Product characteristics：

· Built in feedback suppression, noise algorithm

The multi-point filter and multi subband frequency shift technology maintain the harmonic nature of the original pitch period, and will not cause sound distortion; through the acoustic modeling of the room feedback path, the acoustic feedback can be adaptively eliminated; the noise suppression algorithm can quickly and accurately track the environmental noise change and maintain good output sound quality.

· Two channel MIC input

Two microphone interfaces are provided to support gain adjustment and 48V phantom power supply. Increase the flexibility of users' use, and meet users' use needs to the greatest extent.

· Plug and play, portable operation

The pre-set scene, without software adjustment, plug and play, has strong universality, flexible and convenient deployment, greatly reducing the difficulty and cost of engineering wiring.
