Digital Interface Recording Board
To meet the high-performance requirements in the recording monitoring field, DONJIN develops the high-impedance digital recording board. After users make a secondary development based on the API, the recording function can be performed. At present, the products cover almost all recording market applications and signaling formats. Meanwhile, the solution of telephone recording system is simple, secure, and also reliable.
Download l The board adopts the wire tapping recording in a parallel work mode;
l One board can process a maximum of 30/120 voice channels, and the full duplex voice can be overlaid automatically;
l Provide the synchronous voice playing of multiple channels (conference), multi-channel monitoring, and real-time voice playing;
l The volume of voice recording/playing can be adjusted by software, and the AGC is supported.
