Digital Audio Broadcasting • DAB/DAB+ • Solutions by AVT

The digital broadcast technology DAB (Digital Audio Broadcasting) broadband system allows users to transmit several programmes from one or more programme provider in one Ensemble.

AVT manufactures a variety of DAB systems, offering complete solutions for DAB headends.

Digital Audio Broadcasting, the successor of analogue radio, has significant advantages including: efficient distribution options, various data services such as SlideShow for album covers, SPI(EPG), TPEG for extended traffic information etc., and noise-free audio programs.

Create 15-20 audio programmes by multiplexing a single frequency within an ensemble. Install hardware-based DAB/DAB+ Audio Encoders separately and directly from the program providers. Achieve the best possible audio quality by avoiding multiple coding in the input. Program providers who are also ensemble providers and broadcast several programs can set up software-based Audio Encoders directly on the Ensemble Multiplexer or use single or multi-channel hardware Audio Encoders.

AVT_MAGIC DABMUXplus_EnsembleMultiplexer_TEVIOS

The central system of a DAB headend is the Ensemble Multiplexer. AVT offers four different systems ranging from small-scale DAB multiplexers to professional DAB multiplexers on DSP base or based on the Fraunhofer ContentServer.

Monitor an ensemble multiplex with the ETI/EDI Monitoring Decoder. For more in-depth analysis of the DAB signal, a wired ETI/EDI analyser with integrated ensemble recorder and player is available.

And finally, the DSP-based, highly available and maintenance-free Tunnel Break-In System with integrated modulator & remodulator offers a voice break-in for up to two independent ensembles.

High-Quality Audio Transmissions with Audio Codecs by AVT

Audio Codecs are required for high-quality audio transmissions over various networks including IP, ISDN, 2-Mbit/s (E1) and X.21. Over IP and ISDN, use both Leased Line and temporary dial-up connections with AVT’s audio codecs.

The various applications for Audio Codecs include: reporting, studio programme contribution & distribution, and Studio-Transmitter-Links.

AVT_MAGIC Dante WAN Bridge_audiotransmission_TEVIOS

One of the popular Audio Codecs by AVT is the MAGIC ACX Dante WAN Bridge. This multi-channel PCM system enables transmission of up to 32 uncompressed audio signals via wide area networks (WAN). In other words, it enables Dante Network connections over large distances. The coding is done via PCM16/PCM24/PCM32. The integrated 32-channel Dante interface provides audio connection for the audio inputs/outputs. It also features redundant GbE interfaces and supports AES67. Manage up to 10 systems from five workplaces thanks to its user-friendly operating software.

Limited maximum latency of Dante in wide area networks, high jitter and possible time differences can make reliable transmission difficult. The MAGIC ACX Dante WAN Bridge solves these issues by offering a jitter buffer that includes an automatic mode and intelligent sample rate adaption (SRA).

AVT Integrates Ravenna module

Just as most AVT systems have the software-based AES67 integration and the Dante module, now the RAVENNA module is available on select AVT systems!


Offering the Ravenna solution provides users the best possible integration in their studio environments. Integration into large AoIP networks is significantly simplified, thanks to the new module’s support of the NMOS specifications for Discovery & Registration and Device Connection Management.

Currently, the MAGIC RAVENNA module is available on the VoIP telephone ­hybrid­ system MAGIC THipPro. Once the module is equipped, 32 x 32 additional audio channels are available via IP, which can then be distributed to up to 32 network streams. Plus, continue to utilize the analogue and digital audio interfaces of the MAGIC THipPro.

Soon the Quad DAB+ Encoder MAGIC AE4 and the DAB Ensemble Multiplexer MAGIC DABMUX plus will also include the MAGIC RAVENNA module.

In order to guarantee high compatibility with other systems, the AES67 and SMPTE ST 2110-30/31 standards are also supported.

Finally, integrated stream redundancy for all ST 2022-7 classes effectively prevents interruptions in the audio signal caused by network problems.

Contact us for more information about the Ravenna module now available on AVT systems.
