Power connection
1
AC power connector and power indicator LED — Plug a standard IEC power
cord into this connector to connect the switcher to a 100 to 240VAC, 50 Hz or
60 Hz power source. The LED ( ) lights while the MLS is receiving power.
Input connections
2
Inputs 1–3 — For inputs 1, 2, and 3, connect a cable from the video source to
either (choose one)
• the BNC connector (composite video) or
• the 4-pin mini DIN connector (S-video ).
Input configuration is not needed for these inputs.
For audio input, wire the audio input connector as shown in the following
illustration.

Inputs 4–6 — For inputs 4, 5, and 6, connect a computer to the 15-pin HD
connector for RGB computer video input.
Each input’s audio source can be connected to either the female 3.5 mm mini
stereo jack (unbalanced input), or the 3.5 mm, 5-pole captive screw connector
(balanced or unbalanced input).
Wire the stereo jack audio input connectors as
shown at right. Wire the captive screw
connectors as shown above in

.
Video output connections
4
RGB computer video outputs — Connect a cable from the 15-pin HD
connector or the five BNC connectors to the projector for computer video
output from inputs 4–6. The output signal will be in the same format
(RGBHV, RGBS, RGsB, RsGsBs) as the input signal. The signal is switched,
but not processed. The two RGB video outputs (15-pin HD and BNC
connectors) are simultaneously active. Cables can be connected between the
projector and one, some, or all of the switcher’s video outputs.
Cable the BNC connectors according to the signal format as shown below.

S-video (Y/C) output — Connect a cable from these BNCs to the projector (Y/
luma on left, C/chroma on the right) for S-video output.
6
Composite video (Vid) output connector — Connect a cable from this BNC
connector to the projector for composite video output.
