QUICK START

MICROPHONE APPLICATIONS

1. Plug your XLR dynamic microphone or battery-powered condenser microphone into the U3 Transmitter.
   
2. Plug the Receiver into the desired XLR channel input of your Mixer.
   
3. Turn on the Transmitter and the Receiver and check that they are both set to the same channel.
   
4. After connecting successfully, the LED lights on the Receiver will stay on.
   
5. Check the connection by talking through the microphone.
   

MONO CONNECTION TO A POWERED SPEAKER

1. Connect the Transmitter to a Main or Aux XLR output of the mixer or other audio source.
   
2. Connect the Receiver to the XLR input of a powered PA loudspeaker or monitor.
   
3. Set the Receiver to the same channel as the Transmitter. The Transmitter can be paired with two or more receivers, as long as they are all set to the same channel.
   

TWO U3 SETS FOR STEREO / DUAL MONO PA APPLICATIONS

For stereo PA/DJ systems, connect Transmitter #1 to the left main XLR output of the mixer, and connect Receiver #1 to the XLR input of the left main loudspeaker. When you power them on, set them both to the same channel. Then, connect Transmitter #2 to the right main XLR output of the mixer, and connect Receiver #2 to the XLR input of the right main loudspeaker. When you power them on, set them both to the same channel, which must be a different channel than set #1.

For mono PA/DJ systems, connect Transmitter #1 to the mono main XLR output of the mixer, and connect Receiver #1 to the XLR input of one of the main loudspeakers. When you power them on, set them both to the same channel. Then, connect Receiver #2 to the XLR input of the second main loudspeaker. When you power it on, set it to the same channel as set #1. Both speakers will receive the same mono signal.

BATTERIES AND CHARGING

Connect to U3 units

Connect to 5V USB power

Note:
Turn off the power switch while charging.
Please do not use U3 when charging, as this may reduce battery life.

*Always store U3 transmitter and receiver at room temperature.
*When storing the units unused for longer periods, please check the battery state regularly and charge if necessary.

2.4 GHz WIRELESS OVERVIEW AND INTERFERENCE

U3 operates on the 2.4 GHz ISM band, which is also used by Wi-Fi, Bluetooth, and other wireless devices. 2.4 GHz 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 metres of distance between the U3 receiver unit and Wi-Fi transmitters, such as routers.
2. If you experience interference from Wi-Fi devices in the vicinity, try changing to a different channel on the U3 transmitter and receiver.
3. If necessary, shorten the distance between the transmitter and receiver units.

2.4 GHz Frequency Tables

* Channels 1-4 of the Xvive U2 Guitar Wireless System occupy the same frequencies as channels 1-4 on the U3 Microphone Wireless System and U3C Condenser Microphone Wireless System.
Combined maximum number of U2/U3/U3C sets that can be used simultaneously in one location is six.
