Xvive U45R4 Wireless In-Ear Monitor System

Wireless in-ear monitoring systems must deliver both reliable RF performance and consistent audio quality for group use. The Xvive U45R4 wireless in-ear monitor system provides 24-bit/48kHz audio with ultralow latency under 5ms, supporting responsive monitoring across live performance, rehearsal and studio applications. Operating on the 5.8GHz frequency band, it maintains a stable, interference-resistant connection with a range of up to 100'. This complete system includes one transmitter and four belt-pack receivers, making it well suited for full-band IEM monitoring with multiple performers sharing a single mix.

High-Resolution Audio With Stable Wireless Operation

The U45R4 system delivers a full 20Hz–20kHz frequency response with low distortion and a clean, detailed signal for accurate IEM monitoring. Its 5.8GHz wireless platform avoids the congestion commonly found in 2.4GHz systems, helping maintain consistent performance in busy RF environments. With six selectable channels and support for multiple systems operating simultaneously, it scales effectively for bands and larger monitoring setups.

Flexible Monitoring for Performance and Practice

This Xvive wireless IEM system supports a range of monitoring scenarios, from sending a mix from a mixer or audio interface to in-ear monitors to expanding coverage with additional receivers. It can also be used for silent practice setups, allowing bands to rehearse without external amplification. This flexibility makes it suitable for live performance, rehearsal spaces and content creation environments where consistent monitoring and mobility are important.

Compact Design With Rechargeable Operation

The compact transmitter includes both XLR and 1/4" inputs for integration with common audio sources, while the lightweight belt-pack receivers feature standard 1/8" headphone outputs. Internal rechargeable batteries provide up to five hours of operation and can be charged via USB, including during use. This streamlined design supports quick setup, reliable performance and efficient operation across a range of applications. Designed for bands and performers who require dependable multi-user monitoring, the Xvive U45R4 wireless in-ear monitor system provides a reliable and scalable solution for IEM applications.
