YUEPU RU-D220 UHF Handheld Karaoke Microphone Wireless Professional System 2 Channel Frequency Adjustable Cordless For Church

 

Frequency adjustment is a most important function for the age of wireless microphone systems that from frequency fixed to evolve to strong anti-interferences frequency changed. No matter many rooms that use RU-D220 simultaneously, frequency adjustment function is the most strongest support to allocate the frequency points to every working system. RU-D220, Stronger, better on it.

Features：

1 Dual channel dual antenna receive signal design, each channel has 100 selectable channels          

2.UHF band transmission signal, the frequency range in between 650MHz-690MHz, the signal step up between the 250KHz          

3 Receiver and transmitter are equipped with VA Holo LCD display, working state at a glance          

4 The back of the receiver is equipped with 2 rubber antennas to enhance the received signal and highlight the appearance of high-grade          

5 Contained one 6.3mm outputs and one balanced output, suitable for connecting a variety of external devices          

6 Microphone power consumption is 130mA, using 1.5V AA*2 rechargeable battery power supply, can be used for more than 6 hours          

7 Using distance: about 100 meters          

8 Audio and data use 32bit encryption transmission and independent ID code, effectively prevent crosstalk and interference          

9 Transmitter and receiver use 8bit encryption infrared transmission synchronization mode          

10 The receiver can observe the battery working state of the transmitter with a glance          

11 Use high fidelity moving coil microphone capsule, so that your voice is more clear and real          

12 The microphone system contain the features of intellgent mute function when you press and hold the power button to turn on the handheld microphone until the "94ON" shows on the screen, the intellgent mute on. You don't need to worry about the microphone drop, that will not occur the harsh sound because of the microphone mute during droping. And When the microphone stay on the table for 5 second, it will mute automatically. When over 5 mins, it will be turn on automatically.
