Telos Hx Digital Hybrids

Calls come into your studio from anywhere, any quality, any way they can. Now those chaotic POTS lines can be harnessed, tamed and controlled in the blink of an eye. Telos pioneered digital adaptive telephone hybrids in the 1980s and works tirelessly to meet today’s new demands.

The new era in digital hybrids starts here.

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. So has anything changed in 25 years? Yes. POTS got freakishly wilder. The Telos hybrid got exponentially smarter.

This is the Telos Hx – 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 the single-hybrid Hx1 and dual-hybrid Hx2, you’ll find our 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 brought to submission. The power supply is now internal. New features like 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 and Hx2. It offers more features but costs less. It sounds better and works harder but is easy to configure and simple to install. Make wiggy POTS signals work in your studio for broadcast, podcast or whatever. The Hx1 and Hx2 will make it happen.
