Telos ONE Digital Hybrid Telephone Interface, Modem Case Version (USED)
Our Notes: This telephone interface is missing its power supply (9V DC, 500ma).
This compact, modem-case device presents 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.
Fast, precise automatic digital nulling allows smooth, natural, simultaneous conversation without speakerphone up-cutting effect, voice distortion, or level-matching problems.
