◆ superheterodyne secondary frequency conversion design, with high receiving sensitivity

◆ the RF part adopts multi-stage high-performance dielectric filter, with excellent anti-interference ability

◆ the first if uses the sound meter filter, and the second if uses the three-stage ceramic filter, which improves the anti-interference ability

◆ specially designed mute circuit can completely eliminate the impact noise of microphone opening and closing

◆ the microphone uses the No.5 battery that is easy to buy and lasts for 6-10 hours

◆ the microphone adopts a unique boost design, so the battery power will not affect the overall performance of the hand microphone

Ideal operation radius of 80m, suitable for all kinds of occasions

◆ the default configuration is a microphone tube with LCD blue backlight and aluminum alloy

◆ it has adjustable transmission power and adjustable squelch threshold. The receiver rear panel is equipped with external squelch control knob, which can flexibly set effective operation radius between 10m and 80m as required

◆ with the function of infrared automatic frequency matching, the microphone can be quickly synchronized to the working channel of the receiver

◆ KTV engineering special model, two microphones, one host. Easy configuration of more than 100 KTV rooms, unique product structure design, fast and simple maintenance.
