Product Overview

The CP 4.6 is a four-zone, six-source A/V preamplifier
that offers independent control of source, volume, and
tone for each zone. In addition to standard preamplifier
controls, the CP 4.6 allows zone settings to be stored
and recalled. ALL ON and ALL OFF functions provide
single-button, system-wide on/off control. Two PARTY
modes link all zones for synchronous operation.
Interface connections are provided for cascading as
many as four CP 4.6s. An RS-232 port allows the CP 4.6

to be controlled by touch panels or other automation
devices that have an RS-232 interface. Optional
Russound PCK or PCK-IR Keypads provide easy remote
operation of the CP 4.6. The optional Russound PRC-1
Learning Remote allows users to operate source equip­ment from remote locations. Optional Russound SPG
and PTM-1 Paging Modules add whole-house paging
capabilities.

Figure 4 – Common and Zone trigger outputs

COMMON AND ZONE TRIGGER OUTPUTS

The CP 4.6 provides four Zone-Specific and one Common
+12VDC trigger outputs (Figure 4). The Zone-Specific
triggers are turned on when the corresponding zone is
on. The Common trigger is turned on when any zone is
on. All trigger outputs are turned on during a page.
Figure 2 (p. 5) shows a Zone trigger connection to the
Russound DPA-6.12 amplifier.

Wiring Instructions

CONNECTING VIDEO MONITORS

Each CP 4.6 zone has a composite video output to allow viewing video from any of six A/V sources. Connect monitors
as shown in Figure 5 using RG6U cable with RCA type connectors. If more than two monitors are being used in a
zone, a composite video distribution amplifier is recommended. The CP 4.6 video outputs are buffered and are good
for up to 100’ of RG6U.

Figure 5 – Video Output connections

Figure 6 – Source Loop outputs

SOURCE LOOP OUTPUTS

The CP 4.6 has six buffered, fixed-level
audio/video outputs (Figure 6). When set to
SOURCE LOOP OUT, these output signals from
the corresponding input source. This source loop
configuration allows the CP 4.6 to pass source
signals to another component, such as a home
theater controller, or to another CP 4.6 for shar­ing sources in a multiple controller system.

Wiring Instructions

FIXED ZONE LINE OUT: CREATING SUBZONES

The CP 4.6 has six buffered, fixed-level audio/video outputs as shown previously in Figure 1 (p. 4). When set to
FIXED ZONE LINE OUT (Figure 7), the last four outputs can be used to create subzones of each main zone.
A subzone gets the same source selected for the main zone, and therefore needs only on/off and volume control.

The lower portion of Figure 7 shows four amplified Russound A-KP keypads added to Zone 1. All subzones get the
same Zone 1 source, but will have independent on/off and volume control via the A-KP keypad.

Figure 8 – Paging trigger output
and mute input

PAGING TRIGGER OUTPUT

The CP 4.6 is equipped with a paging trigger output
(Figure 8) that switches on during a page. This output
can be used to trigger an external amplifier, muting
device, or other peripheral associated with paging.
(Paging peripherals are discussed on page 14.)

MUTE INPUT

The CP 4.6 system mutes when a +12VDC signal is
applied to the mute input (Figure 8). This allows
connection of external paging or muting devices.

PAGING

The CP 4.6 has five paging inputs. The four Zone­Specific PAGE INPUTS allow for paging to all zones
except the zone where the page originates. The PAGE
ALL input will allow paging to all zones. A page turns on
all zones to their respective preset paging volume (see
Memory Procedure, p. 11). All devices triggered by any
of the trigger outputs will also be turned on. Russound
offers many paging options to suit most applications.
See the Tech and FAQ sections at www

.russound.com

or call Russound for additional information.

SPG PAGING MODULE

The Russound SPG provides "push-to-talk" operation.
Use 22-24 AWG twisted pair shielded wire to connect
the SPG to the CP 4.6 page input as shown in Figure 13.

PTM-1 PAGING MODULE

The Russound PTM-1 is a signal-sensing paging adapter
for the CP 4.6 that accepts the page output or other
line-level audio output from telephone paging systems,
paging preamplifiers, switch-triggered voice/sound
recording devices, etc. Use 22-24 AWG twisted pair
