IMPORTANT SAFETY INSTRUCTIONS PLEASE READ THESE INSTRUCTIONS IN A SAFE PLACE WARNING: BEFORE USING YOUR XVIVE U4 MICROPHONE WIRELESS SYSTEM, CAREFULLY READ THE OPERATING INSTRUCTIONS. 1. Observe all instructions carefully in the U4 set manual. 2. Do not to perform service operations beyond those described in the U4 set manual.
WARNING U4 SET PRODUCT INTRODUCTION LISTENING TO AUDIO AT EXCESSIVE VOLUMES CAN CAUSE PERMANENT HEARING DAMAGE. USE AS LOW A VOLUME AS POSSIBLE. Over exposure to excessive sound levels can damage your ears resulting in permanent noise-induced hearing loss. Do not use earphones for a long time and set the volume below 70% or lower.

QUICK START BATTERIES AND CHARGING U4 provides USB charging cable，you can connect to USB Charger Adapter or other USB charging devices Note: Turn off the power switch while charging. Please do not use U4 when charging, which may reduce battery life. OFF ON POWER ON POWER ON Connect to the socket * Always store U4 at room temperature * When storing the unit, please check the battery state regularly and charge if necessary.
CHANNEL SWITCH PAIR TRANSMITTER AND RECEIVER 3 5 2 6 1 4 U4 has six channels. Use the channel switch button to switch the channel. Set the Receiver channel same with Transmitter. The blue Led signal on the receiver will always be on when the connection is successful. CHANNEL SWITCH SINGLE TRANSMITTER AND MULTIPLE RECEIVERS If you want to add more receiver, just set the receivers to the same channel as the transmitter. MAX.
QUICK START VOLUME ADJUSTING LISTENING TO AUDIO AT EXCESSIVE VOLUMES CAN CAUSE PERMANENT HEARING DAMAGE. USE AS LOW A VOLUME AS POSSIBLE. ADJUST TRANSMITTER LEVELS Adjusting Gain and Listening Volume For the best audio quality, start by adjusting the levels from the mixer or audio source and maximizes the signal-to-noise ratio. VOLUME SWITCH <70% Please do not adjust the volume to more than 70%. 09 Line (+4 dBu) Use with mixers or other professional audio devices that send line-level signals.
OPERATION CREATING MONITOR WITH AUX 1. Transmitter connect Mixer Aux send 2. Trun on the Receiver, adjust the volume of the Receiver, and gradually increase from small to large to reach the appropriate volume state 3. Adjust mixer each Aux channel output levels， mixer and send the signal to Transmitter。 Note: The channel faders on most mixers do not affect the volume of the Aux sends.
OPERATION MIAN OUTPUT CREATING MONITOR WITH XLR 1. Transmitter connect Mixer output or other XLR output 2.
OPERATION CHANNEL 1 MULTIPLE TRANSMITTER AND MULTIPLE RECEIVERS When performers have different monitoring needs, they can set up multiple transmitters. If the receiver is set to the channel corresponding to the transmitter, the audio can be received. Or creat mute rehearsal system.
2.4 GHz SPECTRUM OVERVIEW AND INTERFERENCE U4 operates within the 2.4GHz ISM band which is utilized by Wi-Fi, Bluetooth, and other wireless devices. 2.4GHz is an open band and, as such, does not require a license to be used worldwide. Tips and Methods to Improve Wireless System Performance 1) Keep more than 3 meteres distance between Receiver unit and other WiFi transmitters such as routers. 2) Change channels to avoid interference with other WiFi products.
TROUBLESHOOTING ISSUE No Sound SOLUTION • Check that the U4 Receiver's RF LED is lit. • Check whether the device has a signal sent to the transmitter • Check that the power switch is turned on for both the Transmitter and the Receiver. • Ensure that the U4 Transmitter and Receiver are on the same channel.
