Madrigal Imaging PX-600 - Manual (Page 3)

Thank you for choosing the Audioaccess PX-600
Multi-Room Preamp/Controller.
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.
You can turn zones on or off, select sources,
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.
Your PX-600 was configured by your authorized
Audioaccess dealer at the time of installation.
Programmable features include the turn-on volume,
maximum volume, lockout, bass and treble settings
for each zone, group set-up, paging setup, and spe-
cific IR protocols for tuners, CD players, high-capac-
ity CD changers, tape players and VCR’s, as well as
special macro commands tailored for control of
popular surround processors.
