Xvive Audio U45 Overview

Providing superior interference-free transmission over more traditional devices in the crowded 2.4 GHz range, the U45R4 from Xvive Audio is a 5.8 GHz wireless IEM system with one transmitter and four receivers. Perfect for transmitting wireless signals from mixers or the line outputs of amps, the U45R4 provides crisp, 24-bit / 48 kHz audio for IEMs and headphones.

With this system configuration, the four included receivers are designed to operate on the same frequency, allowing and entire ensemble of up to four performers to receive the same signal for their IEMs at the same time, making this an ideal choice for a whole-band IEM solution. This wireless system sports six wireless channels and up to a 100' wireless range, depending on obstructions and absorption. Up to six systems can be used in a single area. The U45R4 provides low-latency performance of less than 5 ms. The transmitter and receivers feature convenient and fast USB-C charging, and the internal battery in each device provides up to five hours of operation on a single charge.

Auto-Scan for Best Channel
Press and hold the channel button on the receiver for three seconds to enter Channel Scan mode. The receiver’s channel LED will flash during scanning and then will stay on the optimal wireless channel. When scanning is complete, manually set the transmitter’s channel to be the same as the receiver's channel.
Adjustable Transmitter Levels
For the best audio quality, you can adjust the transmitter input level with the dedicated switch. When set to Line, the U45T will output audio at the standard line level of +4 dBu, ideal for professional audio devices like mixers. When connecting a consumer audio device, such as a portable audio player or computer, you can switch it to Aux and the U45T will transmit audio at -10 dBV.
Adjustable Volume
The handy volume switch on the receiver's front panel lets you easily adjust volume to meet your performance needs. The built-in 3.5mm dual-mono output is compatible with a wide array of headphones and IEMs, maintaining a smooth frequency response with most listening devices.
