27 SUBSONIC FILTER Switch
Superlow-frequency
noise,
caused
by
warped
or
off-centered
records,
forces
the
moving
structure
of
a
woofer
to
work
excessively;
such
abnormal
excursion
generates
distortion.
This
filter
cuts
such
superlow-frequency
noise
below
16Hz
and
im-
proves
bass
response.
28 HIGH FILTER Switch
Set
this
switch
to
the
ON

noise
of

the

is
