U3C Phantom Power Connections

2.4 GHz SPECTRUM OVERVIEW AND INTERFERENCE

U3C 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.
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 1~4 channels, U2 and U3/U3C use in sametime max is 6 sets.

TROUBLESHOOTING

microphone is turned on and receiving signal from the U3C Transmitter. • Check that the power switch is turned on for both the Transmitter and the Receiver. • Ensure that the U3C Transmitter and Receiver are on the same channel. • U3C will provide 12V or 48V phantom power to condenser microphone. Please select your microphone phantom power volts. • If used in dynamic microphone, the current consumption will be the same as that of a condenser microphone. • The receiver can be paired with one Transmitter at a time.
Distortion or Faint Sound| • If you connect the device with a receiver, check if the device is balanced XLR interface
Signal instability: RF LED

flickering or off completely

| • See, “Tips and methods to improve wireless system performance” page 12
Unable to switch the channel| • The channel switch locks after 15 seconds. Double-click the channel button to unlock and reset.
Multiple connect| Use one transmitter can connect with more than 2 receivers.
Phantom Power| Never plug single-ended (unbalanced) or dynamic microphones into U3C,
can be permanently damaged if phantom power is applied to them.
