Xvive U4R4｜2.4GHz Wireless In-Ear Monitoring System, Single Transmitter Four Receivers

A wireless in-ear monitoring system designed for four-person stage performances, rehearsals, and monitor distribution

Xvive U4R4 Wireless IEM System is a wireless in-ear monitoring system from Xvive, featuring 2.4GHz wireless transmission, less than 5ms latency, an operating range of over 90 feet, and about 5 hours of battery life. Its single-transmitter four-receiver configuration meets the simultaneous monitoring needs of four users.

Compared with traditional wired headphone monitoring, the Xvive U4R4 uses a lightweight transmitter and four beltpack receivers to provide greater freedom of movement on stage. Compared with entry-level monitoring systems in the same class, the advantages of the U4R4 wireless in-ear monitoring system are fast deployment, an intuitive and easy-to-use mono monitoring architecture, and the practical efficiency of one system serving four performers at the same time.

適合誰購買

Performers in four-piece bands who need to share the same monitor signal and want to quickly set up a multi-user wireless monitoring workflow with one system
Members of church worship teams, school music clubs, or event performance crews who want to reduce cabling complexity while providing stable monitoring for four members at the same time
Users in studios or rehearsal rooms who often need multiple people to monitor simultaneously and want singers, drummers, guitarists, and bassists to move freely

誰不適合購買

Professional touring teams that already need multi-user stereo monitor mixes, advanced channel assignment, and large-scale RF management
Entry-level users who only plan to monitor one or two users and want to keep the overall budget as low as possible

Xvive U4R4 Core Technologies and Features

2.4GHz wireless monitoring architecture: Operates in the 2.4GHz band for fast deployment, making it suitable for small gigs, rehearsals, and mobile monitoring applications while eliminating the movement limits of traditional wired monitoring.
Low-latency real-time feedback: System latency is under 5ms, effectively reducing the time gap felt during playing and singing so rhythm, articulation, and performance response feel more natural.
Operating range over 90 feet: Provides wireless transmission over 90 feet in clear line of sight, enough for most small stages, church platforms, and rehearsal spaces.
Mono monitoring design: Uses a mono monitoring architecture, making it easier for users to get a simple, clear, and practical personal monitor signal from the mixer.
XLR transmitter input: The transmitter includes an XLR input and can connect directly to mixer outputs, stage sends, music players, or computer line-level sources with high integration flexibility.
Four-receiver configuration: This set uses a single-transmitter four-receiver design, allowing one transmitter to feed four receivers at the same time, especially suitable for four members sharing the same monitor content.
Intuitive beltpack receiver operation: The receiver is compact and suitable for clipping to a belt or clothing, with a large volume knob for quick blind adjustments during performance.
Rechargeable lithium-ion battery: Both transmitter and receiver are powered by rechargeable lithium-ion batteries, providing about 5 hours of continuous use per charge, enough for typical performances and rehearsals.
Fast setup and high portability: Compared with traditional large IEM systems, the U4R4 is lighter, requires less cabling, and is easier for mobile performers and small-to-medium ensembles to use.
6 selectable frequencies: The system provides 6 available frequencies, making basic configuration and interference avoidance easier when multiple systems are used together.

2.4GHz Wireless Transmission System

Uses a 2.4GHz digital wireless transmission architecture, eliminating complex frequency planning and allowing you to get into rehearsal or performance quickly.
Suitable for small-to-medium stages, churches, event hosting, and rehearsal spaces, balancing deployment efficiency with practical freedom of movement.

Low-Latency Mono Monitoring Design

System latency under 5ms reduces the time gap between performance and monitoring, improving live performance stability.
The mono monitoring setup makes it easier to quickly get a monitor send from the mixer, making it more intuitive and practical for most rehearsals and small gigs.

Single-Transmitter Four-Receiver Multi-User Monitoring Setup

One U4T transmitter paired with four U4R receivers can distribute the same monitor signal to four users at the same time.
Especially suitable for band rehearsals, worship teams, campus performances, and studio tracking scenarios that require multiple people to monitor simultaneously.

Beltpack Receiver and Large Knob Operation

The receiver uses a compact beltpack design and can be clipped to a belt, waistband, or clothing edge without getting in the way during performance.
The large knurled volume knob makes it easy to adjust volume quickly without looking down, which is especially practical for performers on stage.

Rechargeable Lithium-Ion Battery and Mobile Application Efficiency

Both transmitter and receiver include built-in rechargeable lithium-ion batteries, providing about 5 hours of continuous use per charge.
For regular performances, rehearsals, soundchecks, and recording tracking, it balances battery life, portability, and repeated-use convenience.
