HY-03

The HY-03 is an electronic telephone hybrid unit (“4 wire to 2 wire converter”) which automatically compensates for variable line resistance and reactance whilst the line is connected. All units in the range are fully approved by BABT with “green dot” approval S/3619/23/L/501792 and are compliant with European PTT specifications. The analogue HY-03 telephone hybrid is the replacement for the HY-02, which for many years has set the standard as an excellent value, high quality telephone hybrid. As well as other extra features the HY-03 also includes a ringing detector as standard.

The telephone line is isolated from the equipment by a disconnection barrier and an approved line transformer, and may be switched between a local handset and the equipment by means of an illuminated “LINE CONNECT” switch which also serves as an “ON” and “RING” indicator. When switched to “LINE CONNECT” the equipment holds the telephone call. This switch function can be operated remotely.

The HY-03 may be used with 0dBu clean feed input signals, or alternatively, direct connection of a microphone input, which is adjustable between 74db to 40dB on a rear preset adjustment, may be used. The balanced clean feed input has a bandpass filter, and is limited to give peak levels of +4dBu at the telephone line. The output circuitry processes the telephone signal to give 0dBu output from the equipment, and then balances or rejects the clean feed signal automatically under varying line conditions. The rejection is constantly reviewed during the presence of clean feed signals to optimise the equipment for prevailing line conditions. The telephone signal is processed through a bandpass filter and noise gate which downward expands during no signal conditions to eliminate line cross talk and associated noise.

The output of the HY-03 is an XLR-3 pin male connector with a nominal level of 0dBu balanced low impedance. The level is adjustable between +8db to -14dB on a rear preset adjustment. The output can also be set as a mix of the caller and mic/line input signals to allow a recording of both sides of a telephone conversation.

The included ringing detector allows the HY-03 to auto answer incoming calls. It can be pre-set to answer incoming calls on either the first ringing cadence through to the sixth ringing cadence. The “LINE CONNECT” switch is illuminated each time a ringing cadence is present, and an opto coupler presents an active open collector output suitable for driving a white light indicator on the remote connection. The unit is fitted with K-break disconnection (UK use) as standard but an optional HY-03DTD board is available to equip the HY-03 for disconnection upon detecting dial-tone.

The HY-03 unit is also available as a single 1U rack-mounted version or a twin 1U rack-mounted version.
