2.4 GHz SPECTRUM OVERVIEW AND INTERFERENCE

U2 operates within the 2.4GHz ISM band which is utilize 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 U2 Receiver unit and other WiFi transmitters such as routers.
2. Change channels to avoid interference with other WiFi products.
3. In case of environmental interference from other WiFi systems, shorten the distance between the U2 receiver and transmitter units.

2.4Ghz Frequency Tables

Q & A

Four channels

The U2 wireless guitar system has four different channels, and can use up to 4 pair of systems at the same time. When your band plays for guitar, bass, keyboard and other instruments, U2 can set up different channels for them to prevent signal interference. When there is only one player, the different channel function can also be used for him/her to prevent interferences from different frequency bands of routers or other WIFI devices. Generally we recommend to use Channel 1

Portable Plug-and- Play design

U2 wireless system uses a portable design; both the receiver and the receiver are plug-and-play design. It is very convenient for fast switching among guitar, bass, amplifiers, effect pedal and other audio equipments. It provides more flexibility in adjusting the equipments.

One Transmitter and multiple Receivers

When using a transmitter, you can use multiple receivers. For example, if you want to connect a guitar to two amplifiers or connect to effect pedal and pedal tuner, you need just use multiple receivers with setting up to be the same channel.

U2 Receiver

Since U2 is the 2.4 GHz wireless system, please avoid putting the receiver close to other signal emitting devices. It is recommended that your U2 receiver keep a distance of more than 3 meters from the other 2.4 GHz transmitter and WIFI router.

Channel switching and locking

The select function of channel is unlocked within 15 seconds after the product is started. You can click the "Channel" button for selecting the channel that you want. After the click, the blue LED will flash. Flash once means you are in Channel 1. Flash twice means you are in Channel 2, and so forth. The select function of channel will be locked after 15 seconds. Double clicks for the Channel button can activate the function again.

Power charge

There is a "Y" shape cable in the package. It can charge the transmitter and receiver at the same time. The voltage output is 5V. The red LED light of U2 will be always on for normal use. Red LED light flashing means low battery which requires immediate power charge. During power charging, the red LED on the transmitter and receiver will light on and they will be light off automatically after full power charge.

Blue LED Flashing

The blue LED light flashing indicates there is signal interference. Please switch to another channel, turn off or stay away from other 2.4GHZ WIFI, to make sure the U2 transmitter and receiver antennae be in the signal receiving range.

Antennae angle
The rear end of U2 is the antenna, which can be used at about an angel of 180°. The front signal of the transmitter and the receiver is the strongest. Please try to keep the front to face each other during using. Do not block the antenna with your hand or other items, and keep the signal within the receiving range of the antenna. When confront with interferrence from other devices or need more distance for using, you can change the antenna's angle and adjust it to be the best condition.

Supportive pickup and musical instrument
U2 wireless system works fine with passive electric guitar pickup, Piezo-electric acoustic guitar pickup and Piezo-electric violin pickup. For the Active electric guitar, pickup output voltage need less than 5.6Vp-p. Acoustic guitar with microphone pickup system, Please keep the U2 transmitter away from the microphone. Transmitter is better to connect to the instrument. Please avoid connecting it to distortion effect pedal or high power output interface which may incur the timbre distortion.

USB port
USB only works for charging function, does not support firmware upgrade.
