DH 400 Digital Phone Hybrid with DSP echo canceller DH400 is the only Hybrid at market that allows you to configure all settings from any point at the LAN network And, of course, the only one that restores the original voice quality...   The DH 400 system is the culmination of 40 years of experience in manufacturing at Solidyne, broadcasting phone hybrids, PBX telephone exchanges and telephone sets. No other company of this market has the same triple experience. So none of them produce such an advanced system that allows configuring in seconds from anywhere on the radio, through the LAN, the way that the telephone lines are used for recording of calls, for on-air interviews or tele-voting. Throughout the day the radio station can reschedule their lines and their hybrids. You only need a simple "click". The DH400 handle 4 telephone lines , one of them could be a cellular phone. The audio signal is digitized and processed within 4 units DSP (Digital Signal Processor). Rejection of the hybrid is automatically adjusted in two seconds and reaches values of 45 to 60 dB. We get such high value, using a technology called digital echo cancellation . This local voice high rejection allows the user to hear at the caller using loudspeakers in large radio studios, auditoriums or television sets.   DH400: the solution for broadcastings with audience call centers or telephone based radio programs     During the programs with great audience participation, the DH400 transferred audience calls to call center.
