Product description details / Product description
Lx-2400 automatic high speed frequency shift feedback suppressor
Ultra wide frequency response circuit technology, frequency response up to 20Hz-20KHz, with a unique algorithm to deal with microphone whistling, to maximize the suppression of whistling. When the microphone signal is received, the frequency and phase of the input signal and the output signal are analyzed continuously. If the frequency and phase reach a certain degree of superposition, the signal will be processed intelligently to prevent the occurrence of positive feedback and suppress the howling.
This product has the function of automatic detection of on-site whistling point. The sound is filtered by DSP system, the bass compensation is automatically mixed, intelligent high-speed feedback processing is fully digitized, and the feedback processing is fully digitized. When multiple microphones are used at the same time, it can automatically adapt to the acoustic environment without debugging and quick correction function, so as to ensure the sound quality, reduce the delay, select the high, middle and low input levels, and prevent the loss of peak input, Effectively increase the microphone pickup distance by 30 ~ 100cm
Technical features
1. Ultra wide frequency response circuit technology, no voice change, no metal tail, strong echo suppression.
2. Digital frequency shift technology, super anti howling, smooth and stable sound, no floating and dry hair.
3. Super stability: built in crystal oscillation, software algorithm, good stability, little interference by temperature and external environment.
4. The appropriate audio frequency spectrum can be customized according to the application situation, so as to greatly improve the system gain.
