What to do
• Orient the microphone so that it is not pointing directly at its respective
loudspeaker.
• Try a different microphone.
• Try a different position for the L1 system and/or vocalist on stage.
• Increase the distance from the L1 system to the microphone.
• Reduce the HIGH frequencies by adjusting the zEQ on the microphone
channel.
• Try notching out a particular frequency that could be causing the
feedback by adjusting the Para EQ on the microphone channel.
• Temporarily bypass any audio effects used (Mod, Delay, Reverb) to see if
they might be contributing to the feed-back problem.
• Check if the Aux output is configured for the desired tap point for each
input channel. Refer to "Routing Input Signals to the Aux Output" on
page 21.
• Verify that each input assigns the desired signal level to the Aux output.
• Check that the USB cable is properly connected to the mixer and
computer.
• Try a different USB cable.
• Make sure the mixer is turned on.
• Verify that the desired mixer input channels are assigned to the left and
right USB output channels. See "USB to PC" in the Prefs menu.
• Make sure that the Trim level of the respective input channel is turned up
enough so that the green LED is on, indicating that there is a strong input
signal.
• Check the Input and Output level meters under the Prefs menu to confirm
that there is a signal at both the input and output stages.
• Verify that your computer USB input is working by connecting another
USB-compatible audio device.
• If you are using recording software on a computer, check the software
requirements. You may need to configure the software settings for
48 kHz/24-bit operation.
• To determine if there is an issue with your flash drive, connect a different
brand flash drive
