The system is comprised of a transmitter unit, which connects to your audio source (typically an electric guitar or bass); and a receiver, which is connected to an amplifier, effect pedal/pedalboard, DI box or audio interface.
The U2 system features crystal-clear 24-bit / 48 kHz audio, with a very wide and smooth frequency response between 20 Hz and 20 kHz and a signal-to-noise ratio of 107 decibels. Going wireless with the U2 system will not compromise your precious tone!

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.
