Thank you for choosing the Audioaccess PX-600  
Multi-Room Preamp/Controller.  
You can turn zones on or off, select sources,  
17 38" W x 4" H x 15" D  
(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-600s 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-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.

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.
