What to do
• Make sure the power cord is fully engaged into both the F1 Model 812 Loudspeaker and the AC
outlet.

same AC outlet.
• Try a different power cord.
• Make sure the VOLUME control is turned up.
• Make sure volume control is turned up on your instrument.
• Make sure your instrument or audio source is plugged into the appropriate input connector.
• If the F1 Model 812 Loudspeaker is receiving input from the F1 Subwoofer, make sure the
subwoofer is turned on.
• Lower the volume of the connected audio source.
• If you are connected to an external mixing console, make sure input gain to the mixing console
input channel is not clipping.
• Reduce the output of the mixing console.
• Reduce the input gain on the mixing console.
• Try positioning the microphone so it nearly touches your lips.
• Try a different microphone.
• Use the tone controls on the mixing console to reduce the offending frequencies.
• Increase the distance from the loudspeaker to the microphone.
• If using a vocal effects processor, make sure it is not contributing to the feedback.
• If using the F1 Model 812 Loudspeaker without the F1 Subwoofer, make sure the EQ switch is
set to FULL RANGE.
• If using the F1 Model 812 Loudspeaker with the F1 Subwoofer, check to see if the POLARITY
switch is in NORMAL mode. If there is a fair amount distance between the F1 Subwoofer and
the F1 Model 812 Loudspeaker, setting the POLARITY switch to REV may improve bass.
• If using two F1 Subwoofers, make sure that the POLARITY switch is in the same position on
each subwoofer.
