Troubleshooting
Problem What to check
Poor-sounding
playback of a
stereo
recording using
a CD player,
MP3 player or
other such
device. (cont.)
If using the T1 with an L1 model I system:
• Do not use a female 1/8” stereo-to-male ¼” stereo adapter when connecting
a portable device to an input channel on the L1 model I power stand. The L1
model I input channels use a monaural (TS) connection. Use a stereo-to-
monaural adapter.
Microphone is
encountering
feedback. • Orient the microphone so that it is not pointing directly at its respective L1
Cylindrical Radiator loudspeaker.
• Try a different microphone.
• Try a different position for the L1 system and/or the 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 feedback 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 input” on page 26 of the
owner’s guide.
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 properly 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.
Unable to send
audio from a
computer to the
T1 via 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 the computer is playing and that the audio setting is not disabled in
your computer.
