Sonifex HY03US Automatic Analogue TBU, Free Standing

The Sonifex HY03US is a freestanding automatic analog telephone hybrid that replaces the long - established HY - 02. It offers great value and high - quality performance, retaining features from the HY - 02 and adding new ones. Key features include full automation to adapt to different line conditions and automatic signal limiting. You can switch local and remote line holds, with options for momentary or permanent latching remotes. It has a balanced mic/line input with selectable 10k ohm for a 0dBu clean feed line or microphone level with adjustable gain, and a balanced output with gain adjustment. The mixed output allows you to record both sides of a phone conversation. There's an integrated ring detector for automatic call answering after a set number of rings. It comes standard with K - break disconnect detection and has an option for dial - tone disconnect using the optional HY - 03DTD board. It also features a line limiter, bandpass filter, and output noise gate for clear audio, 28dB typical line balance rejection, and a built - in power supply with switchable 115V or 230V mains input. Technical specs: Audio input impedance varies by mode (10kOHMS balanced 0dB in line mode, 2kOHMS balanced in microphone mode). Clean feed limiting input is +4dBu, and microphone level can be adjusted from 74dB to 40dB. Bandwidth to the telephone line is 250Hz - 4kHz. Output impedance is 50OHMS balanced floating 0dBu, and output level can be adjusted from +8dB to - 14dB. Rejection ratio is 45dB on 1kHz tone, typically 28dB on complex waveforms. Ring detector sensitivity ranges from 1 to 6 rings. Power options are 230V 50Hz or 115V 60Hz, with 6W power consumption. Connections include XLR 3 - pin female for mic/line input, XLR 3 - pin male for line output, RJ11 6/4 sockets for telephone line and handset, a 9 - way D - type socket for remotes, and an IEC mains (CEE22) for power.

Using the Sonifex HY03US is straightforward. First, connect the power supply. You can choose between 115V or 230V based on your local power grid. Then, connect your microphone or line input to the XLR 3 - pin female socket. Select the mode using the push - button. Connect the telephone line and handset to the RJ11 6/4 sockets. The HY03US will automatically adapt to different line conditions. You can set the number of rings for automatic call answering with the ring detector. When using the remote functions, connect your device to the 9 - way D - type socket. You can switch calls remotely through a mixing console. For the output, adjust the gain to get the desired sound level. Keep the unit in a dry and cool place. Avoid exposing it to extreme temperatures or humidity. Regularly check the connections to make sure they are secure. If you need to use the optional HY - 03DTD board for dial - tone disconnect, configure it according to the dial - tone of your country.
