The Sonifex HY-03 is a free-standing automatic analogue TBU. Telephone hybrids, or telephone balance units (TBUs) provide the interface between professional audio equipment and the public telephone network.

The Sonifex HY-03 is a free-standing automatic analogue TBU. Telephone hybrids, or telephone balance units (TBUs) provide the interface between professional audio equipment and the public telephone network. They provide protection for your equipment and the public telephone lines, allowing for varying line signals and line conditions. Automatically cancelling out the unwanted signal they also facilitate two-way communication down a single telephone line.
The analogue Sonifex 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.
The HY-03 retains many of the features of the HY-02 and adds some additional ones.

Some of the features of the HY-03 include :

  •  Fully automatic - adapts to varying line conditions and has automatic signal limiting.
  •  Local and remote line hold switching - calls can be remotely switched through a mixing console.
  •  Momentary or permanent latching remotes can be enabled.
  •  Balanced mic/line input - 10k ohm balanced input selectable for 0dBu clean feed line, or microphone level with adjustable gain.
  •  Balanced output - 0dBu low impedance balanced output, with output gain adjustment.
  •  Mixed output - the output can be a mix of the caller and mic/line input signals for recording both sides of the telephone conversation.
  •  Integrated ring detector - automatic call answering after a pre-determined number of rings.
  •  Fitted with K-break disconnect detection as standard with an option for dial-tone disconnect using the optional HY-03DTD board. The HY-03DTD board can be configured to disconnect on recognizing the dial tone used in a specific country.
  •  Line limiter, bandpass filter and output noise gate with preset threshold providing low distortion crystal clear audio.
  •  28dB typical line balance rejection.
  •  Built in power supply with switchable 115V, or 230V, mains input.
  •  BABT approval compliant with European PTT specifications.
