01 Introduction

●Four channels receive signals, each channel has 50 channels to choose from

Using UHF ultra-high frequency band, there is less interference than the traditional VHF band, and the transmission is more reliable.

●Adopting stable PLL digital phase-locked loop synthesis technology, the performance stability of the whole machine is significantly improved;

●UHF band transmission signal, frequency range 640-690MHz

●LCD screen displays working channel, working frequency, receiving signal, audio signal

●4 rubber receiving antennas are set on the back of the receiver to enhance the received signal, and the appearance is generous and decent;

●There are 4 balanced outputs and 1 mixed unbalanced output on the back, which is suitable for connecting various external devices;

●High-quality microphone tube, strong pickup distance, high-fidelity unidirectional condenser microphone core, sound restoration, high clarity, low noise;

●The microphone consumes 80mA, powered by 1.5V batteries (2 pieces), and can be used continuously for more than 8 hours;

●The microphone head is equipped with a red light ring to indicate the working status of the conference microphone tube.

●Usage distance: 60 meters

●Suitable for various meetings and lectures.
