Offering a self-managing, plug-and-play 2.4 GHz system that’s scalable to 20 channels and delivers the same dependable, high-quality audio – regardless of where you set it up. Designed for hassle-free deployment, the system overcomes many challenges of conventional wireless microphones, such as frequency coordination, complex intermodulation calculations, and remote antenna cabling.

Seamless setup and management are controlled via Audio-Technica’s Wireless Manager software, which is capable of managing multiple UHF, 2.4 GHz and DECT wireless systems from a single screen. In addition, AES128 encryption comes standard, providing security and reliable operation. The transmitters included in each system are paired and ready to use out of the box, and offer all-day operation on a full charge.
