About Sonifex DHY-03T
The Sonifex DHY-03T Twin is a high quality digital 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 digital DHY-03T telephone hybrid is the replacement for the DHY-02, which for many years has set the standard as an excellent value, high quality telephone hybrid. The DHY-03T can be used for any application where a clean telephone signal is required and the line is not subject to excessive delay.
Sonifex DHY-03T Features

- 75dB typical line balance rejection offering superb performance and crystal clear audio
- Front panel input and output gain controls
- Front panel LED metering of receive and send signals
- Built-in conferencing for 2 hybrids, so that a single telco channel on a mixing desk can receive 2 calls
- Integrated ring detector - automatic call answering after a pre-determined number of rings
- Automatic call disconnection. Fitted with K-break, line polarity reversal and dial tone disconnect detection, defined by the country selection
- Automatic ducking facility allows the talent to 'shout-down' or talk over, a caller by reducing the gain of the caller's signal if it goes above a certain level
