Important Safety Information
The safety information in this summary is for installation and operating personnel. Warnings
and cautions can also be found throughout the manual where they apply.
CAUTION: TO REDUCE THE RISK OF ELECTRICAL SHOCK, DO NOT
REMOVE COVER (OR BACK). NO USER SERVICEABLE PARTS IN-
SIDE. REFER SERVICING TO QUALIFIED SERVICE PERSONNEL
The lightning flash with the arrowhead symbol, within an equilateral triangle,
is intended to alert the user to the presence of un-insulated "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.
WARNING: TO REDUCE THE RISK OF FIRE OR ELECTRICAL SHOCK,
DO NOT EXPOSE THIS APPLIANCE TO RAIN OR MOISTURE.
Read Instructions - All the safety and operating
instructions should be read before the appliance is
operated.
Retain Instructions - The safety and operating instruc-
tions should be retained for future reference.
Heed Warnings - All warnings on the appliance and in
the operating instructions should be adhered to.
Follow Instructions - All operating and use instructions
should be followed.
Water and Moisture - The appliance should not be
used near water - for example, near a bathtub, wash-
bowl, kitchen sink, laundry tub, in a wet basement,
near a swimming pool, and the like.
Wall or Ceiling Mounting - The appliance should be
mounted to a wall or ceiling only as recommended by
the manufacturer.
Heat - The appliance should be situated away from heat
sources such as radiators, heat registers, stoves, or other
appliances (including amplifiers) that produce heat.
Grounding - Precautions should be taken so that the
grounding means of the appliance is not defeated.
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 and plugs, convenience
receptacles, and the point where they exit from the

Power Source
This product is intended to operate from a power source that does not apply more than the
specified volts RMS indicated on the rear panel of the unit, as referenced between the supply
conductors or between either supply conductor and ground.
Grounding the PX-603 Multi-Room Expander
This product is grounded through the ground conductor of the power cord. To avoid the
potential of electrical shock, plug the power cord into a properly wired and grounded recep-
tacle before operating the PX-603. A protective ground connection, by way of the ground
conductor in the power cord, is essential for safe operation. A standard 3-pin IEC type in good
operational condition is the only acceptable cord that may be used to connect the PX-603 to a
power source.
Fuses
To avoid potential fire, electrical hazard and damage to internal components, replace fuses only
with fuses of the correct type, voltage and current rating as specified in this manual.
Removal of PX-603 Cover and Front Panel
To avoid personal injury and to ensure proper operation, do not remove the PX-603 cover or
front panel except as directed within this manual. Do not operate the unit without the covers
and panels properly installed.
Operating Environment
For the best operating results, install the PX-603 in an area where it will not be exposed to
direct sunlight or any heat source. The unit should be operated in a temperature range from
40˚ to 95˚F (5˚ to 35˚C). Place the unit where there is sufficient air circulation. It generates
heat and must be ventilated.
PX-600 Software
The PX-603 will only operate in PX-600 systems with software version 2.0 or above. See
page 1 of this manual for additional information.
KPS Software
KPS keypads must have software version 1.6 or above to operate correctly with the PX-600/
PX-603 system. See page 1 of this manual for additional information.

About This Manual
This manual contains information regarding the functions and installation of the Audioaccess
PX-603 Multi-Room Expander in new and existing PX-600 systems. Within it are revised
PX-600 programming instructions and updated KPS switch-setting data that augment the
material in the PX-600 Installation Manual. However, this manual does not contain the
essential instructions covered in the PX-600 Installation Manual.
Before you finalize your system design and begin installation, we suggest you review two
appendices of this manual. The Question and Answer appendix (Appendix II) contains actual
questions frequently asked by Audioaccess system designers and installers in conversations with
our Technical Support Department and during dealer training sessions. The straight-forward,
forum style explanations will help you better understand the interaction of the PX-600 and
PX-603 and help you make design choices early-on in system planning that will allow you to
configure a system that exactly matches your client’s needs. Furthermore, the System Design
Appendix (Appendix I) contains real-life descriptions of PX-603 applications, as well as repre-
sentative block and wiring diagrams.
We recommend that even experienced Audioaccess installers and system designers consider the
PX-600 and PX-603 Installation Manuals an essential part of their tool kit. For a complete
Audioaccess Technical Resource Manual which includes installation manuals, tech notes and
tech bulletins, please call our Customer and Technical Support Department at 860-346-0896.
PX-600 Software
To make existing PX-600 systems PX-603 compatible, you will need to upgrade the PX-600
software version to v. 2.0 or later. Earlier PX-600 software versions do not include the pro-
gramming screens for PX-603 setup. To determine the PX-600 software version, plug in the
PX-600 Programmer, press the PGM button, highlight ABOUT PX-600, and press ENTER.
The software version and date will appear on the programmer screen. All PX-600s shipped
after the release of the PX-603 will have v. 2.0 or later software installed.
KPS Software
To make existing KPS keypads PX-603 compatible, you will need to make sure they are
software version 1.6 or above. Earlier KPS software versions will not operate properly in
PX-600/603 systems. To determine the KPS software version, remove the wallplate surround-
ing each keypad and look for a pink dot on the mounting bracket. If a pink dot is not present,
or if the dot is another color, remove the keypad from the wall and remove the rear plate. The
software version should be on the processor I.C. itself. All KPS's shipped since July, 1994 have
software version 1.6 or above.

PX-603 Product Description
The PX-603 Multi-Room Expander allows the addition of three areas of independent volume
control to any existing zone or zones of a PX-600 Multi-Room Preamp/Controller system
without the use of autoformers. The chassis contains three line-level audio inputs, three stereo
amplifiers with digitally controlled volume and fixed equalization, and a four conductor
communication bus. Up to six PX-603s may be connected to any PX-600 in a system for a
total of 18 additional areas of independent volume control per PX-600. Each area may be
controlled from the traditional KPS eight-button, wall-mounted keypad or a KP3 three-button
keypad. An Audioaccess handheld IR remote control may be used with either keypad for
on/off, volume and source control for the entire zone through the IR receiver built into both
keypads.
Each PX-603 Audio Input receives a line-level signal from a PX-600 Zone Output. Room
configurations and independent bass equalization (3dB boost) are set via DIP switches on the
PX-603 rear panel. ALL-ON grouping and time-out features are programmed at the PX-600
control unit with a detachable PX-600 Programmer. Turn-on volume for PX-603 rooms is set
at the KPS or KP3 keypad in each room.
