Figure 3-1 — Three remote control options
1
Using the projector’s IR remote — For a projector with variable
audio outputs, use the projector’s IR remote to control the
projector’s volume, which effectively controls the MPA’s
volume.
2
Extron VCM 100 or mute controller — For a projector without
variable audio outputs, or for a system designed to control MPA
volume directly, use a 10k ohm potentiometer to control the
MPA directly via the remote port on the MPA.
3
Using a MediaLink™ Controller — For a projector with
variable audio output, use a MediaLink controller to control the
projector’s volume via RS-232 or the projector’s IR remote to
effectively control the MPA volume.
