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.
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.
But the advantages do not end here
The DH400 is driven by a microcomputer, which supports several work modes that other systems do not possess. For example, it can handle four telephones sets for a radio call center. The local phone operator is able to write, on the PC screen, the name of the caller and any other valuable data, which is immediately transferred to the entire radio PC network, using our free DH400 software. With a simple touch of the Flash button at the telephone set, the telephone operator places on HOLD the phone call without disturbing the console operator. Then, the local talent can switch On-Air the caller, knowing beforehand all the basic information about the caller.
It is possible to change the lines status (Off, Hold, On-Air, Conference, etc) from anywhere in the LAN where DH400 software is installed, using a mouse, the keyboard or a touch screen PC. So simple, and all automatic. Even the console operator, if desired, can refrain from intervening.
DH400 is able to work full automatic, 24 hours a day, attending phone lines, with personalized welcome message, and automatically recording 4 lines simultaneously. The recording is of high quality, unlike the PC telephone answering machines.
During the night, a single DJ operator can handle the radio. DH400 attends four lines with the welcome message and then places it on HOLD status, with transference to the radio DJ. Pushing the NEXT button, the oldest caller on Hold will go On-Air. In all cases DH400 can be operated from its front panel or through PC software.
Excellent audio quality; The absence of local voice return due echo cancellation algorithms, allows for excellent audio quality. And even better, the internal VQR (Voice Quality Restoration) processing allows for high On-Air audio quality, that the audience usually do not distinguish from an interview in Studies
