VT-UR3500 True diversity wireless microphone UAE – Dubai Professional performance microphone true diversity series

1. Name: True diversity wireless conference microphone/one to two
2. Technical parameters: One-to-two conference true diversity wireless gooseneck

microphone. Main features: Broadband transmission (50MHz), segmented reception

technology (two independent 25MHz sub-bands): 2 channels of the receiver each

have independent 100 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. Wireless gooseneck

microphone receiver technical parameters: Panel display: LCD liquid crystal display,

which can simultaneously display RF/AF signal strength, channel, frequency, mute

level and other functions; Oscillation mode: PLL phase lock frequency synthesis; RF
