Handheld Dual Professional Wireless Microphone Kareoke KTV System

Features: Multilevel, narrow-band, high frequency and intermediate frequency selective filtering are adopted to eliminate the interference signal. Using audio compression expansion technology, the noise is greatly reduced and the dynamic range is increased. Use a special ALC circuit, don't worry about the volume is too large and distortion. With low voltage design, battery voltage reduction still works. Ad hoc handheld microphone switch noise shock wave cancellation circuit. Quartz oscillation circuit is adopted, which has very high frequency stability. Handheld microphone with low voltage, often bright indication circuit, intelligent prompt change battery. Equipped with acoustic feedback, anti whistle function, can effectively reduce the back howling. With separate outputs and mixed outputs, it can be connected to the mixer and the Cara OK amplifier. Automatic level control is adopted to avoid excessive volume and distortion. With low power consumption components, the battery has long service life. Handheld microphone invisible antenna, beautiful and practical. Let a unique noise squelch function, external interference refused to open the machine we sound system. The selection of excellent chips and quality components makes the machine's sound quality excellent. The receiver adopts multi-stage high frequency amplification with high sensitivity. Audio output in balanced and unbalanced mode.
