Telephone Hybrids - HY-03 - Series (Analogue)

    • 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.

    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.
