The digital DHY-03 telephone hybrid isone ofthe best performing digital hybrids in the world, with simply stunning line balance rejection figures.

  • Fully automatic - adapts to varying line conditions and has automatic signal limiting.
  • Fully adaptive echo cancellation to 127msec - default is 24msec.
  • 76dB 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.
  • Local and remote line hold switching - calls can be remotely switched through a mixing console.
  • Line hold/release button to control line hold circuit, illuminates to indicate the status of the line and flashes to show ring status.
  • DTMF tone recognition allowing a opto-isolated GPI output to be made on receipt of selected DTMF tones, e.g. for starting a studio automation recorder automatically to record a remote telephone interview.
  • International operation with built-in configurable settings for each country. Country selection allows the unit to provide line impedance and a simulation circuit to match the country.
  • RS232 serial port for remote control of the TBU, DTMF tone dialling and firmware upgrades to add new country settings.
  • Remote port distributes the remote line connect switch and tally output, a momentary/latch selector and the DTMF detect output.
  • The remote line connect switch can be either momentary or latching in its action.
  • Balanced mic/line input - 10k balanced input selectable for 0dBu clean feed line, or microphone level with adjustable gain.
  • Balanced output - 0dBu low impedance balanced output, with output gain settings.
  • Record output - the conferencing output can be set via a jumper to give a mix of the caller and mic/line input signals for recording both sides of the telephone conversation.
  • Line limiter, bandpass filter and output noise gate with preset threshold providing low distortion audio.
  • Built in universal power supply between 90V AC and 250V AC, 47-63Hz, IEC mains input.
  • ETSI approval compliant with European PTT specifications.
