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.
