Very high quality Professional UHF microphone system


One Year Limited Manufacturer Warranty in USA

The MUSYSIC MU-U4L 4-channel lapel/lavalier & headset wireless microphone system means that your days of passing the mic are over. Putting this system in your rig is an awesome way to get up to 4 wireless mics going simultaneously, on 4 discrete UHF channels, anywhere and anytime. The MU-U4L is for very high quality professional and reliable 4 channel UHF wireless lapel/lavalier & headset microphone systems. It uses the most advanced technology called SMT (Surface Mounted Technology) and is made of the highest quality surface mounted components to ensure its quality and reliability. It’s ideal for professional performance, in church or home karaoke use.

Four Mics for Four Voices:
Now you can distribute wireless lapel/lavalier & headset to all the singers in your band. You can host panel discussions and send lapel/lavalier & headset down either side of the room to take questions and answers from the audience. Perhaps you're an event planner who needs to make sure that wireless microphones are always in the right places at the right times. Or perhaps you're simply hosting the most insane karaoke sing-along party of all time. No matter what you're doing with 4 separate channels of wireless power, the MUSYSIC MU-U4L will make sure that everyone gets their time on the mic. 

Four Channels, All The Time:
Each of the 4 channels can operate on one of four distinct frequency ranges. This means that the MUSYSIC MU-U4L system gives you the ability to run all 4 channels at once without any fear of frequency interference. Also, it's fully FCC compliant, and is designed to be well shielded against external interference. 

Four Individual Volume Knobs and 1/4" Outputs:
Each microphone channel has its own discrete volume control on the front panel of the rack mountable receiver, to make sure that every voice is dialed into the overall mix correctly in situations musical or otherwise. Each mic also tests out at around 12 hours of total battery life, meaning that you won't have to change the batteries halfway through the performance, meeting, etc. The 4-channel receiver fits in a single rack space. In addition to four separate 1/4" outputs on each channel, the receiver has a single 1/4" TRS or XLR output that sends the mix of all four mics out over one simple connection -- great for plugging in a portable speaker.

Get Mic-Happy:
Getting away from cables is liberating. And a wireless microphone feels great in any situation. But as soon as you start using one, you'll quickly discover that everyone around wants one too. So jump ahead of the curve and get a system that offers maximum flexibility not just for you, but your colleagues and fellow musicians alike.
