorter runs (less than

200 feet [60 meters]) or 4-conductor (2 pair) shielded remote

control signal cable (use the shield as the ground return) for

longer runs (200 to 1000 feet [60 to 300 meters]). The type of

wire required is influenced by your installation and local electri-

cal codes.
