AVT MAGIC TH2plus Telephone Hybrid
Telephone Hybrids convert an incoming call into an Audio signal for
the studio environment. The line echoes on analogue telephone
interfaces which result from the 2-wire technology used are disturbing
and must be eliminated by line echo cancellers.
To achieve the best results for the elimination of the echoes,
digital procedures with signal processors are used in POTS Telephone
Hybrids. However, in ISDN connections, no line echoes will occur due to
the use of the 4-wire technology. If analogue telephone calls are
received by ISDN Telephone Hybrids, echoes can also be detected due to
the conversion from 2- wire to 4-wire technology in the analogue
telephone unit. For clear communication digital line echo cancellers are

The MAGIC TH2plus Telephone Hybrid provides two POTS,an ISDN BRI (S0)
and a LAN line interface, which can be used for VoIP. The system has
analogue and digital Audio interfaces (configurable) and can be operated
as double hybrid in all three modes (POTS, ISDN and IP).
For each caller line a separate Echo Canceller is available. The Echo Cancelling window is about 100 msec.
The operation and configuration can be done via the
front keypad and the graphical display. Alternatively, an operation via
the GPIO contacts and the Windows PC Software, which is included in
delivery, is also possible.
software allows you to configure and control the system with a PC via
LAN. Both caller lines are clearly displayed and if desired a manual
level adjustment is possible. Screening information about the callers
can be stored in a database. The stored caller information is
immediately available when the calling number is transmitted. With the
help of additional MAGIC TH2plus Software licences you can install up to two further operator or Screener workplaces.
