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. 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!
