The MAGIC AE4 DAB/DAB+ Encoder offers in the standard version one DAB/DAB+ hardware encoder and can be optionally upgraded with three further encoders. Each of the four channels are independent and can be configured independently as a DAB or DAB+ encoder. The system is realized in a compact, fanless and DSP-based design. The audio programs can be supplied via the four digital AES/EBU stereo interfaces. An analogue stereo interface is also available.
The PAD is usually fed in via the Ensemble Multiplexer, which scans the PAD via the return path of the transmission protocol on the encoder. All PAD services supported by the multiplexer can be used.
In addition to PAD, service information such as the Program Type (PTy) and Traffic Announcement (TA) can also be transmitted via UECP for each program. The triggering of a traffic announcement can be easily implemented via a TTL contact.
As transmission protocols with reconfiguration capability and PAD insertion, the system supports the proprietary standards AVTMUX, FhG MuxEnc, AVTVDL and ODR DabMux.
The EDI (ETI) standard also allows the system to be connected to almost any Ensemble Multiplexer from other manufacturers. In this case, however, reconfiguration and PAD feeding from the multiplexer is not possible, since EDI cannot transfer control information.
