PA Interface Cards

Eight LOCAL PA OUTPUTS are available from each MA-100 or MA-200 card. Each of these outputs nor-

mally carries whatever audio is being fed into the ÔBack Ground Music (BGM) inputÕ on the back of the
unit. When a request for a PA zone comes in from any of the PA STATIONS, the BGM level on any of the
LOCAL PA OUTPUTS is dropped to a half-muted level on those LOCAL PA OUTPUTS which are responding
and the PA audio is mixed into the output. All audio levels and settings for the LOCAL PA OUTPUTS are
adjusted through the software on the MA-100 PA Master. Each LOCAL PA OUTPUT can be told to respond
to up to four different PA zone requests. If the PA STATION requesting the LOCAL PA OUTPUT has the same
ÔnumberÕ as the output being requested, a special ÔLOCAL PA MODE can be used as shown above. This
bypasses the 16 trunk lines which normally carry the PA audio feeds to allow up to 256 such PA
announcements to go on at the same time.

There are 256 possible PA ZONES. Any Digital Audio Repeater / Mixer card can be configured to

respond to up to eight different PA ZONE requests. Any number of cards can be configured to respond
to any individual PA ZONE request. This allows a PA ZONE to be assigned as a global PA ZONE by simply
