Xvive U45R4 4 Players Band In-Ear Wireless Monitor System

The U45R4 puts professional wireless monitoring in every band member's hands with zero latency compromise. This complete system ships ready to deploy—one transmitter and four compact bodypack receivers—delivering independent, real-time mixes across a rock-solid 5.8 GHz connection. Built for live stages, rehearsal rooms, and studios where tight ensemble playing demands absolute timing precision.

Wireless Performance & Range

Operating on the less-congested 5.8 GHz frequency band with 25 mW E.I.R.P. RF output power, the system maintains stable coverage up to 100 feet with minimal interference. Six available wireless channels allow up to six independent U45 systems to coexist in the same venue without crosstalk, making it practical for larger events or multiple band setups.

Audio Quality & Real-Time Performance

24-bit/48 kHz digital audio resolution captures full-bandwidth sound well beyond CD quality, paired with a 110 dB signal-to-noise ratio and 0.20% total harmonic distortion for transparent monitoring. Ultra-low latency under 5 milliseconds ensures each performer hears their mix in real time with no perceptible delay—critical for tight ensemble playing.
