Turn off power to the MPS switcher and all other devices that will be connected.

If the MPS switcher is to be rack, table/wall, or through-desk mounted, position the brackets and insert the mounting screws. See the Mounting the Switcher, earlier in this chapter.

Attach up to four VGA, four S-video, and four video (composite) input devices to the MPS switcher.

Connect the switcher’s VGA, S-video, and video (composite) outputs (up to three, one of each video format) to a projector’s inputs.

For stereo audio input, connect up to 12 audio sources to the switcher’s audio inputs of the VGA, S-video, or video (composite) groups (up to four for each group). See the following Audio input and output section for connections.

For stereo output, connect an audio output device to each of the three groups and one audio amplifier to the Program Audio connectors. Refer to Audio input and output for wiring diagrams.

If the MPS switcher is to be connected to a computer or host controller for remote control, connect the host’s RS-232 cable to the 9-pin female RS-232 connector of the MPS unit. For an RS-232 pinout table, see Remote connection later in this chapter.
