Technical Information
Description
The DMM 4650 is a signal processor, allowing an universal generation and
control of audio signals. The main application is for PA racks, but stand-
alone applications are possible as well. The audio signals can consist of
alarm, gong, messages and also random combinations. These programs
were created by Dynacord and stored as presets.
The audio quality of the messages can be selected depending on memory
extension and different user requirements. With maximum memory exten-
sion, a total recording time of 16 minutes is possible. Password protection
is provided. The operation is easy, like cassette recorders or CD players.
A computer interface allows saving and loading of unit confi gurations and
message data.
In order to ensure function reliability, a self-test and a audio data verifi cati-
on is installed. The alarm takes place via an own output "Fault/Error". The
device is maintenance-free because no battery or accumulator is installed.
Installation instructions
The appliance must be protected against:
- drip or splashwater
- direct sun irradiation
- high ambient temperature or direct infl uence of heat sources
- high air humidity
- heavy dust deposits
- strong vibrations
If the unit is brought directly from a cold to a warm place, dampness can
precipitate on the inner parts. The unit may only be put into operation after
it has warmed up to the ambient temperature (approx. after one hour).
Should an object or liquid get into the case, disconnect the unit from
the current sources immediately and have the device checked by a
DYNACORD service center, before further use.
Do not use any sprays to clean the unit, as these can damage it, perhaps
causing it to ignite suddenly.
