High-Performance 2.4 GHz Digital Wireless System with Handheld Microphone and Dual-Mode USB Receiver. Once again we broke the affordability barrier - with our new ULTRALINK ULM300USB Wireless Microphone System. Now you are free to work the room to your heart's content, without the hassle and restriction of cables underfoot. Highest-quality sound is provided by the dynamic hand-held mic thanks to the built-in transmitter, which operates in the license-free 2.4 GHz range. The dedicated ULM receiver not only connects to your PC/Mac computer's USB port for recording directly into your favorite DAW application, but also works with a wide range of BEHRINGER "Wireless-Ready" mixers and powered speakers - for the ultimate in versatility. State-of-the-art transmitter and receiver operate in the 2.4 GHz frequency band, which is well out of the way of TV stations and cell phone towers, two of the main culprits that wreak havoc in the wireless zone. And because it is digitally encrypted, your signal gets through in all its pristine, high-definition quality, without the random artifacts that often plague other wireless systems. Replacing batteries in wireless mics can get expensive really fast - and having them die in the middle of your set can be a real showstopper! That's why we devoted extra time in developing the ULM300USB to ensure that battery life was extended as much as possible. You get an honest 24 hours of performance time from a pair of AA alkaline batteries, which are available virtually anywhere on the planet. We wanted the ULM300USB to be ultra-easy to operate, so we gave each mic easy-to-understand and operate Volume buttons right on the microphone body. And should you accidentally wander into the "Feedback Zone", we included a handy Panic Mute function that engages when you press and hold the Volume Down button. Operating in the 2.4 GHz band allows your ULM300USB Wireless Microphone System to be used across the globe without any special licensing requirements.
