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.
Aux output does not sound
right.
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 26.
Note: No reverb comes from the Aux output even if the tap point is Pre or Post.
Verify that each input assigns the desired signal level to the Aux output.
Unable to send T1 audio to
a computer through a USB
connection.
Check that the USB cable is properly connected to the audio engine and computer.
Try a different USB cable.
Make sure the audio engine is turned on.
Verify that the desired audio engine 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 48kHz/24-bit operation.
