The digital signal processor SMART Filter algorithm in applications running on feedback suppressor in video conference room, meeting room and so the intelligent speed obvious advantages over all other automatic feedback controller to improve the system, the speed of adjustment, automatic adjustment can complete all kinds of parameters of PRE in less than 30 seconds. During the performance, 24bit's PRE will continuously monitor feedback, and never allow it to destroy the performance. The filter can be almost immediately set up (1KHz frequency is within 0.4 seconds)

Each channel has 12 independent digital notch filters, which are automatically controlled from 40Hz~20kHz

Filter bandwidth: the user can control, or 1/10 octave, or 1/5 octave, constant Q, resolution 1Hz

Time needed to find and eliminate feedback: 0.4 seconds, typical ＆#118alue 1kHz

The number of active filters and fixed filters per channel: user selectable, and the last configuration stored in memory

Active filter timer: the release time of active filter is 1, 5, 30 or 60 minutes

Input / output maximum signal level: balanced input / output +27dBV peak, unbalanced +21dBV peak

Input impedance: balanced or unbalanced input impedance >40K ohm, 2 pin high level

Output impedance: balanced or unbalanced output impedance 150 ohms, 2 pin high level

Approach: true power shutoff

Peak space: General 4dBV balanced input, the maximum peak ＆#118alue is +23dB

I/C connectors: XLR-3 and 1/4 "TRS"

Frequency response: 20Hz~20kHz, + 0.3dB

Gain matching: + 0.2dB

Frequency response: + 0.25dB, 20Hz~20kHz

Signal to noise ratio dynamic range: >100dB

Total harmonic distortion: 0.005%, 1kHz; 20Hz~10kHz,

<0.01% 10kHz~20kHz, <0.025%

Dynamic range: >105dB
