Xvive U3 Wireless XLR System

Turn any dynamic microphone into a wireless workhorse with the Xvive U3 Wireless XLR System. Built for real-world stage and studio use, this compact 2.4 GHz digital wireless solution delivers crystal-clear audio, ultra-low latency, and reliable performance across a range of demanding situations—from live vocals to video productions and house-of-worship environments.

Why the Xvive U3 stands out

Designed to keep you untethered without sacrificing sound quality or reliability, the U3 system blends professional specs with everyday practicality. Enjoy a near-instant connection with latency under 5 ms, ensuring your lips and mic are perfectly in sync with the performance or presentation. The 2.4 GHz bandwidth (2400 to 2483.5 MHz) provides stable transmission with up to 27 meters of real-world range, so you can move freely on stage or around a crowded set.

• Six simultaneous channels so multiple wireless mics can operate in the same venue without interference.
• High-resolution audio at 24-bit/48 kHz with a dynamic range of 110 dB and SNR of 110 dB for clear, quiet quieting of stage noise.
• Low noise, strong RF performance with -88 dBm RF sensitivity and 10 mW E.I.R.P. maximum output for dependable coverage in typical live environments.
• Dynamic mic-friendly transmitter designed for plugging directly into a dynamic microphone or into DI/auxiliary XLR output gear; receiver freely connects to a live sound mixer, portable PA, or recorder.
• Minimal setup friction with simple XLR-to-XLR path and USB connections on both transmitter and receiver for power and charging.

Smart, practical design for real-world use

The U3 system uses a compact, rugged form factor with a fixed antenna design to keep things simple and reliable on crowded stages. Each unit houses a rechargeable Li-ion battery (3.7 V, 860 mA) offering up to ~5 hours of operation per unit, and both transmitter and receiver feature USB ports for easy recharging between gigs. The built-in, non-removable 1/4 wave sleeve dipole antennas ensure steady RF performance without worrying about antenna misplacement during fast-paced setups.

How it works in practice

Attach the transmitter to a dynamic mic or DI output, then plug the receiver into your mixer, PA system, or audio recorder. The system broadcasts across six channels, allowing you to run multiple wireless mics simultaneously in the same space. With a generous input/output range and flexible gain options, you can dial in the exact microphone level you need—Mic mode for dynamic mics at up to 2.8 V p-p, or Line mode for line-level sources up to 7 V p-p with appropriate gain adjustments.

• Transmitter: XLR male input for mic or DI connection; USB port for power and charging; compact footprint (3.1 x 2.9 x 9.8 cm; 93 g).
• Receiver: XLR female output to mixer/recorder; USB port for power and charging; compact footprint (3.1 x 2.9 x 9.8 cm; 92 g).

Ideal use cases

Whether you’re tracking a live performance, delivering a keynote, shooting a run-and-gun video, or running a church service, the U3 offers reliable wireless performance with minimal setup time. It’s especially well-suited for:

• Live vocal performances and stage productions
• Corporate presentations and event hosting
• Video production where mobility and clean audio are essential
• Houses of worship needing dependable wireless mic coverage
