AVT Audio Visual Technologies GmbH develops innovative telephone hybrids and codecs for broadcasters and service providers around the world.
AVT provides the following systems.
Telephone Hybrids
Audio Codecs
DAB/DAB+
Telephone Hybrids
Telephone Hybrids, also known as Talkshow Systems, convert incoming phone calls into audio signals which are then suitable for a studio environment. Three primary line interfaces exist: POTS (analogue telephone lines), ISDN and Ethernet interfaces using Voice over IP technology.
All AVT MAGIC telephone hybrid systems are now compatible with Microsoft Teams!
MAGIC TH1Go Telephone Hybrid
Single-hybrid solution with analog audio interfaces. Two system configurations are available. The first configuration is via the LAN interface as a 1-channel VoIP hybrid. The second is via the analog interface as a 1-channel POTS hybrid (analog a/b telephone lines).
Digital Echocanceller, Automatic Gain Control (AGC) and Expander
Control via analogue telephone, web browser or Windows PC Software
Pretalk via analogue telephone or second audio interface
Voice disguise for caller identity protection
Recording of HOLD signal or external signal as HOLD signal
MAGIC TH2plus Telephone Hybrid
This dual hybrid solution comes with three operating modes in a single system: two analog a/b interfaces, one ISDN So, and one LAN interface. Thanks to these options, the system can be used in analog, ISDN and VoIP mode. An external GSM adapter allows for an extension to a GSM telephone hybrid. It provides many of the same features as the TH1Go but for each of the two channels.
Digital Echo Canceller, Automatic Gain Control (AGC) and Expander for each channel
PC software with screening function
HOLD signal: external, recorded or ON AIR signal
Ember+ & DHD SetLogic
Voice disguise for caller identity protection
Call forwarding & last calls list
MAGIC THipPro Lite Telephone Hybrid
With a reduced range of functions, THipPro Lite is available with 4 or 8 caller lines and has two LAN interfaces used for control and VoIP calls (option). Alternatively, integrate POTS modules to provide 4 or 8 POTS interfaces for connection to analogue telephone lines. It has four digital audio lines (two AES/EBU interfaces) and two analogue audio inputs & outputs.
Digital echo canceller, AGC and expander for each caller line
PC software with screening function
HOLD signal: external, recorder or ON AIR
Support of Ember+ protocol and DHD SetLogic IDs
Dante/Ravenna/AES67 upgrade for additional audio lines
MAGIC THipPro Pure Lite
For those who no longer require conventional audio interfaces, the MAGIC THipPro Pure Lite variant is available. Use the optional AES67 software upgrade or the Dante or Ravenna module for audio connection.
MAGIC THipPro Telephone Hybrid
This flexible and functional 8 line system is available for POTS, ISDN, or VoIP while the 16 line system is available for ISDN or VoIP. In “Mixed Mode,” the system can be operated with POTS or ISDN lines and simultaneously with VoIP lines.
Digital echo canceller, AGC & expander for every caller line
Conference function with N-1 generation
20 MAGIC THipPro LAN & Screener software workplaces
PRETALK mode with multiple screening functions
Ember+ support & DHD SetLogic IDs
Dante/AES67 upgrade to add additional audio lines
MAGIC THipPro Pure
The MAGIC THipPro Pure variant does without conventional audio interfaces, relying entirely on AoIP standards for its audio connections. Connect to the audio infrastructure via Ravenna, Dante or AES67 via RJ45.
MAGIC Server
This scalable, software-based telephone hybrid & audio codec server is modular and can be configured according to specific requirements and applications.
Software telephone hybrid & audio codec
Windows application
Basic: 1 – 8 VoIP lines
Professional: 8 to 96 VoIP lines
Up to 24 studios
Integration of MAGIC Collaboration Services, OPUS & PCM Audio Codecs
MAGIC THipPro VoIP Intercom System
The new MAGIC THipPro VoIP is a DSP-based gateway with 8 or 16 VoIP lines. Available in two versions*, MAGIC THipPro 8 VoIP Intercom (8 lines) and MAGIC THipPro 16 VoIP Intercom (16 lines), the 1U device includes 8 digital audio lines (4 AES/EBU interfaces) as well as two analogue audio inputs and outputs. This solution also features up to 10 systems with 160 voice channels.
*The 8-line system can be easily extended to 16 lines via a hardware upgrade.
MAGIC THipPro VoIP VMS
The MAGIC THipPro is an answering machine that connects to VoIP-capable PBXs or VoIP main lines. This voicemail system is expandable up to 32 recording channels in one surface. These recordings are stored on the server as WAV files.
Two versions of this system are available: MAGIC THipPro 8 VoIP VMS (8 caller lines) and MAGIC THipPro 16 VoIP VMS (16 caller lines). The 8-line system can be easily extended to 16 lines via a hardware upgrade.
Audio Codecs
MAGIC ACX Dante WAN Bridge
The MAGIC ACX Dante WAN Bridge is a multi-channel PCM system that enables transmission of up to 32 uncompressed audio signals via wide area networks (WAN). This 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. Up to 10 systems can be managed 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).
