Main features: Broadband transmission (50MHz), segmented reception technology (two independent 25MHz sub-bands): 4 channels of the receiver have 60 independent adjustable channels. The standard 1U metal chassis has a built-in dual-channel receiving circuit, which is sturdy, heat-resistant, and is of professional quality for isolating harmonic radiation interference. Cooperate with the "audio code and radio frequency intensity" mute control to prevent interference from radiation noise from other audio and video equipment. It has an "ACT" automatic channel tracking button. As long as you press the SET button, the transmitter can automatically and accurately lock the working channel of the receiver without causing any errors or malfunctions.
