Product description:

Using UHF ultra-high frequency band, lessinterference than traditional VHF band, and more reliable on transmission. Equippedwith Multi-channel frequency synthesis technology of DPLL digital phase-lockedloop, can provide more than 200 channels at 250 KHZ channel space within 50MHzfrequency band. It's convenient for Multiple sets of machines used at the sametime and easy to avoid all kinds of interference. Even if the frequency of emitterand receiver tuning wrong, you just need to press the button, then thetransmitter will automatically lock the frequency of receiver and adjustconsistently according to the advanced automatic frequency hopping technology. High-lowpower switching function, suitable for meeting places (high power emission) ,classrooms and KTV rooms (low power emission) . To save battery power. Equipped with transmitter andreceiver lock function to prevent from incorrect operation. Moreover, you canadjust the sensitivity as needed through the receiver sensitivity adjustment function to improve the capacity ofresisting disturbance and increase the receiving distance. Aexcellent LCD display make the working states more clear.
