Dynamic Noise Limiter - DNL
The
DNL
suppresses
tape
noise
without
greatly
affecting
the
naturalness
of
the
music
signal.
It
operates
only
during
quiet
passages
and
in
the
absence
of
signal
on
the
tape,
which
is
when
noise
is
most
apparent.
The
DNL
operates
during
play-
back
and
during
tape-monitoring.
Thus
recordings
being
made
on
this
recorder
are
entirely
unaffected
by
the
DNL.
The
DNL
is
operated
by
