VT-UR4300 4 Channels UHF wireless microphone UAE – Dubai UHF Wireless microphone

1. Name: wireless microphone/one to four
2. Technical parameters: One to four wireless microphones. 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. Wireless

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 – locked frequency synthesis; RF stability: ±0.005 %(-10~50 ℃);

Carrier frequency band: UHF 500~950MHz (standard: 640~690MHz);

Frequency bandwidth: 50MHz; Frequency adjustment: ∧ / ∨ Select the

required frequency, and then press the “SET” function button. It can

immediately make the transmitter automatically lock the same working

channel of the receiver. Reception method: secondary frequency

conversion reception; sensitivity: when the offset is equal to 40KHz and

the input is 6dBV, S/N>80dB; maximum offset: ±68KHz with volume

expansion; comprehensive S/N ratio: >105dB(A); Comprehensive T.H.D.:

<0.5% @ 1KHz; Comprehensive frequency response: 50Hz~18KHz ±3dB;

Maximum output voltage: independent balanced: +10dB(2.5V)/600 Ω,

hybrid unbalanced: +4dB(1.25V)/5K Ω. Mute control mode: dual mute

control of “tone code and radio frequency intensity”; DC power supply:

12V/2A; wireless microphone transmitter technical parameters: anti –

mobile phone signal interference design; metal tube material; oscillation
