INSTALLATION INSTRUCTIONS
AC1
DC CONTROLLED SWITCHED AC OUTLET
The AC1 is a DC voltage controlled AC outlet, capable of switching up to 15 Amperes of continuous current
to a device or power strip. It is intended primarily to provide common and zone AC power management in
conjunction with the CO & STATUS ports of the ZPR68 and ZPR68-10. It is usable, however, in any
application where it is desired to have an AC outlet turned on and off by a DC control voltage.

INSTALLATION
The AC1 provides a convenient means to manage the power ON/OFF status of "Power Line Switchable"
components in a ZPR68-10 multi-zone system. Typical connections are shown in Fig. 2.
"Power Line Switchable" components are those that have manual power switches that can be left "ON" or
those that "remember" their "ON" condition when their power cords are unplugged.

The Fig. 2 example works as follows:
• The Zone power amplifier (and other zone dedicated components, if used) is switched ON when a ZPR6810 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:
