Clearone XAPTH2 Phone Teleconference System



The Clear One XAP TH2 Telephone Interface is a single-line digital hybrid which uses digital signal processing (DSP) to separate the transmit and receive audio, eliminating distortion, weak signals, and feedback. It continually filters low and high frequency noise to provide pure sound. The XAP TH2 is designed to function as a stand-alone telephone hybrid or as an accessory to the XAP 800 (echo cancelling, audio processing, microphone mixing matrix), enabling you to add remote callers to your audio conferences.
