XviveU45R4 Wireless In-Ear Monitor System
1/15
Independent shopping perspective
The Korena take
U45R4 is a four-user wireless in-ear monitoring package built around one transmitter and four belt-pack receivers sharing a mono mix. It accepts XLR or 1/4-inch TS input with an adapter, then supplies a 24-bit/48kHz wireless feed with 5ms latency. Six selectable channels and support for up to six simultaneous systems give it room for larger monitoring arrangements. The 5.8GHz ISM system is rated to 100 feet line of sight, with rechargeable batteries usable while charging.
Strong match
Who this is for
- Bands sharing a single mono in-ear mix across four performers.
- Rehearsal, stage, or studio monitoring from a mixer or audio interface.
- Expanding group monitoring with multiple systems, up to six operating simultaneously.
Consider the trade-offs
When to look elsewhere
- Bands needing four independently controlled monitor mixes from this one-transmitter configuration.
- Stereo monitoring setups; the system operates in mono.
