Mute control
The mute control provides a way to mute individual outputs, or all outputs at once. Audio and video for each output are muted simultaneously.
Each output is assigned to a pin on the captive screw connector. To mute any output, short its pin to the ground pin (
). Multiple outputs can be shorted at the same time. To mute all outputs at once, short pin A (all) to the ground pin.
