Xvive U45R In-Ear Wireless Monitor Receiver

The U45R is a compact belt-pack receiver engineered to expand your U45 wireless monitoring system without sacrificing audio fidelity or stage mobility. This unit delivers identical high-resolution performance to the transmitter, letting you scale your setup for larger ensembles, backup vocalists, or multi-presenter configurations while maintaining rock-solid wireless synchronization across your entire rig.

Audio Performance & Wireless Connectivity

24-bit / 48 kHz audio resolution paired with a 110 dB signal-to-noise ratio ensures crystal-clear monitoring reproduction. The 5.8 GHz wireless connection delivers sub-5 ms latency—keeping performers locked in sync during live performance—with a stable signal reaching 100 feet and the ability to run up to six U45R receivers simultaneously in the same area without interference.

Design & Battery Life

The compact molded plastic and cast metal construction fits seamlessly into a belt pack for unrestricted stage movement. A 3.7V rechargeable lithium-ion battery (1200 mAh capacity) provides 5 hours of operation per charge, with a rapid 1.5 to 2.5-hour USB charging cycle that keeps downtime minimal between sets.
