Product Description

Digital Feedback Destroyer

Specification of technical parameter
The AFS-2000 adaptive filters can switch between "fast" mode and "precise" mode.Fast mode is apply to microphone position often change of occasion,for example, Equip with multi-channel microphone and switch of the meeting system. Precise mode is apply to the occasion of microphone fixed position.
For example, relatively stable pulpit of acoustic environment. Adaptive filters can be at a slower speed convergence, thus effectively inhibit more reflection component. Before acoustic feedback to happen, can be get more than 12dB gain, Depending on the acoustic environment and the selected mode of operation.

Front panel introduction


1,Power Switch.
2,Bypass/working switcher, if the BYPASS is light , it is in the state of bypass, or if the ACTIVE is light , that is in the state of working.
3,Fast calibration button, if the CALIBRATE is light, it is in the state of rapid correction.
4,Automatic Mixing, if LED is light, means the function of automatic mixing is starting.
5,Input level indicator.
6,Input signal overload indicator, if OVERLOAD is lighting, means should turn down the input level, Avoid signal distortion.

Rear panel introduction



1,Mic 1 balanced input XLR and 6.35 interface.
2,Phantom power supply switch.
    Note: when the switch hits ON,the microphone inputs 1 and 2, the XLR karon interface provides phantom power, and the 6. 35 interface does not provide phantom power.
3,Mic 2 balanced inputXLR and 6. 35 interface.
4,Microphone treble attenuation and lifting knob.
5,Line input lotus interface.
6,Line output lotus interface.
7,Microphone balanced outputXLR and 6.35 interface.
8,Microphone input sensitivity select switch,respectively: high, medium and low.
9,Powerinput, AC220V.


Many Mic Use Mixer such as AUX connecting way Specification:
  Connecting the Mic with 1-N channel(1-5 channel) on the mixer, Put the 1-5 channel of potentiometer turn on( suitable volume), turn off the 1-5 channel fader, that means use the potentiometer to control the volume of 1-5 pieces mic, And then turn on the main volume, Again from AUX output interface (6.35 interface) output signal to the input interface of feedback destroyer, The signal of Feedback destroyer output interface received 6 channel from the mixer, This 6 channel must turn off AUX potentiometer, and throw up the fader, That means, with 6 channel pusher to control the output volume of feedback destroyer. The total output signal of mixer connect with the input of amplifier,and amplifier out to speakers. 
  The volume of whole system mic are controlled by AUX,The volume of feedback destroyer is controlled by the 6 channel fader. If one of the 1-5 channel mic no need with the feedback destroyer function, please turn off AUX potentiometer where it is , and throw up the fader where it is. The benefits of this kind of connection is the background noise of the whole system can get
the maximum control, The noise of the microphone large can down AUX potentiometer, Push a bit bigger fader, Feedback destroyer of great background noise can turn down the pusher, throw up a little AUX potentiometer. So that we can effectively achieve the maximum sound pressure of the whole system, meeting the best effective to achieve.
