Product Features  
• This device employs a powerful DSP system that actively filters out the howling feedback signals and eliminates them before feedback occurs, ensuring the original signal remains unaffected. Under normal usage conditions, the device requires no manual adjustment and automatically adapts to the acoustic environment (the adaptation process takes approximately 5 seconds). The entire system gains an additional 6~12dB of amplification.
