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

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.
