Important Safeguards

WARNING: TO REDUCE THE RISK OF FIRE OR ELECTRIC SHOCK,
DO NOT EXPOSE THIS APPLIANCE TO RAIN OR MOISTURE.

CAUTION: TO REDUCE THE RISK OF ELECTRIC SHOCK, DO NOT
REMOVE COVER. NO USER - SERVICEABLE PARTS INSIDE.
REFER SERVICING TO QUALIFIED SERVICE PERSONNEL.

The lightning flash with arrowhead symbol, within an equilateral
triangle, is intended to alert the user to the presence of uninsulated
“dangerous voltage” within the product’s enclosure that may be of
sufficient magnitude to constitute a risk of electric shock to persons.

The exclamation point within an equilateral triangle is intended to
alert the user to the presence of important operating and mainte­nance (servicing) instructions in the literature accompanying the
appliance.

POWER CORD NOTICE FOR INTERNATIONAL OPERATION
For 230V, 50Hz operation please select the power cord for your
area. Select the plug for your area at one end and a IEC320 con­nector at the other. It is not necessary to make any other
changes. If you have any questions please call Russound Inc. at
1-800-638-8055 or 603-659-5170

Safety Instructions:

1. Read Instructions - All the safety and operating instructions should be
read before the appliance is operated.

2. Retain Instructions - The safety and operating instructions should be
retained for future reference.

3. Heed Warnings - All warnings on the appliance in the operating instruc­tions should be adhered to.

4. Follow Instructions - All operating and user instructions
should be followed.

5. Water and Moisture - The appliance should not be
used near water; for example, near a bathtub, wash­bowl, kitchen sink, laundry tub, in a wet basement,
or near a swimming pool.

6. Carts and Stands - The appliance should be used only
with a cart or stand that is recommended by the manufacturer. An
appliance and cart combination should be moved with care. Quick

as radiators, heat registers, stoves, or other appliances (including
amplifiers) that produce heat.

10.Power Sources - The appliance should be connected to a power supply
only of the type described in the operating instructions or as marked on
the appliance.

11.Grounding or Polarization - Precaution should be taken so that the
grounding or polarization means of an appliance is not defeated.

12.Power Cord Protection - Power supply cords should be routed so that
they are not likely to be walked on or pinched by items placed upon or
against them, paying particular attention to cords at plugs, receptacles,
and the point where they exit from the appliance.

13.Cleaning - The appliance should be cleaned only as recommended by
the manufacturer.

14.Non-use Periods - The power cord of the appliance should be
unplugged from the outlet when left unused for a long period of time.

15.Object and Liquid Entry - Care should be taken so that objects do not
fall and liquids are not spilled into the enclosure through the openings.

16.Damage Requiring Service - The appliance should be serviced by quali­fied service personnel when:

A. The power supply cord or the plug has been damaged; or
B. Objects have fallen, liquid has been spilled into the appliance; or
C. The appliance has been exposed to rain; or
D.The appliance does not appear to operate normally; or
E. The appliance has been dropped or the enclosure is damaged.

17.Servicing - The user should not attempt to service the appliance beyond
that described in the operating instructions. All other servicing should
be referred to qualified service personnel.

Precautions:

1. Power – WARNING: BEFORE TURNING ON THE POWER FOR THE
FIRST TIME, READ THE FOLLOWING SECTION CAREFULLY.
All models are designed for use with either AC120V, 60Hz or AC240,
50Hz voltages. The unit will autoswitch to either of these voltages

2. Do Not Touch The PR-4Zi With Wet Hands – Do not handle the PR-4Zi
or power cord when your hands are wet or damp. If water or any other
liquid enters the PR-4Zi cabinet, take the PR-4Zi to a qualified service
person for inspection.

3. Location of PR-4Zi – Place the PR-4Zi in a well - ventilated location.
Take special care to provide plenty of ventilation on all sides of the PR­4Zi especially when it is placed in an audio rack. If ventilation is
blocked, the PR-4Zi may overheat and malfunction. Do not expose the
PR-4Zi to direct sun light or heating units as the PR-4Zi internal com­ponents temperature may rise and shorten the life of the components.
Avoid damp and dusty places.

4. Care – From time to time you should wipe off the front and side panels
of the cabinet with a soft cloth. Do not use rough material, thinners,
alcohol or other chemical solvents or cloths since this may damage the
finish or remove the panel lettering.

The PR-4Zi 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 PR-4Zi allows
zone settings to be stored and recalled. SYS­TEM ON and SYSTEM 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 PR-4Zis. An RS-232

AUDIO/VIDEO SOURCES

Make line level and composite video connections
from source equipment to the PR-4Zi as shown
in Figure 1. Use high quality cables that are as
short as possible to keep signal integrity intact.

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.

CONNECTING AMPLIFIERS

Connect the Zone Output of each PR-4Zi zone to
one line input of a multichannel amp. Figure 2
shows a connection to the Russound DPA-6.12
Twelve Channel Audio Amplifier. (Figure 2 also
shows a trigger connection, discussed on p. 6.)

Figure 2 – Multichannel amplifier connections, with tirgger connection shown to one channel

If using multiple two-channel amplifiers, such as
the Russound DPA-1.2, connect as shown in
Figure 3 (see p. 6). Use good quality audio
cables that are as short as possible to keep sig­nal integrity intact.

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.
