The U4RR4 Wireless In-Ear Monitor System from Xvive Audio provides performers and presenters a hands-free, cost-effective, and expandable solution that supplies 24-bit/48 kbps digital sound quality to their favorite in-ear and headphone monitors. This configuration includes four receivers, all able to receive the digital signal from the single included transmitter; ready for plug-and-play use in a wide variety of settings including musical venues and and theatres, houses of worship, schools, corporate conference rooms, and more.

The portable, easy-to-use U4 system features road-worthy components housed in tough molded-plastic and cast-metal chassis built to handle the rigors of touring and designed to work with a huge variety of audio gear. The components are powered by internal non-replaceable batteries that offer 5 hours of operating time and are recharged via USB ports.

The transmitter works with basically any mixer or other device that has an available balanced XLR or unbalanced 1/4″ output jack. Just plug the transmitter in, and it will broadcast the incoming audio to any of its six selectable 2.4 GHz channels. Simply set the bodypack receivers to the same channel and you’re good to go. The system provides a 90′ line-of-sight transmission range and a 5 ms latency, low enough for musical applications.
