Hardware Multiplexer for basic DAB Multiples

MAGIC DABMUX Go RF is the world’s smallest and only DSP-based ensemble multiplexer, and thus offers high availability with excellent performance. With MAGIC DABMUX Go RF RM it is now available as a 19″ version that can be mounted in a rack.

Up to 20 program providers can be connected via external audio encoders. Installing the encoders directly in the studio effectively prevents the audio quality from being impaired by codec cascades.

Particular importance was attached to the simple configuration of the ensemble multiplexer using a web browser, so that users without DAB expert knowledge can also set up the system.

The highly compact DAB ensemble multiplexers enable very simple multiplexing according to the ETSI EN 300 401 standard. Despite its size, features such as reconfigurations (manual and time-controlled), extracting sub-channels from other multiplexers, inserting PAD and NPAD data services, generating service information etc. integrated.

Either the AVTMUX protocol or EDI(ETI) from external multiplexers is expected as the input signal. Both multiplexer variants deliver an EDI signal as an output signal for transmission to the transmitter locations. Alternatively, a power output stage can also be controlled directly. This possibility is particularly interesting if only one transmitter location exists.

The synchronization takes place either via NTP or via the integrated GPS receiver.

Configuration, operation, and monitoring is carried out via an HTML5-capable web browser.

Of course, an external alarm can also be sent via SNMP.

In terms of network technology, the system has a GBit Ethernet interface that allows you to set up to three IP addresses and VLANs.

MAGIC DABMUX plus Upgrade

The system can be extended with the features of the MAGIC DABMUX plus multiplexer via software upgrade:

  • Output: 4 x EDI (ETI) Simulcast
  • Automatic Encoders and Multiplexer Redundancy
  • 4 x integrated NPAD inserter
  • 4 x EDI input incl. automatic service extraction
  • Support of Service Linking, Dynamic Linkage Set Activation
  • Integrated PAD inserter: SLS,DL(+)
  • Connection of 25 encoders (with redundancy)


Emergency Warning Break-In Upgrade

The EWB upgrade, besides setting the correct announcement flag, enables the simultaneous replacement of all audio content by an emergency announcement. This ensures that the announcement is audible even with older receivers. One additional MAGIC AE1 DAB+ Go or MAGIC AE4 Audio Encoder is required as emergency audio source.


Cable Upgrade

An additional operating mode for cable networks is offered with the Cable Upgrade. The EDI input signal is analysed. The EDI output signal can be reformatted, the protection level and the service label can be changed.


Redundant Power Supply

An optional redundant 230V power supply is available for the system.

Switch Redundancy Upgrade

The upgrade extends a redundant multiplexer system with seamless EDI redundancy switching for 2-way distribution of the EDI signal.

The function requires the MAGIC DABMUX plus Software Upgrade.


Redundancy+ Upgrade

The upgrade enables a 1-way EDI distribution. The two redundant multiplexer systems monitor each other so that only one of the two systems sends the EDI signal at a time. Both the source and destination IP address can be configured identically for both multiplexers.

The function requires the MAGIC DABMUX plus Software Upgrade as well as the Switch Redundancy Upgrade.


DAB System Manager Upgrade

The DAB System Manager upgrade allows the management and monitoring of all AVT DAB Headend System components via an HTML5-compatible browser. Currently the systems MAGIC DABMUX Go and MAGIC DABMUX plus are supported. The integration of the MAGIC AE1 DAB+ Go, the MAGIC AE4 DAB/DAB+ Encoder as well as the MAGIC EEC/SDC family will take place in a later release.

Key features are:

  • Common system monitoring
  • Redundancy view with manual main/backup path switching
  • Common log file of all system components using an SQL database
  • Email alert
  • Unlimited number of users with assignable rights
  • Central firmware update of all components


Monitoring Decoder Upgrade

The decoder upgrade allows the monitoring of any programme of the ensemble directly in the user interface.

PAD decoding and service information are supported by the monitoring decoder.
