FU-SERIES 3 IN One Karaoke Power Amplifier

FU-3300/3500/3700 Specification:

◆The industry's first patented automatic hand sensing technology, the microphone automatically mutes within 3 seconds after it leaves the human hand and stops (in any direction).It can be placed at any angle), it will automatically save energy and enter the standby state after 5 minutes, and it will automatically shut down and completely cut off the power after 8 minutes.

A new concept of intelligent and automated wireless microphone

◆Digital pilot technology, never cross-frequency

◆UHF frequency band, phase locked loop (PLL) frequency synthesis

◆32 channels, channel spacing 1 MHz

◆The microphone uses Tesco’s AA battery, with a battery life of 5-8 hours

◆The microphone adopts a unique boost design, and the drop in battery power does not affect the overall performance of the microphone.

◆The ideal environment operating radius is 30 meters, suitable for consumer occasions such as families, teaching, and civil groups

◆Zinc/aluminum alloy microphone tube body

◆ Equipped with shake-shake frequency matching function, which can quickly synchronize the microphone to the working channel of the receiver
