Using the 12V Triggers

The 12V triggers A, B, and C can be used to turn on 12V
trigger-capable components automatically when they are
selected as the input source. The triggers can be set so
that they activate when a connected component is
selected as the input source for the main room, Zone 2 or
any combination of rooms. When triggered, the output
from a 12V TRIGGER OUT goes high (+12 volts and
150 milliamperes max. at 12V TRIGGER OUT A; +12
volts and 25 milliamperes max. at 12V TRIGGER OUT
B and C).
Hookup
• Use a mini plug cable to connect the receiver's 12V
TRIGGER OUT A, B, or C jack to the 12V trigger
input on a connected component.
When several components are turned on simultaneously
by using triggers A, B, and C, depending on the type of
components, a large amount of current may be drawn
momentarily. To prevent this, you can delay trigger
signals A, B, and C individually. Another application of
trigger delay is eliminating the "thump" noise that's
sometimes heard when a source component is turned on.
You can accomplish this by delaying the trigger signal
for your power amplifier, so that it's the last component
to be turned on.
