Sonifex DHY-02SR DIGITAL AUTOMATIC TELEPHONE BALANCE UNIT Single rack mounted

The telephone hybrid is a two wire to four wire converter which provides the interface between a caller on the telephone line and the input to the mixing desk. Built to a very high specification, it is simple to install and automatically adapts to line conditions and programme content. Analogue signal limiting, controlled from the DSP, is used in the send and receive paths to ensure that signal break-up and severe overload problems do not occur.

The unit has independent LED bar graph metering of send and receive levels with input and output gain controls provided at the front panel. Both the input and the output are transformer balanced providing complete isolation.

The illuminating line connect control has a remote facility and the equipment is fitted with K-break and dial tone disconnect as standard. Audio connectors are the standard XLR-3 type.

By using a high power DSP and a high quality 16 bit dual codec, the HY02 Digital gives some of the best audio figures available - it provides full adaptive echo cancellation to 28msec and gives unwanted sideband rejection figures of 69dBu on tone, reference peak output of +8dB. The HY02 Digital has been designed to achieve the best possible audio performance from a telephone line. The unit ensures that the dynamic range is as large and the distortion and noise are as small as possible.

The following product description is necessary for BABT approval and provides information on the connection and operating conditions of the units.
