MAV 128 RCA model

Inputs — These switchers offer 12 NTSC 3.58, NTSC 4.43, PAL, and SECAM composite video inputs on BNC connectors.

Unbalanced stereo audio is input on left and right RCA connectors.

Outputs — 4 or 8 composite video outputs are available on BNC connectors.

Unbalanced stereo audio is output on left and right RCA connectors.

Audio gain/attenuation — Users can set the input level of audio gain or attenuation (-15dB to +9dB) via the RS-232/RS-422 link or from the front panel. Individual input audio levels can be adjusted so there are no noticeable volume differences between sources (figure 1-5).

Figure 1-5 — Audio gain and attenuation

Audio follow — Audio can be switched with the corresponding video input, allowing any audio signal to be selected with any video signal simultaneously to one or all outputs in any combination. Audio follow switching can be done via front panel control or under RS-232/RS-422 remote.

Audio breakaway — Audio can be broken away from its corresponding video signal. Audio breakaway switching can be done via front panel control or under RS-232/RS-422 control.
