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!

AVT_MagicTh1ipgo_TelephoneHybrid_TEVIOS

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
AVT_MagicTh2plus_TelephoneHybrid_TEVIOS

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 Pure Lite with Dante Module

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 Pure

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.

AVT_MagicThippro_Intercom_TEVIOS

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).
