无线话筒---主机U702M
★ UHF high frequency band is adopted, which has less interference and more reliable transmission than the traditional VHF band
★ adopt digital phase-locked loop multi-channel frequency synthesis technology, provide up to 200 channel options within 50MHz frequency bandwidth with 250kHz channel interval, facilitate the simultaneous use of multiple sets of machines, and easily avoid all kinds of interference
★ advanced automatic frequency matching technology, even if the frequency of transmitter and receiver is disordered, you only need to press it lightly, the transmitter will automatically catch up with the frequency of receiver and adjust it to be consistent, easy to use
★ LCD screen makes the working state of receiver and transmitter clear at a glanc
