Feedback suppressor FB3000

Functional features

Adaptive environmental noise suppression algorithm, high-speed floating point digital audio processor and advanced sub-band Echo Cancellation technology are adopted to completely eliminate noise and Echo at high speed and automatically, and make the live audio send out accurately and clearly in real time.

Built-in adaptive dynamic noise filter can filter out the background noise of the field environment without affecting the transmission of high quality voice signal. System intelligent level control technology, can obtain clear, continuous, signal level without obvious fluctuation of the voice signal. Built-in AGC bi-directional control, with the ability to distinguish between intensified signal and soft signal, to maintain the coherence of speech tone and speech easy to hear clearly, to maintain the comfort of listening, can increase the gain up to 6-15dB.

1. Built-in 24Bit A/D, D/A conversion; A 24-bit DSP processor, a 48kHz sampling high-speed floating point digital audio processor, and the most advanced sub-band Echo Cancellation technology can effectively eliminate echoes and noises.

2, Fully automatic operation of the working mode, no manual debugging, no matter the room environment position, temperature, humidity, decoration change, system installation without sound field debugging, accurate and reliable simple use.

3, Built-in adaptive dynamic noise filter, can filter out the background noise of the field environment without affecting the transmission of high-quality voice signal. Improve signal-to-noise ratio, improve sound quality.

4, Built-in AGC automatic gain control, you can get a clear, continuous and stable voice signal.

5, Built-in digital high and low pass adjustment control, can limit the sound of language audio

6, Built-in digital pressure-limiter: can improve the distance of picking up sound

7. Built-in 10-segment graphic equalizer: more accurate frequency control

8, each function can be set through the machine or connected to the computer
