Description: Working dual units. Sign of use but good condition. The digital DHY-03 telephone hybrid is probably the best performing digital hybrid in the world, with simply stunning line balance rejection figures. For the best sounding audio calls you’re likely to hear, you should specify the DHY-03. The DHY-03 has the following features :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.
