5.2 A 4493 MUSIC SOURCE SELECTOR WALL PLATE
The A 4493 wall plate allows remote selection of the A 4480B’s zone’s input audio source and volume level.
In addition, when connected to the A 4931 local zone input wallplate, it allows the use of a local signal source, such as a
wired mic, radio mic or aux source such as a mobile device, which VOX mutes the selected input from the A 4480B.
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 4480B Audio Switcher will override these volume settings.
