5.0 Reticulated IR
Multi Room Audio Amplifiers can distribute infrared (IR) remote control
signals through to a Matrix Switcher or Distribution Unit. IR is received by
IR Targets installed in a wall or ceiling, or plugged directly into a Desktop
Amplifier (refer to
Figure 9). IR is distributed to Emitters which are plugged
into th
e Matrix Switcher or Distribution Unit, and positioned over the IR
receiver of the audio source equipment.
If reticulated IR has been included in your MRA system, you can control
your source equipment (such as a CD Player and TV) from any room which
is fitted with an MRA IR Target. Simply point the source equipment’s IR
remote control at an IR Target.

6.0 Using Headphones
The MRA Desktop Amplifier has a 3.5 mm stereo headphone socket on its
rear panel. This allows you to listen to audio through headphones. In some
installations the headphone output may be connected to a wall plate,
possibly together with local inputs.
Set the volume to a low level before connecting headphones. Once you
have plugged headphones into the Amplifier (either via a wall plate socket
or directly into the Amplifier), press the Mute button for more than 400 ms
to silence the speakers. Refer to Mute in Section 4.2 (Page
11).
