Use a pair dynamic microphones at the same time or send audio to active speakers with the Xvive U3D digital wireless audio system. Operating in the 2.4 GHz wireless band, with a 20 Hz to 20 kHz frequency response and less than 5 ms latency, the U3D can be used by presenters, performers, and DJs for a wide variety of applications.

The system offers a 90' range, and includes four rechargeable batteries with a five-hour life for both the two receiver and two transmitter units. For presentations and performances, plug your favorite dynamic XLR mics into the transmitters and send the mic signals to a mixer, PA, or recording device. Alternatively, plug the transmitters in the XLR outputs of a mixer or recording device and send your mix wireless to the receivers plugged into powered monitor speakers or a portable PA system. The U3D can operate with six systems simultaneously, and is suitable for live vocals, presentations, DJ gigs, video productions, and houses of worship.

The System The system is comprised of a transmitter unit, which connects to your microphone; and a receiver, which connects to a mixer, sound interface, preamp, XLR cable, or snake.
Your True Voice The U3 system features high-resolution, 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. Sing or speak without compromising the quality of your voice or your microphone.
Hold On to Power 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.
Free Your Voice The U3 system is not only great for singers and rappers. Wireless freedom is liberating for harmonica players, public speakers, DJs, preachers, auctioneers, actors, politicians, and anyone who wants to move freely while speaking or performing to an audience.
Bypass the Mixer If you need to address a crowd through powered speaker cabinets, not only you do not need a cable, you don't need a mixer. Just connect your U3 receiver directly to the XLR input of the cabinet.
Control Your Range The U3 receiver can be connected to an XLR cable or snake, meaning that the transmitter's signal doesn't have to reach all the way to the soundboard or monitor desk; it can broadcast to the front of the stage, or any central and convenient location.
Get Amped Beyond all the vocal applications, the U3 system can also be used with microphones for guitar amplifiers as well as direct audio signals from balanced XLR outputs, for example from multi-effect processors or keyboards.
PA Friend Run wirelessly from a PA mixing console to a powered main speaker, avoiding the hassles and risks of running speaker cables across a crowded venue. You can also run wirelessly between powered mains or between powered monitors.
