Poor-quality record reproduction
Superlow-frequency noise, caused by warped or off-centered re-
cords, forces the moving structure of a woofer to work excessively;
such abnormal excursion generates distortion. To prevent such
noise, set the SUBSONIC switch to the 16 Hz position.
When you hear hum continuously, check the grounding of your
turntable.
You may hear howling or acoustic feedback, caused when the
pickup of your turntable is affected by the vibrating sound waves
from the speakers, and undesired signals are amplified. To avoid
howling, move the turntable away from the speakers or install the
turntable on a solid, non-resonating stand.
When you hear the irritating noise during record playback, it is’
suggested that you check if there is dust accumulated on the surface
of the record and on stylus tip. The cause may be a worn stylus tip.
When you use a record cleaner, be sure to always use one of high
quality.
