latency. This wireless system operates on the 2.4 GHz ISM
band for crystal-clear transmission and excellent signal
integrity on stage and it covers a range of 70 feet without
any signal dropouts. The lithium-ion batteries help make
the U2 wireless system environmentally friendly and they
last up to 5 hours on a full charge. The housing is made of
durable ABS plastic that can withstand the rigors of
touring and the harshest environments. Thanks to its
simple and compact design, this wireless system is easily
integrated in any pedalboard conguration. Go wireless
with the Xvive U2 system. It will clean up the stage and
give you freedom to move.

Tips and Methods to improve the performance of the
wireless system
1) Keep more than 3 meters distance between the U2
receiver and other transmitters such as WiFi routers.
2) Change channels to avoid interference with other
WiFi systems.
3) In case of interference from other WiFi systems, shorten
the distance between the U2 receiver and transmitter.
2.4 Ghz Frequency Tables
The U2 operates in the 2.4 GHz ISM band, the same band
used by Wi-Fi, Bluetooth, and other wireless systems.
2.4 GHz is an open band and as such does not require a
license to operate worldwide.
2.4 GHz WIRELESS OVERVIEW AND INTERFERENCE
CHANNEL 1 2402 MHz, 2480 MHz, 2482 MHz
CHANNEL 2 2408 MHz, 2472 MHz, 2474 MHz
CHANNEL 3 2420 MHz, 2456 MHz, 2458 MHz
CHANNEL 4 2432 MHz, 2448 MHz, 2450 MHz
U2 channels 1-4 use the same frequencies as U3/U3C/U4
channels 1-4. A maximum of six U2/U3/U3C and U4 sets
can be used at the same time.

14
Four channels
The U2 wireless guitar system has four dierent
channels and up to four pairs of systems can be used
simultaneously. If you have guitar, bass, keyboard and other
instruments in your band, multiple U2 systems can be set up
for dierent channels to prevent signal interference. If there
is only one player, the channel selection can also be used to
prevent interference from routers or other WIFI devices
working on similar frequency bands. We generally
recommend using channel 1.
Portable plug-and-play design
The U2 wireless system uses a portable plug-and-play
design for both the receiver and the transmitter. This is very
convenient for quick switching between guitars or basses
and also between dierent ampliers, eect pedals or other
audio equipment and allows you more exibility in setting
up your equipment.
Q & A
One transmitter and multiple receivers
You can use one transmitter with multiple receivers.
For example, if you want to connect a guitar to two
ampliers, or to an eects pedal and a pedal tuner, you can
simply use multiple receivers set to the same channel.
U2 receiver
Because U2 is a 2.4 GHz wireless system, please avoid placing
the receiver near other signal-emitting devices. It is
recommended that your U2 receiver be kept at least 3 meters
away from other 2.4 GHz transmitters and WIFI routers.
Channel switching and locking
The channel selection function is unlocked for seconds after
starting the device. You can click the "Channel" button to
select the desired channel. The blue LED will blink after
clicking. Flashing once means you are in channel 1. Flashing
twice means you are in channel 2, and so on. The channel
select function will be locked after 15 seconds. Double-click-
ing the Channel button will unlock the function again.

15
Charging
A "Y" shaped cable is included in the package. You can use it
to charge the transmitter and the receiver at the same time.
The required output voltage is 5 V. The red LED light of the
U2 is always on for normal use. When the red LED light
ashes, the battery is low and must be recharged
immediately. The red LED on the transmitter and receiver
will ash during the charging process and will automatically
turn o when the battery is fully charged.
Blue LED ashing
A ashing blue LED indicates signal interference. Please
switch to another channel. Turn other o other 2.4 GHz
devices (e.g. WIFI routers) or keep your distance from them.
Make sure the U2 transmitter and receiver antennas are
within signal range.
Antenna Angle
The antenna is built into the rear end of the U2. Its angle can be
changed by about 180°. The strongest signal will be emitted /
received on the front part of the transmitter / receiver.
Please try to keep the front parts facing each while you play.
Do not block the antenna with your hand or other objects,
and keep the devices within signal range. If you encounter
interference from other devices or need more distance, you
can change the angle of the antenna and adjust it to the
best condition.
Supported pickups and musical instrument
The U2 wireless system works well with passive electric
guitar pickups and with piezo electric pickups for acoustic
guitars or violins. For the active electric guitars, the pickup
output voltage must be less than 5.6 Vp-p. Please keep the
U2 transmitter away from the microphone in acoustic guitars
with microphone pickup system. The transmitter works best
when connected directly to the instrument. Please avoid
connecting it to distortion eect pedals or any other high
power outputs, as this may cause sound distortion.
USB connector
The USB port is only intended for battery charging and
does not support rmware upgrades.
