Break free from cables and discover the liberating power of wireless audio monitoring with the U4 system, designed for musicians who demand professional-grade sound quality without compromise. This advanced wireless system delivers exceptional 24-bit/48 kHz audio resolution with a pristine frequency response spanning 20 Hz to 20 kHz, boasting a remarkable 107-decibel signal-to-noise ratio that surpasses CD quality by a significant margin. The built-in battery provides up to 5 hours of continuous operation and charges quickly via the included USB cable in just 1.5 to 2.5 hours.
Perfect for live performance, studio work, or home practice, the U4 system excels in multiple applications from basic monitor mixing to complex multi-user setups. Recording musicians will appreciate the freedom to move around while tracking, particularly when handling both performance and engineering duties simultaneously. Late-night practice sessions become neighbour-friendly when you route your guitar or bass through effects units or modelling amps directly to your wireless headphones.
The system’s versatility shines in group applications, supporting up to six musicians with individual U4 sets for customised monitor mixes per band member. This makes it an ideal solution for studio recording sessions, band rehearsals, and live performances where traditional monitoring might be impractical. Bands can now rehearse in apartments or during late hours without disturbing others, as the wireless system eliminates the need for PA speakers while maintaining professional audio standards.
