Enjoy the freedom on stage that in-ear monitors provide, with the Xvive Audio U4R2 wireless in-ear monitoring system. Connect a line-level monitor mix from a return on your stage snake (or from a mixer, music player or computer) to the U4R2 plug-on wireless transmitter, then connect your choice of headphones or in-ear monitors to the compact receivers — two receivers are included. A large volume knob makes it easy to make volume adjustments without looking down at the receiver. And with five hours of battery life, over 90 feet of wireless range, and less than 5ms of latency, Sweetwater can highly recommend the Xvive Audio U4R2 in-ear monitoring system for band applications in small venues.
