UR-112D Dual-channel True Diversity Wireless Microphone


UR-112D series is a dual-channel true diversity wireless microphone, true diversity receiving mode is more stable, automatic signal selection, eliminating receiving dead angle, to avoid the phenomenon of frequency drop. This series is specially designed for singing, with wide frequency response, rich sound quality, roundness and fullness, and powerful vocal expression. Cordioid directional sound pick-up, high sensitivity, while reducing environmental noise pick-up, high fidelity timbre, suitable for karaoke, bars, nightclubs, clubs, and small to medium size performance. 

Key Features:

AFS(Automatic Frequency Selection)

·Press the “AFS”(Auto Frequency Selection) button 3 sec and the receiver will auto-scan and lock on to an open, interference-free frequency.

IR Infrared

·Press [IR] button to upload automatically the receiver frequency to the transmitter.


·PLL(Phase Lock Loop frequency control) design ensures transmission reliability, “NoiseLock”squelch effectively blocks stray RF.

Super Wide Frequency Range

·UHF554-936 MHz operating frequency range, with AFS (Auto Frequency selection) function, dual-channel reception, frequency-selective greater..

·Each channel with 32 adjustable frequencies, total 64 adjustable frequencies for dual channels, 24 frequency groups provides 768 selectable frequencies for users.

Universal Property

·134MHz transmitter, four different frequency bands transmitter can be used at random, which is very convenient for debugging and management.

Signal stability

·The hardware circuit of the whole system is controlled by a microcomputer, and the selected computer technology is used to calculate the frequency of no interference with each other, so that the performance of the whole system is more stable, and it is not easy to occur the phenomenon of frequency offset and interruption.

LCD Display

 ·Bright and easy-to-read LCD display show RF/AF signal strengths, transmitter battery consumption, can set channel, frequency, frequency group, user name, mute level, etc.

Energy Conservation

·Accurate low consumption circuit design, battery life is twice as common one.

UR-112D Dual Channel Wireless Receiver

·EIA standard 1U metal rack receiver chassis.

·Bright LCD display can simultaneously display the working channel or frequency, RF & AF signal status, transmitter battery consumption as well as mute level.
