tape for use during programming 16 . This is done by using the repeater as both the audio source and
SMPTE generator. You can then program the show normally with absolute assurance that the final audio
and time code will be perfectly in sync.
The SMPTE time code input on each AB/DR-3000 can listen to a SMPTE time code signal and trigger
spiels on the left or right side of the repeater. Once triggered, the repeater will NOT follow variations in
the SMPTE time code input. The table of SMPTE trigger points holds up to forty-eight different entries.
Triggering resolution is down to a single frame, but only one spiel can be triggered during a single sec-
ond. The AB/DR-3000 needs to have been listening to time code long enough to receive the beginning
of the second before the trigger. This means that if the time code is starting at 00:00:00.01, that no spiel
can be triggered before 00:00:02.00. The AB/DR-3000s should accept SMPTE time code within 25% of
30 Hz which is recorded with 24, 25, 30 or 29.97 Frames Per Second. The time code can be either Drop
or non-Drop frame. The only thing you have to do is not to ask the AB/DR-3000 to trigger on a frame
which doesnÕt exist in the incoming frame rate. i.e.: If you are using SMPTE at 25 FPS, donÕt try to trigger
sounds on the 26th frame.

The Intelligent Public Address System is used where a powerful and flexible zoned Public Address
System is needed. It can be used with our DR-3000 and DR-4000 Digital Audio Repeater cards or in
stand alone installations. Complete information on the Intelligent Public Address System can be found in
its manual.
The Intelligent Public Address System features include:
¥ Up to 255 PA zones are available. Sixteen cross-zone announcements can be made at one
time, along with any number of local PA zone requests. These latter take place when any PA
station requests itÕs local PA output.
¥ Supports up to 256 PA stations. These are available in:
a) One Button PA Stations use the microphoneÕs Push To Talk (PTT) button to select any one
of the PA zones.
b) The Four Button PA stations can select any of four different PA zones, plus one more with
the microphoneÕs PTT button. You can tell the buttons on these stations to latch the zone
requested, only momentarily select the zone, or latch it until the next time the PTT button
is released. Any of the four buttons can also be configured to raise or lower the volume
or mute and unmute an area.
c) The Smart PA stations can be set up to access all the features in the entire audio system.
These include any Digital Audio Repeaters, Animation Control Systems, and volume con-
trol zones that happen to be attached to it. They are available with backlit LCD displays
on them. Their pushbuttons are normally located on the microphone itself, or any DTMF
keypad can be used.
d) Phantom PA Stations are used to tie the output from Digital Audio Repeater to the PA sys-
tem for automated announcements. When the Repeater is triggered, it will select a PA
zone and feed the audio output from the repeater to the selected zone.
¥ All setup is done through easy to use menus using any PC or terminal. Configuration includes
selecting which zones any PA station button will select, and the normal, half-muted, and PA
announcement volumes for the local PA outputs. A key lock and battery protects the configu-
ration data from unauthorized access and power failure.
¥ Separate printer and terminal outputs can give a running record of all PA system activity.
¥ PA Master controls up to eight volume zones, or any other 0 to 10 VDC controlled device
(lights, screens, etc.).
¥ Eight PA stations per Interface Panel. Stations are transformer and opto isolated from the rest of
the system.
¥ Wiring to all PA stations is by standard 8 conductor modular telephone line. Power for the sta-
