UHF Wireless Microphone System
Main Features:
u Broadband transmission (50MHz), segmented receiving technology (two independent 25MHz sub-bands): each of the 4 channels of the receiver has 60 independent adjustable channels.
u The standard 1U metal case has built-in dual-channel receiving circuit, which has the professional quality of sturdiness, heat resistance and isolation of harmonic radiation interference.
u Cooperate with "audio code and radio frequency intensity" mute control to prevent the interference of radiation noise from other audio and video equipment.
u With the "ACT" automatic channel lock button, as long as you press the SET button, the transmitter can automatically and accurately lock the working channel of the receiver without any errors or malfunctions.
