Details

DAR is a professional DVB-S/-S2/-C audio receiver designed for the reception of audio data and accompanying ancillary data. It comprises a DVB satellite tuner with MPEG audio decoder and a demultiplexer for the retrieval of ancillary data. DAR can be used e.g. for feeding data to terrestrial FM transmitters (main or standby), where user specific additional data like e.g. RDS are needed beside the audio signal. DAR provides undecoded MPEG audio data feed for DAB transmitters. Data feed for DVB networks is provided by the optional ASI interface.

DAR is available for both DVB-S/-S2 and DVB-C.

The sampling rate of the digital audio output can be synchronised to an external clock connected to the sync input.

For signalling alarm status DAR has 4 dry relay contacts (change-over contacts).

Locally DAR can be controlled by using the built-in key panel and display. Remotely the device can be controlled by accessing the on-system web server with any internet browser or by SNMP, which is a standard feature.

As an option the DVB-ASI interface of the DAR can be replaced by a second tuner (DVB-S/-S2 or DVB-C).
