MadBoy® U-TUBE 20R wireless dual channel rechargeable karaoke microphone set



please allow 3-5 days delivery time

Party is going on, but the wireless mics are running low on battery power!

People are full of energy but mics are not...  A familiar situation to anyone who use wireless microphones.
With MadBoy®’s U-TUBE 20R wireless dual channel rechargeable microphone set, battery power will be a thing of the past. 

The set consists of two high-quality microphones, charging unit and receiver with LCD-display. Microphones operate in the safe UHF band 863 - 865 MHz. That operation range will remain in wireless use after the coming range changes in Europe. 
Metallic receiver is made for hard durable gig use. The device's display shows Audio/RF signal and used frequency. From rear panel you can access balanced XLR outputs and unbalanced 6.3 jack output. On/off switch and both channel volume controls are placed on from panel.
Handheld microphones are made of high quality materials. You can feel the quality as soon as you take the microphone in your hand. Sound is velvety soft but at the same time crystal clear. The sound quality is perfect for all kinds of singers and different voices. 

Both microphones are powered by two rechargeable AA-size NiMH batteries, which can be easily replaced if necessary. Microphones are protected by circuits, which prevents annoying pop-sounds when opening and closing.  With the charging unit you can charge both microphones simultaneously or separately, as you want. A light indicates when charging is complete.  
Headset and lavaliere microphones and body pack with instrument cable optional.
