MLS 406, MLS 406MA, MLS 406SA audio input 4 (captive screw) — This
input accepts line level audio signals from consumer and professional audio
sources. Consumer devices such as laptops, VCRs, and DVD players typically
output an unbalanced -20 dBV to -10 dBV signal. Professional products such
as mixers and signal processing gear typically output a balanced +4 dBu level
signal. To adjust input levels, see pages 3-5 and 4-10 through 4-11.
Wire the 3.5 mm captive screw connector as shown in the
following illustrations, depending on input signal type.

optimize audio input and output.
Computer video (and audio) inputs — MLS 304MA and MLS 304SA inputs
3 and 4; and MLS 406, MLS 406MA, and MLS 406SA inputs 4, 5, and 6, all on
15-pin HD connectors; are individually buffered and provide ID bit
termination. They accept
• RGB computer video signals (default) or
• S-video (MLS 406 Series only) or composite video (all models)
For S-video or composite video, the switcher must be configured via RS-232
serial control (SIS commands or control software); see pages 4-4 and 4-10
through 4-11.
For RGB input, connect a standard VGA-style cable from the source computer
to the desired MLS input. For S-video or composite video input, you may
need to use an adapter cable such as an Extron SY 15HDM-RGBHV cable
(shown below). Connect the video or S-video source to the MLS as follows:
N Selecting S-video or composite video for these inputs limits the Monitor
Output mode options to Standard Mode.

• If the stripped section of wire is
longer than 0.2", the exposed
wires may touch, causing a
short circuit between them.
• If the stripped section of wire is
shorter than 0.2", wires can be
easily pulled out even if tightly
fastened by the captive screws.
