Telos HX1HX1rear

The Telos Hx1 represents the highest state-of-the-art in hybrid performance, with Telos processing technologies that take the POTS hybrid to a new level of consistently superior performance, regardless of telephone line characteristics.

Inside the single-hybrid Hx1, you'll find advanced hybrid technology with new features that significantly sweeten and control caller audio. It comes standard with Auto-Answer, caller disconnect detection, sophisticated new audio-leveling and anti-feedback routines for enhanced open-speaker applications, call screening and line-hold features, front-panel send and receive audio metering, plus much more.

Telos Hx1 Features:

* Advanced hybrid algorithms

* New symmetrical wide-range AGC and noise gate by Omnia, with adjustable gain settings

* Studio adaption and pitch shifter help prevent feedback in situations where open speakers are required

* Adjustable caller override improves performance and allows you to individualize the degree to which the announcer ducks the caller audio

* Digital Dynamic EQ and adjustable smart leveler keeps audio spectrally consistent from call to call

* New EQ High and EQ Low display meters

* Separate Send level and Receive level meters

* Status Symbols make life easier for producers and talent with their animated high-contrast icon display of line status

* Place caller on-hold via front panel button

* Auto-Answer with selectable ring count

* Worldwide disconnect signal detection. (loop drop, dial tone, or re-order tone)

* Input/output via analog XLR

* Input switchable between MIC or LINE levels

* All Telos products include a 5 year warranty
