The internal battery in both the transmitter and the receiver lasts for 5 hours. Both units can be easily charged at the same time using the included dual-USB cable and any standard 5V USB charger—and charging takes between 1.5 and 2.5 hours depending on the current of the charger being used.
U2 can be used to replace any ¼” instrument cable. The most common application is to run a guitar or bass, wirelessly, to an amplifier—in a live performance, at home or in the studio. But there’s a lot more you can do with the U2 System!
Especially if you feel most comfortable with your instrument in hand, going wireless at home is truly liberating. Wander from room to room, sit anywhere, stretch your legs… you’re free. When recording at home or in the studio, having less cables means no tangles—and no tonal compromise thanks to the system’s 24-bit audio.
If you have more than one transmitter, you can keep one connected to each guitar; and when switching guitars, just power off the transmitter before you take off the first guitar, then power on the second unit as you strap on the second guitar. Just make sure all units are set to the same channel!
