Recorded message manager

Summary & Images Specs Downloads & Support

The DMM 4650 is a digital audio storage system, capable of audio recording and playback, as well as, audio signal generation such as alarms. The main application is as an additional audio recording device for the ProAnnounce system, 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 extension, 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 configurations and message data.

In order to ensure function reliability, a self-test and an audio data verification is installed. The alarm is provided via a dedicated output. The DMM 4650 does not require maintenance due to its use of flash memory.
