Installation
Step 1 — Disconnect power
Turn off or disconnect all equipment power sources.
Step 2 — Mount the unit
Select a mounting option and install the appropriate brackets. Mount the switcher.
Step 3 — Connect video inputs
Attach up to four VGA, four S-video, and four Video (composite) input devices to the MPS switcher.
Step 4 — Connect video outputs
Connect a VGA output, an S-video output, and a Video (composite) output from the switcher to the appropriate projector inputs.
Step 5 — Connect audio inputs
For stereo input, connect up to 12 audio sources to the audio inputs of the VGA, S-video, or Video (composite) groups (up to
four audio sources for each group). Stereo audio in the VGA group is input via standard 3.5mm stereo mini connectors. Stereo
or mono audio in the Video and S-Video groups are input on standard female RCA connector pairs.
Step 6 — Connect Mic input
If a microphone is required, connect it to the 1/4" connector on the
MPS 112 or the 3-pole, 3.5mm captive screw connector on the MPS 112CS,
as shown.
Step 7 — Connect audio outputs
For stereo audio output, connect an audio output device to each of the three output groups. Connect an audio amplifier to the
Program Audio output connectors (female RCA connectors on the MPS 112, 3.5mm captive screw connectors on the MPS 112CS).
This guide provides basic instructions for an experienced installer to set up
and operate the Extron MPS 112/112CS media switcher.
