        Adaptive filter can be switched between "fast" mode and "precision" mode. Quick mode suitable for the occasion microphone position changes frequently, for example, is equipped with multiple microphones and conference systems used in the switch. Exact mode is suitable for fixed microphone position occasions, such as the acoustic environment is relatively stable pulpit.
     
    Adaptive filter can converge at a slower speed, thereby more effectively suppressing reflection component. Before acoustic feedback occurs, you can get up to 12dB of additional gain, depending on the operating mode and the selected acoustic environment.
     
           Feedback Suppressor also built two microphone inputs automatic mixer. In many cases, for example in the lectern, pulpit or conference table, two microphones can use to better capture moving the speaker's voice, and this often increases the risk of acoustic feedback. In view of this problem, feedback suppressor Automix will automatically reduce the microphone input signal weaker gain, while increasing the signal input of another strong gain of the microphone. Thus, it can track the movement of the speaker, to produce the best sound clarity. Meanwhile, since the total gain remains constant, thus maintaining the remaining amount of the maximum gain of the acoustic feedback is not generated. Even disabled feedback suppressor, automatic mixer function works.
