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)
