Figure 3-1 — Remote Control Options
a
Using the projector's IR remote — For a projector with variable
audio outputs, connect the projector audio output to the
MPA 152 audio input. Use the projector's IR remote to control
the projector's volume, which effectively controls the volume of
the MPA 152.
b
Extron VCM 100 AAP volume and mute control — There are a
variety of options for a projector without variable audio outputs,
or for a system designed to control MPA 152 volume directly.
See page 2-12 for more information.
c
Using a MediaLink
™
Controller — For a projector with variable
audio output, connect the projector audio output to the
MPA 152 audio input. Use a MediaLink controller to adjust
the projector's volume via RS-232. MediaLink controllers can
also use IR remote to adjust the projector's volume and thus the
input to the amplier.
