Sonifex HY03US Automatic Analogue TBU, Free Standing

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. The HY-03 retains many of the features of the HY-02 and adds some additional ones.

Key Features

• 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
