1. It adopts dual dsp design, with built-in 24 section A. B dual channel high-precision digital notch filter, which can accurately find the frequency point of howling and eliminate it. At the same time, it has the function of automatic phase shifting and frequency shifting, and has strong howling suppression ability.

2. It is equipped with double 24 segment parameter equalization and high-low pass frequency division to correct different environmental acoustic defects.

3. Line input/output, default is 0db input, 0db output, and can also be set as low level output or high voltage output.

4. It is equipped with 10 scene saving and calling functions, which can save and call 24 segment equalization, howling suppression and notch filter parameters of 10 scenes, and will be automatically saved when next boot.

5. The machine supports computer software control, which can be connected to the machine through USB and adjusted on the computer.

6. It is equipped with 48v phantom power supply, which can set switches in software or machine, and is compatible with dynamic coil and capacitor microphone.
