Possible solution
Connect the power cord properly.
Turn off the power, wait until the amplifier cools
down, and then turn on again.
Connect to the INPUT jack properly.
If you are using a single DXR, set the LINK
MODE switch to MONO.
Wait until the amplifier cools down. If the device
won't automatically reset itself, turn off the power,
and then on again.
Keep the speaker away from the area where the
microphone picks up sound.
Lower the volume of the input device and locate
the microphone more closely to the sound
source.
Set the HPF switch on 120Hz or 100Hz if you get
feedback in low frequency bands.
• (DXR series) Set the HPF and D-CONTOUR
switches of each speaker to the same
positions.
• (DXS series) Set the POLARITY switch, the LPF
switch, and D-XSUB switch of each speaker to
the same position.
• Lower the volume of the input device to a point
no higher than where the LIMIT indicator lights
occasionally.
• If sound continues to be distorted even if you
turn down the volume to the minimum, set the
MIC/LINE switch to the LINE position (if the
switch is set to MIC).
Use the LEVEL control to lower the output level to
a point no higher than where the LIMIT indicator
lights occasionally.
Set the MIC/LINE switch to the MIC position.
Lower the input level or the output level to a point
no higher than where the LIMIT indicator lights
occasionally.
