XviveU45R2 Wireless In-Ear Monitor System
1/15
Independent shopping perspective
The Korena take
The U45R2 sends one mono monitor mix wirelessly to two belt-pack receivers, giving two performers a shared monitoring setup from a transmitter. It accepts XLR or 1/4-inch TS input with an adapter and delivers 24-bit/48kHz audio with 5ms latency. The system operates in the 5.8GHz ISM band, offers six selectable channels, and is rated for up to 100 feet line of sight. Rechargeable operation can continue while charging.
Strong match
Who this is for
- Two performers sharing one mono monitor mix during rehearsal, recording, or live performance.
- Sending a mixer or audio-interface feed to mobile in-ear monitoring.
- Silent-practice setups that route monitoring through headphones instead of external amplification.
Consider the trade-offs
When to look elsewhere
- Performers who need separate mixes from the included two receivers.
- Stereo monitoring setups; the system operates in mono.
