1. Built-in 4 x 4 AES67 network audio module can output 4 signals to different application scenarios such as live sound reinforcement, remote conference, recording, etc. 2. POE/DC-12V dual backup power supply. 3. Built-in DSP audio processing: high and low pass, up to 11-band PEQ, noise gate, compression. 4. It has high-performance independent dual-mode feedback suppression (limited wave filtering and adaptive filtering, with an adaptive filtering guarantee of 9dB improvement in sound transmission gain). 5. It has adaptive noise reduction ANS (noise reduction capability of 15dB). 6. It has adaptive echo cancellation AEC (20-20K, echo cancellation capability greater than 65dB, convergence speed greater than 35dB/S, tailing time 128ms). 7. Support customization of DSP functions for each channel. 8. Built-in headphone interface, supporting simultaneous interpretation. 9. The processing algorithm is fully enabled, with a latency of less than 8ms. 10. Support automatic restoration of all configurations after power failure and network disconnection.
