TH2

The TH2 Digital Hybrid is part of the LecNetTM family of audio products. The TH2 works with any standard two wire telephone system, to provide a convenient and inexpensive means of using any sound system for teleconferencing. This product is microprocessor controlled, with a powerful Digital Signal Processor (DSP) actively adjusting the line balance to achieve maximum transmit and receive signal separation. In addition, echo suppression based on Lectrosonics patented Adaptive Proportional Gain algorithm (U. S. Patents No. 5402500 and 5414776) minimizes acoustic echo while maintaining virtually full-duplex operation. The TH2 can be setup manually or with an IBM compatible PC in the PC Remote mode. Manual setup is accomplished by adjusting three trimmer potentiometers and a set of dip switches. Four push-buttons and a wired remote control port provide a convenient way to control the operation of the TH2 locally or remotely.
