Telos Hx1 Digital Telephone Hybrid
A quarter-century ago, Telos introduced the world’s first digital adaptive telephone hybrid. Broadcasters celebrated – at last, POTS signals could be made clear, clean and reliable to go to air. In the last 25 years, POTS got freakishly wilder; however, the Telos hybrid got exponentially smarter. This Telos Hx is the thinking hybrid. All of Telos' exceptional processing and an array of new technologies make this POTS hybrid a revolution in consistently superior performance.
Inside this single hybrid unit is advanced hybrid technology with new features to sweeten and control caller audio better than ever before. Omnia processing intuitively manages levels and EQ. Extra DSP power is added so even unruly mobile phone audio is normalized. Built-in Auto-Answer, caller disconnect detection, ingenious audio-leveling and anti-feedback routines for enhanced open-speaker applications, call screening and line-hold features, and front-panel send and receive audio metering are standard on the Hx.
Telos has reinvented the digital hybrid with the Hx1. It offers more features, sounds better, and works harder but is easy to configure and simple to install. Make wiggy POTS signals work in your studio for broadcast or podcast.
