High-quality, ultra-compact wireless system for in-ear monitors Audiophile 24-bit / 48 kHz sound with less than 5 ms of latency Industry standard 2.4 GHz wireless technology Reliable, solid RF connection over a range of 90 feet Can also wirelessly broadcast to an audio recorder or mixer THE SYSTEM 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. APPLICATIONS The basic application is to run a monitor mix from a soundboard, wirelessly, to one set of headphones or in-ear monitors—live, at home or in the studio. But there’s a lot more you can do with the U4 System! DIRECT COMMUNICATION 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! DISCREET PRACTICE 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!
