Product Description
Stage Performance Wireless UHF Microphone Dual Channel
KT-4D lavalier headset microphone
System Features1.True diversity receiving system has excellent anti-interference performance, strong signal receiving ability.
2.Professional phase-locked loop(PLL) circuit match up with noise lock squelch control technology and digital pilot technology, digital pilot control will make AF signal to be mute to restrain noise when transmitter turn off, meanwhile receiver is mute to cut off interference signal.
3.LED display screen indicate system volume, power, channels A/B switch, working frequency, channels, receiving distance gear, system lock key, etc.
4.Display screen will become red color to alarm when transmitter is closed, this effectively help to offer instruction.
5.Full-automatic search frequency function effectively locks the strongest signal in the working environment.
6.Each channel has 3*10 bit LED light indicate A/B RF signal's strength and level signal strength, clear to see working condition.
7.Adopt electronic volume control which has higher accuracy eliminate potentiometer's resistor noise.
8.Adopt FULINDA's "Audio Reference Compression" patent technology, with great dynamic response and excellent tone quality.
9.This true diversity system is designed for tour and fixed installation and provide multi-sound microphone heads to replace.
10.Receiving distance has HI, MID, LOW three gears to adjust based on different working environment.System SpecificationReceiver
