| Telephone hybrids (or telephone balance units)
provide the interface between professional audio equipment and the public
telephone network. They provide protection for your equipment and the
public 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.
Each 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. 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. |

The HY-03 is a high quality analogue
telephone hybrid, which is suitable for most general telephony
applications and is often used in radio and TV stations, bingo
halls and dealing floors. The analogue HY-03 telephone hybrid
is the replacement for the HY-02, which for many years has set
the standard as an excellent value, high quality telephone hybrid.

The DHY-02 uses digital signal
processing to achieve superb results and is the best "value for
money" hybrid that you'll find when comparing technical performance.
It is also fully automatic with echo cancellation to 28msec and
includes bar graph metering of send and receive signals. The DHY-02
series perform exactly the same function as the analogue units,
but have some additional benefits.
