What is a Telephone hybrid?
Telephone hybrids 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 canceling 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 connectors
for audio input and output from a broadcast mixer, or other professional audio source.
A large proportion of D&R hybrids are used in radio and television broadcasting applications
allowing external callers to be connected to the studio mixing console. Most of the other units
are supplied to communication operations allowing extremely effective conversion between 4-
wire audio circuits and standard telephone lines.
