Product Overview
The PR-4Zi is a four-zone, six-source A/V pream-
plifier that offers independent control of source,
volume, and tone for each zone. In addition to
standard preamplifier controls, the PR-4Zi allows
zone settings to be stored and recalled. SYS-
TEM ON and SYSTEM OFF functions provide sin-
gle-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 PR-4Zis. An RS-232
port allows the PR-4Zi 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 PR-4Zi. 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.

COMMON AND ZONE TRIGGER OUTPUTS
The PR-4Zi 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 out-
puts 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 PR-4Zi 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 PR-
4Zi 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 PR-4Zi has six buffered, fixed-level
audio/video outputs (Figure 6). When set
to SOURCE LOOP OUT, these output sig-
nals from the corresponding input source.
This source loop configuration allows the
PR-4Zi to pass source signals to another
component, such as a home theater con-
troller, or to another PR-4Zi for sharing
sources in a multiple controller system.

Wiring Instructions
FIXED ZONE LINE OUT: CREATING SUBZONES
The PR-4Zi 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-KP2 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. Main zone control can be acheived by repeating IR commands in a sub-zone into the main
zones keypad input. D1 will accept IR signal for zone control.

PAGING TRIGGER OUTPUT
MUTE INPUT
The PR-4Zi is equipped with a +12V paging trig-
ger 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.)
The PR-4Zi system mutes when a +12VDC signal
is applied to the mute input (Figure 8). This
allows connection of external paging or muting
devices.

PAGING
SPG PAGING MODULE
The PR-4Zi has five paging inputs. The four
Zone-Specific PAGE INPUTS allow for paging to
all zones except the zone where the page origi-
nates. 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 sec-
additional information.
The Russound SPG provides "push-to-talk" opera-
tion. Use 22-24 AWG twisted pair shielded wire
to connect the SPG to the PR-4Zi page input as
shown in Figure 15.
PTM-1 PAGING MODULE
The Russound PTM-1 is a signal-sensing paging
adapter for the PR-4Zi that accepts the page
output or other line-level audio output from tele-
phone paging systems, paging preamplifiers,
switch-triggered voice/sound recording devices,
etc. Use 22-24 AWG twisted pair shielded wire
to connect the PTM-1 to the PR-4Zi page input
as shown in Figure 16.

IR EMITTERS
The PR-4Zi has seven IR outputs:
Source 1–6 and Common. Source
1–6 outputs are source-specific and
provide IR signals only to the
selected source; the Common out-
put provides IR signals to all
sources.
Source-specific IR outputs (Figure
17) are useful when a system has
two or more of the same model
source component, allowing you to
target the IR commands to each
individual component.

As many as four PR-4Zis can be cascaded via
DB-25 connectors. Cascading links multizone
functions such as SYSTEM ON, SYSTEM OFF,
PAGING, and PARTY mode so that these func-
tions can be used system-wide. (In order to
share sources among linked PR-4Zis you must
connect the Source Loop outputs of the parent
controller to the A/V inputs of controller #2, and
so on.)
The DB-25 cable needs to be a straight pass-
through or RS232C rated with a male connector
at both ends.

Using the RS-232 Communications Port
The PR-4Zi is equipped with one DB-9 connector for RS-232 communication with AMX™, Crestron™,
and similar automation systems. All PR-4Zi control functions (except for paging) can be accessed
through the RS-232 port. The PR-4Zi will also send confirmation data to the controlling system. These
updates will be performed when any change has been executed or when the “SEND ZONE STATUS
INFORMATION” request is sent to the PR-4Zi.
CONTROLLER ADDRESS SWITCH SETTINGS
Figure 21 –_Controller Address Switch
Up to 16 zones can be controlled from a single RS-232
port by setting the Controller Address Switch located left
of the DB-9 connector (Figure 21).
Controller #1 (Zones 1-4)
Controller #2 (Zones 5-8)
Controller #3 (Zones 9-12)
Controller #4 (Zones 13-16)
RS-232 COMMAND PROTOCOLS
Commands are sent from RS-232 controlling device to the PR-4Zi as 8 ASCII bytes. The first two
ASCII bytes “RU” establish that the command is a Russound command for zone commands only. The
next 3 bytes “Z01” establish the zone to be controlled. The last 3 bytes “ZON” comprise the com-
mand sent to that zone. Commands are sent as ASCII values, asynchronous, 4800 bps, 8 data bits, 1
start bit, 1 stop bit, no parity.
PR-4Zi FEEDBACK BYTES TO CONTROLLING DEVICE
Feedback bytes will be sent immediately after a command is given to the PR-4Zi. The first decimal
byte “101” (Zone 1) establishes which zone the update is for. The second decimal byte “40” (min. vol-
ume has been set) is the update data. Each update starts with the zone number update value (101 -
116) and is followed by a control update value (see list on next page). Commands are sent as deci-
mal values, asynchronous, 4800 bps, 8 data bits, 1 start bit, 1 stop bit, no parity.
