200-280mHz Wireless Digital Display Microphone Mic System for Karaoke KTV Audio Player

Features:

 

Using VHF 200-280 mHz band to avert interferencing frequency

Using multilevel high frequency and mid frequency narrowband filter, so as to dispel anypossible interferencing signals

The wireless microphone use hidden antenna look good and are useful

There is a volt indicating circuit in the the microphone. it can tell you if it is necessary tochange the battery

Specially designed circuit switch is on the phone. it is for clearing up waves of miscella-neous siona

All use quartz crystal oscillating circuits so the frequency is very steady

This kind professional wireless microphone adopt a series of measures to improve its functions advance frequency

Using multilevel high frequency and mid frequency narrowband filter, mulriple no-e detect and control

Designing it special functions(tone key locked identity )to a-void interference from outside

Effective, built-in spherical wind
