Dealer/Manufacturer Questions and Answers
At Audioaccess, we believe our dealers are an integral part of our marketing, design and
manufacturing team. The PX-603 is a direct product response to requests from dealers for
a cost-effective way to expand multi-room systems without having to use remote amps and
autoformers. These are real questions that have come up in conversations between custom
installation system designers and installers and various Audioaccess staff members prior to the
release of the PX-603. The answers come directly from members of our Technical Support
and Engineering Departments.
Q: What is the difference between a zone and a room?
A: A zone is an area of independent source selection made up of one or more rooms. A room
is a physical area of independent on/off and volume control within a zone.
(See page 16)
Q: How many rooms can I add to a PX-600 zone with a PX-603?
A: Up to three PX-603 rooms, for a total of four rooms in any zone.
(See page 2)
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. Configure the DIP switch settings accordingly.
(See diagram 5, page 21)
Q: Can my client select sources from a PX-603 room?
A: Yes, using either a KPS keypad or a KP3 with an RT-A or URC-8090 IR remote, but
remember that source selection affects all rooms in the zone.
(See page 2)
Q: What signal is coming through the PX-600 Zone Output?
A: Line-level signal from the source selected in the zone or TUNER if the PX-600 main room
is not on. The source selected for the zone may be changed once any room is turned on.
(See page 2 and page 6)
Q: Can I use the Audio Input loop-thru to drive another amplifier and still take advantage
of the PX-603 as volume control?
A: No. The loop-thru carries the same fixed line-level signal as the Zone Output of the
PX-600. No volume regulation occurs in the Audio Input stage.
Q: How many KPS keypads can I use in a System?
A: The maximum number of KPS keypads is 20 per PX-600. The addition of PX-603s does
not affect this maximum.
