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.

OPERATION

CREATING MONITOR WITH AUX

1. Transmitter connect Mixer Aux send.
2. Turn 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.

CREATING MONITOR WITH XLR

1. Transmitter connect Mixer output or other XLR output.
2. Turn 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 channel faders output levels mixer and send the signal to Transmitter.

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 create 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 meters distance between 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 receiver and transmitter units.

2.4Ghz Frequency Tables

* U2 1~4 channels are the same as U3/U3C/U4 1~4 channels, U2, U3/U3C and U4 use in same time max is 6 sets.
