Power Amplifier Automatic AC Switching & Installation
The Genesis System provides several built-in features, one of which is, the ability to easily
integrate an external power amplifier and have it automatically turn on when a specific room
is turned on. ADA recommends using the ACC-3 Low Voltage Triggered Switched AC Outlet.
The ACC-3 has two AC outlets which switch on and off together. The ACC-3 can handle a 15
Amp load.
The following diagram details the connection of the ACC-3 to the system such that it receives
a low voltage signal, emanating from the Genesis, when a specific room is turned on. This
signal is derived from pin #1 (ground) and pin #4 (+5VDC) on the control cable connector for
that room found on the back of the Genesis. The two conductor low voltage wire, going to the
ACC-3, is connected to these two pins in conjunction with the keypad's control cable.
Whenever that specific room is on, regardless of source selection, pin #4 is hot. This signal,
in turn, will cause the ACC-3's two AC outlets to turn on, and subsequently, the power amplifier
plugged into the ACC-3 (providing its power switch is left in the on position). When the room
turns off, the ACC-3 will turn the power amplifier off.
Please note, that when using an external power amplifier, you will want the Genesis to provide
a "variable' line-level audio signal to the amplifier. This variable line-level audio signal comes
off of the Genesis's "processor loop" output. Since the Genesis also uses this variable audio
s i g n a l
(preamplified
audio signal)
for its own in-
ternal ampli-
fier used for
other rooms,
you will need
to split the
p r o c e s s o r
loops output
to both the
e x t e r n a l
power ampli-
fier and the
G e n e s i s ' s
p r o c e s s o r
loop's input.
