Use of the DMM 4650

The DMM 4650 can be used in both, incorporated in a rack shelf system or as stand-alone unit. The installer should automate the daily sequences by external control keys, sensors, contacts and the corresponding unit settings. This applies for gongs, alarms, messages and their combinations, as well as for recordings of variable announcements. This contributes to a considerable advantage in the ease of use since manually operating the appliance is not necessary anymore.

Often used functions of the DMM 4650 are directly implemented as factory presets and can be utilized without any additional programming effort. By editing the default values and storing them into a user preset a customer-optimized configuration is quickly developed.

Audio function

The audio signals of the electro-acoustic sound reinforcement system are looped via INPUT and OUTPUT to the power amplifier. The SUM control can be programmed for this stand-by position. In case of failure a stand-by relay takes over the connection. When starting a sequence via control line, the desired audio signal gets generated (DMM SIGNAL) and fed to the OUTPUT via the programmable DMM-control. The controls (DMM, SUM) defined within the sequence determine, whether the two audio signals are merged or the one gains priority over the other.

The MIC, LINE input is used for recording a message and can also be used for announcement purposes. The headphones outputs PRE-LISTEN and PRE-OUT are for monitoring the DMM signals without actually starting a transmission.

Control function

A maximum of 16 floating inputs are provided for integration into a sound reinforcement installation. Their use and polarity can be freely programmed. A maximum of 16 floating relay contacts are provided to be used as control outputs. The inputs and outputs are divided into 4 Ports (A, B, C, D,); where Port A also contains a fault contact.
