•  high-quality 24 - bit, ∑−△ AD / DA, 48kHz sampling rate, I2S digital audio format.
•  high-performance ARM with Embedded operating system; internal 32-bit DSP processing.
•  Stereo or independent dual-channel processing.
•  Per channel has 12 programmable filter, it has a unique mechanism of feedback suppression that can quickly find howling, the processing time is less than 0.4S.
•  Fixed and programable filter, the default 9 fixed, 3 programable.
•  Narrow-band filter bandwidth of 1 / 10 octave.
•  Password protection.
•  Built in shift frequency modules, without affecting the voice of the circumstances, can greatly enhance audio gain.
•  The standard XLR, 6.35mmTRS balance between input and output.
•  Frequency response: 20 Hz ~ 22kHz
•  USB or RS485 remote control ,light isolated communications ensure perfect sound quality (including PC software that has handsome interface and  convenient operate).

   This is currently the most powerful Feedback Destroyer, The max boost gain = 15 dB. It can apply to the meetings, teaching, stage, entertainment, bars and other environmental PA.
