The protection system has

operated, shutting down the power

supply.

The cable is not connected

properly.

The LINK MODE switch is set

incorrectly.

The MIC/LINE switch is set to LINE.

The output limiter is active.

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.
