Features: • CPU built-in audio sampling module, low interference from the hardware circuit, audio signal has low noise. • Smart audio crack protection, auto low microphone sensitivity to meet the requirements of the high volume to reduce audio crack. • Adopts wide dynamic range processing technology for the valid audio signal, balances the processing of high audio and low audio. • High-sensitivity microphone, omni-directional pickup, clear audio, high anti-inference capability, Noise reduction via the algorithm to enhance signal definition. • Auto gain and compensate the human voice frequency. Exaggerates the human voice in environment of lots of noise and can present the clear voice. • It can effectively reduce the indoor reverberation resulting from the reflection via the wall, ceiling. • It supports screaming control function and can greatly enhance the speaker effect when the pickup and the loud speaker are in the same environment. • Built-in high-speed CPU, real-time processing audio signal, low latency. • Built-in lighting protection, power two-polarity misconnection protection, static electricity protection. • CE, FCC compliance.
