Features:
Wireless transmitter receiver system, for Stage performance.
UHF 600-870 MHz band and latest high frequency filter of the RF to avert frequency interference.
PLL system, preset 16 non-interfered channels.
Special design commanding circuit, strongly improve S/N ratio.
Automatic frequency scan feature searches for available frequencies.
Longest distance UP TO 40m
Twice mixer high frequency circuit design, very strong sensitivity.
Using surface amount technology for PCB, more stable function.
The receiver support DC power supply and AA batteries.
