ln order to
prevent
overloading
of the expensive bass system
in
the speaker boxes
from
high-amplitude distortions
at low
fre-
quencies,
a SUBSONIC
filter
[9]
can
be
cut in. Such extremely
low frequencies
(rumble)
are
mainly
produced
by turntables.
However, the subsonic
filter can
be
programmed
for any source
(refer
to
Section
3.3.2)
