XVive U45 Предајник ISM 5,8 GHz

Wireless In-Ear Monitor System Built for Cable-Free Stages

The Xvive U45 wireless in-ear monitor system runs on the 5.8 GHz ISM band, a less crowded slice of spectrum than 2.4 GHz, so it sidesteps most Wi-Fi and Bluetooth interference in busy venues. A plug-on XLR transmitter pairs with a belt-clip receiver to stream a personal monitor mix from any mixer aux, audio interface, or stage snake return. AutoScan automatically picks the cleanest of six channels, so setup takes seconds rather than minutes. This system is engineered for singers, instrumentalists, and presenters who need dependable, full-range audio without the bulk of floor wedges.

What Sets the U45 Apart in the Wireless IEM Category

True-diversity reception uses two antennas inside the receiver to compare signals continuously and switch to the stronger one, eliminating dropouts when the performer moves around the stage. A knurled volume knob on the receiver is large enough to adjust by feel mid-performance, and the included dual USB-C cable charges both transmitter and receiver from a single USB port.

Wireless Performance — 5.8 GHz Band and Range

The 5.8 GHz band gives this system a cleaner RF environment than the saturated 2.4 GHz range used by many budget wireless units, and six switchable channels allow multiple complete setups to operate side by side.

• Wireless Type: 5.8 GHz ISM worldwide open band — usable anywhere without regional restrictions
• Operating Range: 30.5 m / 100 ft line-of-sight — covers small clubs and mid-size stages
• Switchable Channels: 6 — run multiple systems in one space

Audio Quality — Resolution, Latency, and Dynamic Range

Audio resolution matches studio converters, and sub-5 ms latency keeps the in-ear mix tight enough for live tracking and overdubs. A wide dynamic range preserves both quiet vocal details and loud drum hits without compression artifacts.

• Bit Depth / Sample Rate: 24-bit / 48 kHz — better-than-CD audio fidelity
• Frequency Response: 20 Hz – 20 kHz (-3 dB) — full-range monitoring across bass, mids, and treble
• Signal-to-Noise Ratio: 110 dB — clean signal floor with minimal hiss at high volumes
• Total Harmonic Distortion: 0.2% — low coloration of the source mix
• Latency: 5 ms — tight enough for live performance and recording

Hardware and Battery — Transmitter, Receiver, and Power

The transmitter accepts a balanced XLR input or mono unbalanced 1/4" TS via the included adapter, and the receiver's 3.5 mm headphone jack works with any IEMs or over-ear headphones.

• Transmitter Input: XLR or 1/4" TS (adapter included) — connects to any line-level source
• Receiver Output: 3.5 mm / 1/8" headphone jack — works with any IEMs or headphones
• Battery Life: 5 hours — covers a typical gig or rehearsal set
• Charging Time: 2.5 hours (full charge) — quick turnaround between shows
• Use While Charging: Yes — no downtime on long event days
