Aubern Feedback Suppressor FBD-2630
FBD-2630 adopts function of echo cancellation and elimination of reverberation to effectively flter room reverberation, in order to achieve the purpose of eliminate acoustic feedback. By adding shielding noise (inaudible noise) to output signal, or changing the frequency of the output signal by 5 Hz, the feedback suppressor can detect the component that causes reverberation in the signal and remove it before the feedback occurs, while maintaining The initial signal is intact. Number of input channels: 2 channels (2 channels of balanced line/microphone input or 2 channels of 6.35 unbalanced input). 48V phantom power switch is provided, which can provide power for 2 microphones.
TECHNICAL FEATURES
- Ultra-wide frequency response circuit technology, no sound change, no metal tail, strong suppression of echo.
- Digital frequency shift technology, super anti-whistle, mellow and stable sound, no ?oating and dry phenomenon.
- Super stable : Built-in crystal oscillator, software algorithm, stable performance, little temperature and external interference.
- The appropriate audio frequency spectrum can be customized according to the application, thereby greatly improving the system gain.
- No need to debug, Automatically adapt to the acoustic environment (a gain of 6 dB can be obtained under any situation, up to 12 dB.
- 2-Channel balanced line or microphone input, providing phantom power.
- The adaptive ?lter can be switched between “Fast” mode and “Precise” mode (Fast mode is suitable for occasions where the position of the microphone change frequently).
- Built-in Automatic Mixer to achieve priority function.
