1 What Is A Telephone Hybrid?
Telephone hybrids, or telephone balance units (TBUs) provide the interface
between professional audio equipment and the telephone networks. They
provide protection for your equipment and the telephone lines, allowing for
varying line signals and line conditions. Automatically cancelling out the
unwanted signal they also facilitate two-way communication down a single
telephone line.
A typical telephone hybrid has a telephone line connection, a handset
connection and separate terminals for audio input and output from a
broadcast mixer, or other professional audio source. This GSM unit has no
telephone line or handset connection, using an internal GSM receiver/
transmitter to receive and make calls.
A large proportion of Sonifex hybrids are used in radio and television
broadcasting applications for allowing external callers to be connected to
the studio mixing console. Most of the other units are supplied to
communication operations for allowing extremely effective conversion
between 4-wire audio circuits and standard telephone lines.
DHY-04V Single Automatic GSM Hybrid, AES/EBU &
Analogue I/O With Ethernet
The DHY-04V VoLTE Hybrid is used on a cellular (mobile) phone network,
and provides HD Voice quality calling over 4G, as legacy 3G and 2G mobile
services in many countries are now being switched off. The DHY-04V can
accept a SIM card in the rear panel slot and by connecting a suitable GSM
antenna, it can receive and make high quality broadcast calls over the
cellular network, converting the 4G call to the 4 wire audio signal to and
from a connected mixing console. The module used in the DHY-04V can
take and make calls on any 4G GSM network, and can fallback to 3G and 2G
if required.
It is ideal for studios in remote locations, for OB vans and trucks on the
move, and in emergency situations where a telephone landline can’t be
guaranteed, the DHY-04V offers outstanding performance.
The DHY-04V has all features of the DHY-04 together with some additional
front panel indicators. There are two LEDs, one for SIM enabled and one for
GSM Network availability. Additionally there is a push button which allows
the mobile signal level to be displayed on the meter LEDs.
