PA Interface Cards
As shown by the darkened audio path in the above illustration, when a user at any PA station
requests a PA ZONE, an audio path is opened to any of the Local PA Outputs and DIGITAL REPEATER /
MIXER cards in the system which have been configured to respond to requests for that PA ZONE (in this
example there are three DR-300 or DR-400 cards and four Local PA Outputs responding). The normal
audio on those outputs is dropped to the half muted level (this level is adjustable on each output) while
the audio from the PA station is routed to the outputs (the volume of the announcement is also
adjustable on each output). The rest of the audio system and the Repeaters on the affected DR-300
