· Built in echo cancellation, feedback suppression, noise algorithm
The stable double talk detection method can effectively eliminate the redundant echo even in the strong background noise and nonlinear distortion environment; the noise suppression algorithm can quickly and accurately track the environmental noise changes and maintain good output sound quality.
· Total 10 input signal interfaces, full function audio regulation module
Provide eight mic inputs + two line inputs + four output, support gain adjustment, 48V fantasy power supply, built-in front stage amplifier, signal generator, expander, compressor, 5-segment parameter equalization, 31 segment graphic equalization, delayer, frequency divider, limiter and other functional modules.
· Built in PC control software
The processor has built-in windows platform control software, which can be downloaded and installed after networking. The software design is simple and practical. IOS platform control software has also been launched, and the function experience is constantly being optimized. In addition, we still support the web control mode to provide you with more free testing and debugging experience.
