Promote Your Business While
Customers Hold!
The DVA-2W is a digital record and announce
device with a built in 2 watt amplifier. Designed
to provide music and promotion on hold, the
DVA-2W can playback in a continuous loop or
alternate between promotions and an auxiliary
music source at 15 to 60 second intervals. Any
number of multiple promotion messages may
be recorded.
The output of the DVA-2W may also be connected directly to loudspeakers and played
at the push of a button for museum displays, information booths, point of interest
locations, etc.
The DVA-2W's non-volatile E memory eliminates the need for batteries or costly built
in tape decks. This provides the convenience of recording at the shop or professional
studio and then shipping to the installation site.
