J-93U Professional High Band UHF Wireless Microphone

*Dual-channel phase-locked loop circuit design. *Digital pilot to prevent the same frequency,adjacent channel interference

Product Feature:

*Dual-channel phase-locked loop circuit design, 200 channels selection, converience to be used for serval device at the same time,  avoid the interference.

*Smart ID recognition technology, automatic frequency modulation technology.

Transmitter will adjust the same frequency according to receiver when the frequency confusing.

*Setting up High and Low power changing funtion, it's converience to be used on meeting, school, KTV room and so on.  Saving battery power.

* Lock at low level funtion in transmitter and receiver, adoid the wrong operation

*LCD display.
