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

Introduction, cont’d All models Bandwidth — Bandwidth is 350 MHz (-3 dB). This high bandwidth allows the switchers to switch all of the high-resolution video signals with no loss of signal quality. Input signal sensing — The switcher continuously monitors all inputs to sense when the input signal is active or inactive. The switcher reports changes in the status of each input (active to inactive or inactive to active) on the RS-232 port. Autoswitching mode — When autoswitching is enabled, the s
