PU-2955 True Diversity UHF Wireless Microphone

Characteristics:

This model adopted the latest intelligent technology, the PCB is better designed, 

which makes the sound with higher fidelity.

Wide band frequency (600MHz-850MHz), total120 channels, interval of each 

channel is 250KHz.

True diversity 2-group independent receiving circuits designed, reduce the external 

signal interference, the receiving distance is farther.

The handheld microphone with smart MUTE function. When the microphone is 

put on the desk or drop down, 3 seconds will enter in MUTE status, without any 

use in 10 minutes, it will be off automatically. If long press the switch to turn on 

the microphone, the “MUTE” disappear on the screen, the MUTE function is off.

The receiver has one key operation, it is very convenient to use.

The receiver has automatically search frequency function, can search the cleanest 

frequency for each microphone faster and better. 

Adopt the sync IR frequency technology, the frequency of the transmitter is 

received automatically by the IR signal and synchronous with the receiver. 

The signal is stable and the anti-interference capacity is enhanced.

The real digital wireless microphone (voice and signal are fully digital encrypted 

transferred), strongly confidential transmission, ensure the microphones sound 

with higher consistency.

Each channel has an independent ID code, the same frequency points from 

outside will not interfere with the receiver.

The receiver use the colorful LCD screen, can choose to show the working 

frequency or channel, synchronously display the microphone battery capacity 

and the microphone output volume and so on.

The receiver with 10 SQ control and visual display on the screen.  

Microphone cartridge, the capacity of climate resistance is strong and the stability is good
