The DSP-based system MAGIC DABMUX plus Encoder Edition allows the encoding of up to 14 DAB+ programmes in a 19“ x 1 U unit. For the feed of PAD (Program Associated Data), a PAD inserter is integrated for each encoder, which allows an easy input of Dynamic Labels (DLS / DLS+) and Slideshows (SLS / categorised SLS). The insertion of additional information can be done via FTP or via a modern JSON/XML based API.

The system is synchronised either via NTP or, when AES67 is used, via PTPv2.

For encoding, the DAB+ encoder developed and licensed by the Fraunhofer Gesellschaft is used. This offers the best possible audio quality – even at low data rates.

Each DAB+ encoder can be licensed individually, so the system can be easily expanded for newly added programmes.

Audio input & monitoring output

Audio input is achieved either via AoIP AES67 streams or as Icecast/SHOUTcast web streams (MP3 or FLAC format, 16 bit, 48 kHz).

If AES67 is used, two AES67 stereo outputs (4 channels) are automatically available for monitoring purposes. Via the HTML5 web interface, any programme can be conveniently selected and monitored via AES67.

Encoder output

The output signal can be sent to up to two locations as a simulcast stream via unicast or multicast.
The output format EDI(ETI), EDI(STI-D) or AVTMUX can be set individually for each programme.

In addition to the separate programme output signals, an output in EDI(ETI) or EDI(STI-D) format is available to transport all programme contents of the system in a common data stream.
