MLS 406, MLS 406MA, and MLS 406SA Rear Panel

NThe MA and SA models differ only by amplifier output type and connection. All other A/V, power, and control connections are the same.

Power connection

A	AC power connector — Plug a standard IEC power cord into this connector to
	connect the switcher to a 100 to 240 VAC, 50 Hz or 60 Hz power source.
	The front panel power LED ( ) lights while the MLS is receiving power.

A/V input connections

BBVideo inputs —

MLS 304MA MLS 304SA: connect a composite video source device to each of these female RCA (tip-ring) connectors for video inputs 1 and 2.

MLS 406, MLS 406MA, MLS 406SA: connect either an S-video source (using the 4-pin mini DIN connector) or a composite video source (using the BNC connector) for input 1, 2, or 3.

ÑRCA audio inputs — These audio inputs correspond to the like-numbered video inputs. These inputs accept line level audio signals from consumer and professional audio sources. Consumer devices such as PCs, VCRs, and DVD players typically output an unbalanced ‑20 dBV to ‑10 dBVsignal. Professional products such as mixers and signal processing gear typically output a balanced 0 dBu to +4 dBu (+6 dBV) level signal.

To adjust input levels, see pages 3‑5 and 4‑10 through 4‑11.

Connect an unbalanced stereo audio source to each pair of RCA jacks. Use the red sheathed cable/connector for the right channel, and use the white

sheathed cable/connector for the left channel as shown below.

Wiring RCA connectors for unbalanced stereo audio input

NAfter the audio inputs and outputs are connected, see chapter 3 for instructions on how to adjust the per-input audio input levels and optimize audio input and output.
