System Mute
The System Mute component allows the entire system to be muted with a single mouse
click.
The System Mute component has no inputs or outputs.
The System Mute control window features only the SYSTEM MUTE button.
When the SYSTEM MUTE button is clicked, all the outputs of the entire DME32 sys-
tem, including the outputs of all DME32s in a multiple-unit system, are muted. All out-
puts are unmuted when the button is clicked again.
