UDIOACCESS Important Safety Information The safety information in this summary is for installation and operating personnel. Warnings and cautions can also be found throughout the manual where they apply. CAUTION RISK OF ELECTRIC SHOCK DO NOT OPEN CAUTION: TO REDUCE THE RISK OF ELECTRICAL SHOCK, DO NOT REMOVE COVER (OR BACK).

Operating Environment For the best operating results, install the PX-603 in an area where it will not be exposed to direct sunlight or any heat source. The unit should be operated in a temperature range from 40˚...
• Inspect the shipping carton(s) for exterior damage before opening them. If any damage is discovered, notify your freight agent and Audioaccess immediately. • To open the shipping box, carefully cut through the packaging tape along the top edges and middle of the box, taking care not to cut through surrounding cardboard.

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.

UDIOACCESS Companion Products and Accessories The PX-603 is a Multi-Room Expander designed specifically to add up to three areas of inde- pendent volume control to any zone of an Audioaccess system. The PX-603 complements the PX-600 Multi-Room Preamp/Controller both functionally and aesthetically, and is visually identical to the PX-612 Multi-Room Amplifier.
KPT. Room Configurations (DIP settings) Each PX-603 room is associated with a zone, room and system via an 8 position DIP switch. Power Switch The POWER SWITCH turns the main power to the PX-603 on and off. Power Inlet The POWER INLET allows connection of the PX-603 to AC power via a standard IEC grounded power cord (included with 120 volt version).
Remote Control Remote Control PX-603 rooms share the source active in the PX-600 main room for the zone. When all rooms in a PX-600 zone are turned off, source selection for the zone defaults to TUNER (unless a room is still active and using a different source). The PX-600 Zone Output connected to the PX-603 Audio Input carries a constant, fixed line-level signal that is present as long as the PX-600 main power is on, whether or not the PX-600 main room is on.

• To un-mute the audio, press either the buttons. (Press MUTE again on the IR remote.) • To set PX-603 room turn-on volume: turn the room ON, adjust the volume to desired level, turn the room off, and within 5 seconds press simultaneously. The LED will flash to indicate acceptance of the new setting.
KP3s require six-conductor, 24 AWG wire and must be home-run directly to the PX-603. KPS keypads that will be used to control PX-603 rooms are not connected to the PX-603. They should be home-run to a KPT. Distribute KPSs evenly among KPTs to equalize electrical drain throughout the system, especially in multiple PX-600 systems.
Page 15
Home-Run Wiring Ideally, all KPS and PX-603 wiring should be home-run separately to one or more KPTs, then to the KEYPAD input on the PX-600 rear panel. This is the safest, most reliable method. Each KPS and PX-603 should be connected to a separate connector on the KPT. If you require more than six connections, use another KPT.
The KP3 IR receiver sends the IR information as electrical signals to the PX-603, where the signal is decoded as in the KPS. Control data is then sent to the PX-600. No actual IR signal is transmitted to the PX-600 from the KPS or KP3 keypad. If the func- tions of a repeater are needed, plan for the addition of a separate IR repeater next to the keypad or somewhere conveniently located in the room.
Page 17
DIP switches on the KPS address the room it controls - see page 12) The four wire bus labeled KPS is the communication link between the PX-600 Controller and PX-603 rooms. Connect it directly to the KPT. Do not make any KP3 connections with the PX-603 main power on; unpredictable system operation may occur.

The "Main Room" is always present in a zone; its room code is 0. Thus, a room code of 0 should never be set on the PX-603. For the first room added to a zone, the room code should be set to 1 (switch 4 up). For the second added room in a zone, set the code to 2 (switch 8 up).
EQ dip switch associated with that room to the "UP" or "ON" position. Power Cord (Grounding) Connect the AC power cord to the rear panel of the PX-603 and then to a properly grounded AC outlet. Make all of the remaining connections with the power cord plugged in (for grounding) and the AC power switch OFF.
Assign PX-600 zones to group A, B, C or N for none; PX-603 rooms may be selected to come on with the ALL-ON group or not. PX-603 rooms may not however, be assigned to a group independent of the main room.
Setting Turn-on Volume Turn-on volume for a PX-603 room is set at the KPS or KP3 keypad for that room. Start with the room off. Press the ON button, then adjust the volume level up or down to the desired turn-on volume.
PX-603 in single PX-600 systems. While we realize that PX-603s will be used in Multi-PX-600 systems, we expect that the primary application for the PX-603 will be to expand the scope of single PX-600 systems at a lower cost than multiple PX-600 systems. Keep in mind that the output of the PX-603 amplifiers is 22 watts with all channels driven.
The living room, being both a larger space and more likely to require higher listening levels, is the PX-600 main room, while the dining room and foyer are perfect applications for PX-603 rooms. Zone 6, the family room, is the heart of the home’s entertainment center. It is a multi-use room, with the home theater system and source equipment located in an easily accessible built-in cabinet.

To make the above diagram less cluttered, the PX-603 is shown separated from the PX-600 and PX-612. In the actual installation, all Audioaccess and source equipment should be located together. The PX-603 is not intended to be remotely installed away from the rest of the system.
DIP switches are set to reflect Zone 4, Room 1, System 0 (DIP switches 3 and 4 in the up position). The Zone Output of Zone 5, which has two PX-603 rooms assigned, is connected to Audio Input 2, and a jumper (14 mm staple variety or short RCA cable) is inserted from the loop-thru of Input 2 to Audio Input 3.
Diagram 4 Note: To make the above diagram less cluttered, the PX-603's are shown separated from the PX-600 and PX-612. In the actual installation, all Audioaccess and source equipment should be located together. The PX-603 is not intended to be remotely installed away from the rest of the system.
1 and 2 are configured for Zone 4, Rooms 1 and 2, System 0. The Zone Output of Zone 5 is connected to Audio Input 3 of the first PX-603, and is looped to Audio Input 3 of the second PX-603 with an RCA pair. Number 3 Room Configuration DIP switch sets of both PX-603s are set for Zone 5, Rooms 1 and 2, System 0.
Q: If I use two PX-603s, can I add two rooms to each of three zones? A: Yes. For one of the zones, hook the Zone Output to one Audio Input of each PX-603 and run an RCA jumper from the loop-thru of one PX-603 Audio Input to an Audio Input of the second PX-603.

(See page 16) Q: Will I be able to page into PX-603 rooms with a PDM? Can rooms be programmed for paging independently from the main room of the zone? A: Yes, paging is available in PX-603 rooms as long as the zone is programmed for paging.
• Be sure modular connectors are pushed in all the way on the PX-603 and KP3. • Ensure connectors are fully crimped. • Check location of modular plug on the PX-603 rear panel. Jack 1 controls the room assigned to Audio Input 1, jack 2 controls Audio Input 2’s room, etc.
