Pioneer DV-210K-K Operating Instructions Manual page 23

Note
• You can adjust the high tone in a range of
five steps and the low tone in a range of
five steps.
• If the microphone level is too high, the
sound may distort. In this case, lower the
volume.
When "howling" occurs
If sound from the speakers is picked up by a
mic and output again through the speakers,
the result is a screeching sound known as
"howling".
To eliminate howling:
• Point the mic away from the speakers.
• Move the mic away from the speakers.
• Turn VOLUME counterclockwise to lower
the volume level.
• Press the KARAOKE button on the remote
control, then within 5 seconds press the
 (ECHO –) button to reduce the echo.
Note
• Reduce the volume when plugging in the
microphone to prevent feedback.
