This is the Xvive Audio U4R Wireless Receiver for the U4 System. You can connect a line-level monitor mix from a return on your stage snake (or from a mixer, music player or computer) to the U4 wireless transmitter, then connect your choice of headphones or in-ear monitors to the compact receiver, and you're ready to rock 'n' roll.

Your whole band—up to six musicians—can use the system together! There can be one monitor mix per transmitter, so if you have multiple U4 sets, you can customize monitor mixes for each band member. This is an easy, great-sounding and cost-effective monitoring solution for studio recording, rehearsals or live gigs. In rehearsal, this also means that there’s no need for PA speakers—so a band can practice in an apartment, or late at night.
