Four in  two out
·It uses echo cancellation and reverberation elimination algorithms to achieve the goal of eliminating acoustic feedback.
·Under any usage conditions, a gain of 6dB can be achieved up to 12dB.
·Ultra wide frequency response circuit technology, no distortion, no tail noise, strong suppression
·Digital frequency shifting technology, super strong anti howling, smooth and stable sound, without any phenomena such as excessive or excessive noise.
·Built in 32-bit DSP software algorithm, stable circuit design with good performance, and minimal temperature and external disturbances.
·The appropriate frequency spectrum can be customized according to the application scenario, thereby significantly improving the system gain.
·Equipped with a LCD screen, it can intuitively display the frequency spectrum and working status of the current sound.
·Equipped with a combination of 6.3 and XLR card inputs, it provides a separate 48V phantom power supply with a pre amplifier output and total sound volume adjustment.
·Each channel can be equipped with a static filter, and each channel has parameter equalization. The working frequency is 20-20KHz, and it automatically scans and suppresses howling points.
·Adaptive filters can switch between "fast" mode and "precise" mode.
