Technical parameter
Frequency response: 80~18KHz adopts dual antennas, dual reception lines, and true diversity reception method;
A brand new single channel digital automatic selection long-distance microphone with lD encryption, which is not easily disturbed and will not cause frequency hopping;
Automatic cleaning frequency, self setting switch lock, intelligent feedback, self setting panel function lock, safe use;
The receiver channel has an independent 2000 channel adjustable panel display;
7-bit LED light displays RF/AF signal strength, LCD displays chartreuse when not on, blue when in use, and white when in set status;
Multiple functions such as automatic signal selection, channel, frequency, transmitter battery level reception sensitivity, mute level, etc;
Adopting a unique CPU control switch, the transmitter or receiver has no impact sound no matter what state it is in;
Adopting professional secondary frequency conversion and multi-level RF filtering technology, multiple sets of use do not interfere with each other, and the audio code and RF strength are double silenced to eliminate interference;
The transmitter has a locking mode to avoid incorrect shutdown
