Audio follow — If the switcher is also a video model, 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 — If the switcher is also a video model, audio can be broken away from its corresponding video input signal. Audio breakaway switching can be done via front panel control or under RS-232 remote control. Executive mode (front panel security lockout)— All switchers that route audi
