Description
The DMM 4650 is a signal processor which allows for an universal generation and control of audio signals. Its main
purpose is the installation in electro-acoustic rack systems, but stand-alone applications are possible as well. The
audio signals can consist of alarm, gong, voice messages but also of random combinations of these sources. The pro-
grams were created by Dynacord (preset). Anyway, it is possible for the user (consulting company, etc.) to modify tho-
se programs and store them as user-programs. The audio input can be mixed with the DMM 4650 internally generated
audio signals (e.g. gong signals with announcements), or given out as priority at the audio output (programmable).
The audio quality of the messages can be selected, depending on memory extension and different user requirements.
With maximum memory extension, a total recording time of 16 minutes is possible. Password protection for various
operation levels is provided. For “EASY-USER”, the provided operation features are similar to those known from cas-
sette recorders or CD players. The control of the programs is performed via fl oating inputs and fl oating outputs provide
status messages. The priorities and functions of these lines can be programmed individually (Setup). A computer inter-
face facilitates saving and loading of the unit’s confi guration and its message data.
In order to ensure functional reliability, self-surveillance and audio data verifi cation are employed. The alarm is ignited
via internal fault-output while all warnings are logged. The DMM 4650 is maintenance-free since no serviceable parts,
batteries or accumulators are to be found inside the appliance.
