System Design

Particular suggestions for system design have come from our most successful dealers. Guide-

lines for setting up Audioaccess systems can be found in the System Design portion of the

PX-600 Installation Manual. Please refer to this section; we believe you’ll gain some important

benefits from these general practices.

Designing systems to include the PX-603 requires clarification of two terms used in discussing

Multi-Room systems. The critical concepts that must remain separate in the designer’s mind

are zone and room. ROOM means an independent area of volume control within a zone.

ZONE means a room or group of rooms with independent source selection. In the past, we

tended to use these terms interchangeably, which led to confusion. The rooms connected to

the PX-600 controller are the main rooms of each zone and have control of the source selected

for all rooms in that zone. PX-603 rooms have independent on/off and volume control, and

source selection can be made from them via IR and/or keypads, but they cannot select sources

independently from the main room.

The following pages contain simple block diagrams depicting applications for use of the

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. This makes it perfect for

adding music in small rooms, hallways, porticoes and the like, or background music in rooms

designed for social settings, but may not be sufficient in larger rooms or open outdoor areas.

Furthermore, PX-603 rooms assigned to Zone Six, the main zone, are likely to have a slower

keypad response time than PX-603 rooms in other zones due to extended IR functions which

take place in that zone.
