FBC-100

One of the Fastest Feedback Cancelers in the World!

fbc10001

2019午夜75福利不卡片在线FBC-100 is designed for use in wired/wireless microphone systems, conference systems and high quality sound amplifications, which all need to control acoustical feedback.

The acoustical feedback phenomenon is usually called “feedback”, coming from the positive feedback way between the amplifying system and the acoustic pickup (Mic) system. Since its discovery, the feedback issue is a headache to the audio engineer.

2019午夜75福利不卡片在线To solve the “feedback” problem, there are two ways:

  1. Frequency (or pitch) shifting (destruction phase balance condition)
  2. Utilize EQ to reduce the gain of the frequency band which has feedback problem.

For a long time, pitch shifting was used as a feedback canceling method. It presents good feedback cancelling for those systems where sound playback quality is unimportant, but because of noticeable frequency changes, it can not be used in sound quality sense applications.

2019午夜75福利不卡片在线The problem of using GEQs or most PEQs that the band rejection filter is usually not up to standard, so that it will kill the frequency without correcting the feedback problem. On the other hand, utilizing the GEQ or PEQ for feedback cancelling requires an experienced audio engineer with sensitive hearing – even so, it is still a low precision setup for feedback cancelling.

 

FBC- 100 Feedback Canceler

2019午夜75福利不卡片在线FBC-100 uses the newest DSP technology, realizing the fastest automatic feedback canceler in the industry! It only needs around 0.1 Sec (at 1kHz)  to catch up with the origin of feedback to correct the sound. In the following graph, the thin dash is the frequency response curve of the acoustic system after feedback suppression by the FB-100, while the thick line is a normal GEQ feedback suppression.
