FS-302 2-input 1-output Fully Automatic Digital Feedback Suppressor

Description

It employs echo cancellation and noise reduction algorithms to effectively eliminate room reverberation, thereby achieving the goal of eliminating acoustic feedback. By adding noise suppression (unheard noise) to the output signal or changing the frequency of the output signal by 5 Hz, the feedback suppressor can detect the components in the signal that cause reverberation and remove them before feedback occurs, while maintaining the integrity of the original signal. Number of input channels: 2 channels (2-channel balanced line/microphone input or choose 2-channel 6.35 non-balanced input). Provides a 48V phantom power supply switch selection module, which can supply power to 2 microphones.
Features and advantages:
★ No need for adjustment, automatically adapts to the acoustic environment;
★ Can achieve a maximum gain of 6dB up to 12dB in any usage situation;
★ Regardless of how many microphones are used, the effect remains excellent;
★ Fully automatic, no need for adjustment, zero maintenance.
★ Eliminate feedback before it occurs
★ Automatically adapt to the acoustic environment
★ 2-channel balanced line or microphone input, provides phantom power
★ Adaptive filter can be converted between “fast” mode and “precise” mode.
★ Fast mode is suitable for occasions where the microphone position frequently changes:
For example, in a discussion system equipped with multiple switching microphones. Precise mode is suitable for occasions where the microphone position is fixed.
For example, in a lecture platform with a complex acoustic environment.
The adaptive filter can converge at a slower speed, thereby suppressing more reverberation components.
★ Built-in automatic mixer to achieve priority function.
Technical features:
★ 1. Ultra-wide frequency response circuit technology, no sound distortion, no metallic tail tone, strong suppression of echoes.
★ 2. Digital frequency shifting technology, strong anti-crowd noise, sound round and stable, no drifting or dryness phenomena.
★ 3. Super stability: built-in crystal oscillator, software algorithm, good stability performance, very little affected by temperature and external interference.
★ 4. Can be customized with an appropriate audio spectrum according to the application environment, thereby significantly improving the system gain.
