FEATURES
Six Zone, Multi-Room, Multi-Source Audio System
Flagship of the Audioaccess product line, the PX-600 Multi-Room Preamp/Controller forms the heart of a powerful multi-
room audio system. Together with our time proven wall-mounted keypads and conventional audio source equipment, the
PX-600 allows you to access and control five different music sources in six different areas simultaneously. The PX-600
combines a learning IR based source controller with six independent stereo preamps to form a six zone system in one
compact package. Multiple PX-600s are easily interconnected to form systems as large as 36 independent zones and the
PX-600 can be readily interfaced to both complex home automation and home theater systems.
You can turn zones on or off, select sources, control their basic functions, and change volume independently in each
zone, by just the touch of a single button on the KPS keypad. And unlike rotary volume controls, our low profile keypad
blends seamlessly with any decor. The PX-600 can also be operated from its own optional handheld IR remote control
from any zone. Of course, the main zone can always be operated from the PX-600's front panel. Learning to operate the
system is simplicity itself. Keypads, remotes, and even the front panel have identical controls and operate in exactly the
same way.
Customized System Operation
The PX-600 is configured at the time of installation via a detachable handheld programmer that is available only to
authorized dealers, preventing casual tampering with the comprehensive system programming. Programmable features
include: turn-on volume, maximum volume, lockout, bass and treble settings for each zone, group setup, paging setup,
and specific IR protocols for tuners, CD players, high-capacity CD changers, tape players and VCRs, as well as special
macro commands tailored for control of popular surround processors.
Optional modules provide door chime and paging capability and an RS-232 interface for integrating the PX-600 with
computer-based home automation systems.
The PX-600 is complemented both functionally and aesthetically by a Multi-Room Expander and a Multi-Room Amplifier.
This combination forms a solution for all of your multi-room needs.
