Fig. 2
Using AC1's in a ZPR68-10 System
The Fig. 2 example works as follows:
• The Zone power amplifier (and other zone dedicated components, if used) is switched ON when a ZPR68-
10 INPUT command turns a zone ON [STATUS terminal goes high (+12V)].
• The Zone power amplifier (and other zone dedicated components, if used) is switched OFF when a
ZPR68-10 OFF command turns a zone OFF [STATUS terminal goes low (0V)].
• The Common Source components are switched ON when the first ZPR68-10 zone is turned ON [CO
terminal goes high (+12V)].
• The Common Source components are switched OFF when the last ZPR68-10 zone is turned OFF [CO
terminal goes low (0V)].
Another excellent application for the AC1 is to switch components that draw more power than is available
from the switched AC outlet on the rear of A/V receivers, preamps, etc. Fig. 3 illustrates such a system:
