Possible solution
Turn off the power, wait until the amplifier cools down, and then
turn on again.
Connect the cable all the way in so that it is firmly in place.
Wait until the amplifier cools down. If the unit won't automatically
reset itself, turn off the power, and then on again.
Aim the speaker away from the area where the microphone
picks up sound.
Lower the volume of input device and locate the microphone
more closely to the sound source.
Set the [HPF] switch and [D-CONTOUR] switch of each speaker
to the same positions.
When the [MIC/LINE] switch is set to [MIC], and even if you
lower the volume fully the sound is still distorted, set the switch
to the [LINE] position. If the sound is still distorted even if the
switch has been set to [LINE], lower the volume of the con-
nected input devices.
Turn the [LEVEL] knob to lower the output level to a point so that
the [LIMIT] indicator lights only occasionally.
Set the [MIC/LINE] switch to the [MIC] position.
Lower the input level or the output level until the [LIMIT] indica-
tor lights occasionally.
