The three Telos ONE models present superb digital telephone hybrid performance for broadcast, teleconferencing, and communications applications. Proven Telos processing technologies perform all hybrid functions, gain control, and filtering completely in the digital domain. The use of intelligent software, rather than complex hardware, makes the Telos ONE very affordable while ensuring consistently superior performance regardless of telephone line characteristics. (See the "Q&A-Analog Systems" link in our Tech Talk section for more on this.)

Fast, precise automatic digital nulling allows smooth, natural, simultaneous conversation without the usual speakerphone up-cutting effect, voice distortion, and level matching problems often experienced with other hybrid-type interface devices.

The Telos ONE comes in three versions: A single hybrid, available in either a compact modem case (Model 120) or standard rack mount chassis (Model 125), and the ONE+ONE, a dual hybrid with a built-in mix-minus matrix. With the exception of the power supply, the rack mounting and modem case versions of the Telos ONE are electronically identical.

For multiple hybrid installations, the Telos ONE plus ONE contains two hybrids with a mix-minus matrix in a single rack unit enclosure. The matrix cross-couples the outputs of the two hybrids, so you need to send the ONE plus ONE only one mix-minus to feed both hybrids.
