Requirements for the MLC 52 VC
To set up a system that contains an MLC 52 VC model and an Extron MPA power
amplifier, an MP Series preamplifier, or a PoleVault PVS switcher, you must ensure that the
following conditions are met:
• The projector must have dedicated video and audio inputs for each source used in
the system.
• The projector must have a switched audio output. On most projectors, this connector
is labeled as “Monitor Output” or “Audio Output” (see figure 20 on the next page).
With a switched audio output, the projector outputs the audio from the selected video
source.
• The system must incorporate an Extron device.
