The DVA-2WA is a digital announcer with a built in 2 watt
amplifier. Designed to provide music and promotion on
hold, the DVA-2WA can playback in a continuous loop or
alternate between promotions and an auxiliary music
source in timed intervals. Any number of multiple mes-
sages may be recorded.
The announcer comes with four professionally pre-recorded
promotion on hold messages, a power supply and cabling
for an easy plug and play installation.
The output of the DVA-2WA may also be connected directly to loudspeakers for repeated mes-
sages or played at the push of a button for museum displays, information booths, point of inter-
est locations, retail applications, etc.
The DVA-2WA’s non-volatile memory eliminates the need for batteries or costly built in tape
decks. This provides the conven-
ience of recording at the shop or pro-
fessional studio and then shipping to
• On-hold promotion messages and background-music
the installation site.

4. Multiple Units with I.O. (Input/Output) Communication
When installing multiple DVA-2WA’s in displays that are close enough together to cause audible interference, the
I.O. communication will allow only one DVA-2WA to announce at a time. The last unit to be triggered will announce
its message, disabling any current messages played from any previously triggered DVA-2WA.
a. Connect speakers and remote momentary switches to DVA-2WAs as shown in sections 1, 2 or 3 above.
b. Connect I.O. Com connections as shown to prevent two announcers from playing at one time.
c. A remote ”stop” switch can be connected to I.O Connections A & B. A momentary closure will stop message.

Operation
A. Recording
The DVA-2WA is designed to be recorded from any line level source (tape/CD player, PC soundcard, etc.) or live from
an Electret microphone or carbon handset. Single or multiple messages may be recorded. There is no defined limit
(other than maximum record time) to the total number of messages which can be recorded. With the PLAY/RECORD
switch in the RECORD (right) position follow the steps in Programming and Recording.
B. Information On-Demand
With the PLAY/RECORD switch in the PLAY position, the DVA-2WA is ready to play. Momentarily press the start
switch on the front panel or a remote switch connected to the remote trigger terminals (or “REMOTE SW” pads 1 & 2)
to initiate a single message playback. Each message will playback one at a time in the order in which they were
recorded. After a message has been played, the button must be pressed again for the next message. The START/
STOP switch on the front panel (or the switch connected to “REMOTE SW” pads 1 & 2) can also be used to start and
stop message playback. Momentarily pressing the switch during an announcement will stop playback and will also
reset the unit to begin playback from the first message recorded on the next switch activation or remote trigger.
C. Continuous Loop
In the continuous loop mode (see Installation section C), the DVA-2WA will play all recorded messages one at a time
in the order in which they were recorded with programmed delay times between each message. Delays between mes-
sage playback are selectable from 2 seconds to 30 minute increments (see Programming section C). If a background
music source is connected, music will be faded in and out during the delay times.
Note: If the Auxiliary Audio is not loud enough, and the AUX AUDIO is at maximum, increase the volume of your
music source (licensed radio, etc.)
