Product Description


8-ChMPEG-2/H.264标清编码器

自适应回波抑制器ICS


Gospell GT-5950 The adaptive echo suppressor developed by our company fully supports all terrestrial digital and mobile TV standards including DTMB, CMMB, DVB-T / H, DVB-T2, ISDB-T and ATSC-T Widely used in different power, different types of transmission with the same frequency transmission stations, full support for VHF, UHF frequency range and common digital TV channel bandwidth, but also support extended band and user-defined signal bandwidth.

This product uses adaptive echo cancellation technology, automatic, adaptive to solve common self-excited transmission point with the same frequency transmission patch point, greatly reducing the difficulty of installation and network construction costs, to respond to dynamic changes in the echo, With a wide range of echo cancellation, echo suppression and other characteristics.
