The U4R 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 a single receiver and a single 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.

Featuring dual balanced-armature drivers, the T9 In-Ear Monitors from Xvive are designed to deliver an audio performance rivaling a customized set of earphones, but at a much more attractive price point for musicians and music lovers. The unified crossover has been engineered to ensure that each driver is only sent the frequencies it is capable of accurately reproducing. The low-frequency driver provides powerful mid/bass down to 20 Hz, while the custom-tuned, custom-ported micro tweeter supplies high frequencies up to 16.5 kHz, almost the full range human ears are capable of hearing.

The T9 delivers a clear, natural, and unhyped sound that ensures musicans can trust their mixes and recordings. Audiophiles will appreciate the headroom to accommodate customized EQ settings from source material, letting you boost the bass or dial in more high end without having to worry about distortion. The detachable 3.9' cable connects to a wide range of audio gear and mobile devices via a common 3.5mm TRS connector; a 1/4" adapter is also provided.
