IR Remote Control Connections
Since the Maestro is often hidden away in some dark
closet or equipment rack, we have provided connections
for external IR remote control receivers and emitters. This
allows you to place the infrared receiver where it can “see”
the signal from the remote control. The Zone 2 IR input
controls the second zone functions of the Maestro and also
repeats commands to the source units through the emitter
output.
The IR receiver input connections are wired with a 3
conductor 3.5mm jack. The signals are compatible with
third-party receivers such as a Xantech No. 291-10.
AudioControl does not supply the IR receivers or emitters
to use with the Maestro.

12V Trigger Connections
There are three mini-jack 12 volt trigger outputs on the
rear panel of the Maestro. These are used to remotely
control such things as the power amplifier turn-on, projec-
tor power, screens or curtains. The System Trigger Jack has
two separate outputs. The jack is a three conductor; Tip,
Ring, Sleeve, connection.

The other two trigger outputs carry one signal each. The
Main Trigger connection has 12 volts DC when the Maestro
is turned on. The Video Trigger jack goes to 12 volts when
one of the video sources is selected.

The Main Trigger would generally be used to control the
power to the amplifiers and source units. The Video Trigger
would be used to control the projector or video screen.
