The internal battery in both the transmitter and the receiver lasts for 5 hours. The battery is easily charged using the included 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.
If you have more than one U4 receiver, you can broadcast a signal to a whole group of people. This can be useful in situations where one person needs to communicate clearly and directly to a group—either in noisy environments or in situations where you don’t want to disturb others. This makes it an excellent option for things like group demos, presentations or tours.
FREE AND EASY RECORDING
For recording musicians, whether in a home or professional studio, going wireless makes the whole process so much freer and easier—especially if you’re playing or singing AND engineering at the same time!
If you want to practice guitar or bass privately—for example late at night—you can run your signal through a multi-effect unit or modeling amp, send either the ¼” or XLR output to your headphones or earphones, and move freely around your home!
