Xvive U45DR4 Stereo Wireless In-Ear Monitor System - 5.8GHz Black

Put an entire group on the same wireless stereo monitor mix without filling the stage with separate transmitters. The Xvive U45DR4 stereo in-ear wireless monitoring system combines one U45D transmitter with four independent receivers, giving bands, ensembles, houses of worship and production teams a streamlined monitoring solution for up to four performers. The 5.8GHz digital wireless platform delivers 24-bit/41.6kHz audio with less than 5ms latency, a 20Hz–20kHz frequency response and 110dB dynamic range. All four receivers listen to the same transmitted stereo feed while retaining individual headphone volume and monitoring-mode control, making the system easy to adapt to each performer.

Four Receivers Share One True Stereo Monitor Feed

Setup is straightforward: select one of six wireless channels on the transmitter and set all four receivers to the same channel. Each performer then receives the stereo feed independently and can choose between Stereo, Left, Right and Mix monitoring modes to determine how the incoming channels are routed to their IEMs or headphones. Each receiver's 3.5mm dual-mono headphone output supports impedances from 6–600 ohms, accommodating a wide variety of professional in-ear monitors, earphones and headphones.

5.8GHz Wireless Supports Responsive Multi-System Monitoring

With less than 5ms latency, the U45DR4 keeps vocals, instruments and backing tracks closely aligned with live performance while giving musicians up to 100' of wireless operating range depending on RF conditions. For productions requiring more than one monitor mix, as many as six U45D systems can operate simultaneously, with each transmitter assigned to one of the six available channels. A 110dB signal-to-noise ratio complements the system's 24-bit digital audio for clean monitoring across rehearsals, performances and mobile production environments.

Flexible Mixer Connections and Rechargeable Power Simplify Setup

The transmitter uses balanced XLR stereo inputs and provides selectable Aux (-10dBV) and Line (+4dBu) operating modes for connecting to different output levels from mixing consoles and other audio equipment; appropriate adapters can also accommodate compatible unbalanced 1/4" TS monitor outputs. Rechargeable lithium-ion batteries provide up to five hours of operation for both the transmitter and each receiver, with USB-C charging simplifying turnaround between sessions and shows. Compact housings keep the system easy to integrate into portable rigs, making the Xvive U45DR4 a practical all-in-one package for putting four performers on a shared wireless stereo monitor mix.
