1. Name: wireless microphone/one for two
2.Technical parameters: One for two wireless microphones.
Main feature: Broadband emission (50MHz),
Segmented receiving technology (two independent 25MHz sub-bands): The handheld channel has 16 independent adjustable channels.
The standard 1U metal case has a built-in dual-channel receiving circuit, which has the professional quality of sturdiness, heat resistance and isolation of harmonic radiation interference.
Cooperate with "audio code and radio frequency intensity" mute control to prevent the interference of other audio and video equipment and other radiation noise, and will never cause errors and malfunctions.
