1-3SW RGB and YUV A Switchers • Introduction
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.
