SONIFEX DIGITAL TELEPHONE BALANCE UNITS

DHY-03

This digital version of the industry standard HY-03 uses Digital Signal Processing to give much enhanced performance over the more established types, for use where the best quality telephone interfacing is required, typically in broadcast phone-in and news/sport applications.

The send and receive paths are transformer balanced and isolated, and connect to the other equipment via XLR style connectors, with input and output gain controls for ±6dB adjustment. Independent LED bargraph metering of send and receive levels aids set-up, the illuminating “connect” or “divert” switch has remote control facilities, and K-break, reverse polarity and dial tone disconnect functions are provided for the phone line, which connects via and RJ11 socket for the line and for the telephone handset.

Analogue limiting, controlled by the DSP, prevents overload, whilst the unit automatically reacts to changing line conditions and programme content. The use of DSP increases the unwanted sideband rejection to 72dB(measured using tone, ref. 0dBu peak output), and offers full adaptive echo cancellation to 127msec default is set to 24msec.

Other features on this unit are built-in conferencing for 2 hybrids (using the optional DHY-03CONF conferencing cable), so that a single telco channel on a mixing desk can receive 2 calls, an integrated ring detector that can automatically answer calls after 2, 4 or 6 rings,DTMF tone detection to assist in studio automation and automatic “ducking” facility to allow the user to talk-over a caller by reducing the caller signal gain if the user level exceeds a threshold, allow the DHY-03 to take on many roles.

A Eurocard version of the DHY-03 is available, with a DIN 41612 connector, which requires an external BABT approved power supply. This offers similar electronic features as the cased units, but, obviously, is not fitted with XLR connectors and controls, is without mic input and conference function and levels are shown on dual LEDs.

ETSI approval compliant with European PTT specifications (EC version is BABT approved for number S/3619/3/L/501782 only).
