Thank you for choosing the Audioaccess PX-600
Multi-Room Preamp/Controller.
You can turn zones on or off, select sources,

(442 mm x 102 mm x 381 mm)
Includes connectors and feet
control their basic functions, and change volume
independently in each zone, just by the touch of
a single button on the 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 hand-held 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.
Control of basic source functions (i.e. play, skip
track, skip disc, skip preset, fast forward, etc.)
And congratulations. Your new unit is an excep-
tionally well-engineered product that will give you
years of superb performance.

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 key-
pads 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-600’s 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.

SYSTEM
OPERATION
SPECIFICATIONS
The Audioaccess PX-600 keypads, front panel and
IR remote controls are designed for simple, intuitive
system operation. You will not need lengthy training
or a full understanding of audio/video systems to
master the operation of your PX-600 system. Use
the following outline (which focuses on the opera-
tion from the keypad) and experiment. Check with
your dealer to find out about any special or alternate
features that may have been installed for you. You’ll
soon be an expert!
L
To turn off all zones in the system, as well
as the power to the source components,
regardless of ALL ON grouping, go to any
keypad, make sure it is ON, then press-and-
hold the ON button for about two seconds
or until the ON LED flashes on a keypad. All
zones will turn off. (The front panel has a
separate ALL OFF button.)

Certain options are available that affect the opera-
tion of ALL ON. For example, if your system is
programmed with the TIMEOUT feature, the zones in
an ALL ON group may be set up to revert back to
independent operation 30 seconds after the ALL ON
is initiated. If this is the case, momentarily pressing
the ON button will only turn off the zone you’re in.
Check with your dealer for further information.
