The XVIVE U45 stands out from traditional wireless systems as it operates in the globally open 5.8 GHz ISM band. This choice offers superior sound quality without the interference often encountered in the crowded 2.4 GHz range (where most routers operate). With 24-bit / 48 kHz sound quality and an impressive dynamic range of 110 dB, the system delivers the signal from the console to your ears with absolute precision. The 20 Hz – 20 kHz frequency response guarantees that you will enjoy full bass and clear treble in every performance.

For a performer on stage, response time is everything. The XVIVE U45 offers latency of just 5 ms, a value so low that it is practically imperceptible to the human ear. This means that the sound reaches your In-Ear monitors in real time, allowing you to stay perfectly synchronized with the rhythm and the other musicians. Whether it's an intense live performance or a studio rehearsal, the signal stability and harmonic distortion of just 0.2% ensure that your listening remains true to the source, without any alterations.

The system features 6 interchangeable channels, allowing up to 6 different systems to operate simultaneously in the same space without interfering with each other. The operating range reaches up to 30.5 meters (100 feet) in a straight line, offering great freedom of movement even on the largest stages. The U45T transmitter is equipped with an XLR socket, and a 1/4" TS adapter is also included for connection to amplifier line outputs or mixers. This flexibility makes the U45 a versatile tool that adapts to all kinds of equipment and professional setups.

Xvive Audio placed special emphasis on the dimensions and weight of the device. The transmitter weighs only 90 g and the receiver 118 g, making them extremely lightweight so as not to bother the performer. The U45R receiver features a 3.5 mm (1/8") headphone output, compatible with all professional In-Ear monitors on the market. Its compact design (just 2.36" x 1.85" x 1.61" for the receiver) allows for easy placement on the belt or pocket, while the discreet black finish goes unnoticed under stage lights.

The U45 system is powered by internal rechargeable Lithium-Ion batteries, which offer up to 5 hours of continuous operation on a single charge. The charging process is extremely simple via any 5V USB port and requires only 2.5 hours for a full charge. One of the most important advantages is the ability to use while charging, ensuring you will never be without sound if you forget to charge the device before the performance. The durable battery construction guarantees hundreds of charging cycles without significant capacity loss.

The XVIVE U45 comes as a complete package that includes the transmitter U45T, the receiver U45R, and the necessary adapter for 1/4" (Jack) connection. It is designed to be Plug-and-Play, allowing you to connect and start your performance within seconds. With a signal-to-noise ratio (SNR) of 110 dB, the system offers quiet operation without the annoying 'hiss' found in cheaper wireless systems. It is the ideal upgrade for any musician who wants to get rid of cables and move into the digital era of 5.8 GHz wireless listening.
