Features

Audio switching models

Inputs — These switchers input 2, 4, or 6 stereo audio signals, balanced or unbalanced, on 3.5 mm, 5-pole captive screw terminals.

Outputs — The selected audio input is buffered and output, balanced or unbalanced, on a 3.5 mm, 5-pole captive screw terminal.

Audio gain/attenuation — Users can set the input level of audio gain or attenuation (-18 dB to +24 dB) via the RS-232 link or from the front panel, to be compatible with a wide range of line level (from -20 dBV to +4 dBV). Individual input audio levels can be adjusted so there are no noticeable volume differences between sources (figure 1-2) and for the best headroom and signal-to-noise ratio. This function also eliminates the need for separate preamps or attenuators when used with professional (higher line level) and consumer (lower line level) audio equipment.

Audio follow — Audio can be switched with the corresponding video input. Audio follow switching can be done via front panel control or under RS-232 remote control.

Audio breakaway — Audio can be broken away from its corresponding video input signal. Audio breakaway switching can only be commanded under RS-232 remote control.
