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, the BGM level on that LOCAL PA OUTPUT is dropped to a
half-muted level and the PA audio is mixed into it. 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 re-
spond 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 sixteen trunk lines that 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 DR-3000 can be configured to respond to up to sixteen differ-
ent PA ZONE requests (eight per side). Any number of DR-3000s can be configured to respond to any in-
dividual PA ZONE request. This allows a PA ZONE to be assigned as a global PA ZONE by simply telling all
the DR-3000s in the system to respond to it. The priority of PA requests is set by the order in which they
are entered when configuring the DR-3000.
DUMB PA STATIONS are available with either four buttons (plus the microphone button) or one button
(just the microphone button). Any of the buttons can be configured to access any PA zone in the sys-
tem. The buttons on the front of the four button stations can be configured as push-to-talk buttons, to
latch the last requested zone, or auto-release the last zone latched when the microphone button is re-
leased.
For automated PA announcements, a phantom PA station is used. It is like any other PA STATION ex-
cept that it has no buttons or microphone on it. The audio and status outputs from a AB/DR-3000 is at-
tached to the phantom PA station. When the Repeater is started, the status output triggers the phantom
PA station to request a PA ZONE and then feeds its audio into it. The audio will then be routed to the ap-
propriate audio outputs through the PA system just like any other announcement. Different spiels can
