About the
Dolby
noise-reduction
system
The Dolby
noise-reduction
system
is
designed
to effectively
reduce
the
annoying
high-frequency
"hissing"
noise
which
can occur
with
cassette
topes. During
recording,
the
system functions
to
increase
the
high-frequency
sound
level,
and then, during
playback,
that
same
portion
is
weakened
to bring
it
back to the
previous
level.
This unit
includes
two
types
of Dolby
noise-reduction
systems, the
Dolby
B NK-type
and
C NR-type.
Dolby
B-type
noise-reduction
Noise is
reduced
to
about
one-third.
Use this
system when
playing
back
tapes
recorded
by the
Dolby-B
noise-reduction
system,
such as
prerecorded
music
tapes,
etc.
Dolby
C-type
noise-reduction
Noise is
reduced
to about
one-tenth.
Use this
system
for the
recording
and
playback
of
sound
sources
that
have
a wide
dynamic
range
and
good tone
quality,
such
as FM
broadcasts
of live
performances,
etc.,
and for
playing
back
such
tapes.

of the
sound
source's
high-frequency
