The system is comprised of a transmitter unit, which connects to your audio source (typically a mixer or sound interface); and a belt-pack receiver, to which you connect your earphones or headphones.
LOUD AND CLEAR'
The U4 system features high-resolution, 24-bit / 48 kHz audio, with a very wide and smooth frequency response between 20 Hz and 20 kHz, a signal-to-noise ratio of 107 decibels, and more volume than you’ll ever need. The sound is better than CD quality, and much, much better than MP3 quality!
LONG, EASY CHARGE
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.
