NEW AVT Scalable Telephone Hybrid & Audio Codec Software Solution

The new MAGIC Server by AVT expands their telephone hybrid portfolio with a scalable, software-based telephone hybrid & audio codec server.

AVT_MAGICServer_ software-solution_Dashboard_TEVIOS

With MAGIC Server, MAGIC telephone hybrids and audio codecs are available as a centralized, scalable software solution. As AVT explains: “The integration supports all functionalities of the hardware system and integrates MAGIC Collaboration Services for MS Teams and WebRTC connectivity which were introduced at IBC 2022.”

In addition to the MAGIC Server Software, just a regular server or VM is required.

Two versions of MAGIC Server will be available:

MAGIC Server Basic

  • 1-8 VoIP telephone channels
  • 1-8 web operating clients
  • 1-2 studios

Integrate two stereo Audio Codecs and Collaboration Services such as WebRTC or MS Teams for high-quality audio and video transmissions. This makes two lines OPUS-, PCM-, WebRTC– and MS Teams-capable.

MAGIC Server Professional

  • 8 to 96 VoIP telephone hybrid channels
  • 24 studios with 48 application-specific web control clients
  • 48 recording booths (News Desks) for telephone interviews
  • 6 Intercom groups for communication with correspondents or remote stations

Use up to 24 channels for high-quality stereo audio transmissions (OPUS, PCM), and add 48 audio or 24 audio/video WebRTC / MS Teams collaboration services.

In other words, MAGIC Server Professional makes it easy to expand the system whenever necessary.

Witness this scalable telephone hybrid & audio codec software solution firsthand at IBC 2023, stand 8.F76.

AVT Announces MAGIC Collaboration Server with Video

AVT releases its MAGIC Collaboration Server with Video! With the MAGIC Collaboration Server, the MAGIC telephone hybrids enable connection to Microsoft Teams collaboration software. In other words, an integrated video signal joins the list of current functions.

The MAGIC Collaboration Server is available in a modular approach. Use it for audio only or with the addition of a video signal. Thanks to the Satin Codec used in MS Teams, the quality is independent from the network infrastructure.


At this time, Microsoft Teams calls are possible in the same, simple workflow as normal calls. The video signal is displayed directly in the user interface and can also be output via NDI.

Support for Web-RTC will be added later this year to make the MAGIC Collaboration Server even more versatile.

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.

Contact us to learn more about the DAB/DAB+ solutions by AVT.

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).
