Overview
The A 4491and A 4492 wall plates allow remote selection of the zone's input audio source and volume level.
In addition, when connected to the A 4478 or A 4479 local zone input wallplate, it allows the use of a local signal source,
such as a wired mic, radio mic or aux source, which VOX mutes the selected input from the A 4480.
The LCD displays the zone name, the input sources and zone and local input volume levels.
Note: The volume controls only adjust the volume of the 8 aux input sources, plus the local input (when used).
General and emergency paging from the A 4480 Audio Switcher will override these volume settings.
