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 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 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 PR4Zi video outputs are buffered and are good for up to 100’ of RG6U.
Figure 5 – Video Output connections
SOURCE LOOP OUTPUTS
The PR-4Zi 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
PR-4Zi to pass source signals to another
component, such as a home theater controller, or to another PR-4Zi for sharing
sources in a multiple controller system.
Figure 6 – Source Loop outputs

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 AKP 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
The PR-4Zi is equipped with a +12V 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 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.

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 output 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.
To connect multiple emitters to the
Common IR output, use the
Russound 857 connecting block
and a 1/8-inch (3.5mm), 2-conductor (mono) phone plug as shown in
Figure 18. Connect common (COM)
IR output to “IR INPUT” on the 857
connecting block.

Peripheral Devices
PRC -1 REMOTE CONTROL
The Russound PRC-1 remote control is preprogrammed to operate more than 1,000 audio and
video components, including the PR-4Zi. Set it up by
simply punching in a three-digit code that matches
your equipment. The PRC-1 also has the ability to
learn new functions, allowing you to customize it and
update it as you add new equipment. The PRC-1
operates up to eight different audio and video components in a home entertainment system.
The PRC-1 controls only the local zone you are in.
USING THE PRC -1 WITH THE PR-4Zi
To activate the PRC-1 for use with the PR-4Zi:
1. Turn on the PR-4Zi using its fr
ont-panel switch.
2. On the PRC-1, press the AUX and MUTE buttons
simultaneously, then release.
3. Point the PRC-1 toward the PR-4Zi and press the
three-digit code 0-8-1.
4. On the PRC-1, press the AUX button again to
store the code.
5. Henceforth, pressing the AUX button on the PRC1 accesses all the preprogrammed codes for the
PR-4Zi.
All the functions available on the PCK keypad are
also available on the PRC-1. NOTE: The PRC-1 can
turn on the local zone by pressing the POWER button, and turn off that zone by pressing the MUTE
button.

DB-25 MALE / MALE CONNECTOR
INSTALLING MULTIPLE PR-4Zi CONTROLLERS
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 functions can be used system-wide. (In order to
share sour
ces 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.)
Figure 20 – Interface cable connections for multiple PR-4Zi’s
Multiple Controllers
The DB-25 cable needs to be a straight passthrough or RS232C rated with a male connector
at both ends.
ie. Radio Shack Part # 26-233

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
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 command sent to that zone. Commands are sent as ASCII values, asynchronous, 4800 bps, 8 data bits, 1
start bit, 1 stop bit, no parity.
Figure 21 –_Controller Address Switch
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. volume 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 decimal values, asynchronous, 4800 bps, 8 data bits, 1 start bit, 1 stop bit, no parity.
