KTV microphone screech feedback suppressor product Recommender

K-600KTV screech suppressor sound reinforcement project of acoustic feedback is a sound sector comparisons difficult issue. Imported feedback suppressor prices, the domestic present simulation move larger prescaler distortion, K songs effect is not very satisfactory. Independently developed DSP digital FSK technology and specialized applications for KTV sound field design, aims to apply DSP digital signal processors and microcontrollers, the audio is digital FSK, while bypassing the cumbersome and complicated parameters balanced (Note: the parameters of isostatic adjustment in the improper sound quality degradation is very large), the software automatically search Whistler points and automatically notch, anti-whistling stronger, wider frequency response range, distortion smaller. Can better elimination and solve the speakers to be caused by the microphone self-excited screech, improve and enhance the microphone gain, meet the requirements of the KTV sound reinforcement. The main products include audio signal input circuit, A/D converters, DSP digital signal processor, D/A converters, bandpass filter, the output amplifier circuit, whistle signal processing circuits, microcontrollers, display unit circuit, press the input circuit, etc. This utility model with DSP-shift control, move to frequent sound better, distortion is very low, undulating tone and metal sounding muddy, displaying perfect, manipulation, solve and eliminate speaker back from the microphone self-excited screech, significantly improve and enhance the microphone gain, to meet a variety of sound reinforcement system requirements. Product features: 1. Super anti-whistling function: using DSP digital shift and automatically notch technology, the perfect solution to the issue whistling KTV. 2. the kernel using DSP, 24bitA/D conversion, 96K sampling rate, guarantee perfect sound quality. 3. dramatically increase microphone gain, singing easily. 4.DSP shift in sound feedback when approaching the excessive vibration, not suddenly, protect the system. 5. all digital control with LED and the digital display, easy manipulation. 6. Auto search and memory frequency howl, eliminating many debugging problems. 7. a memory function, automatically restore again. 8. protect the power amplifier and speaker, K field management easy, boss assured. b
