Corporation.
7. DOLBY B-C NR SELECTOR
The
current
Dolby
NR
system
is
B-type,
then
Dolby
Laboratories
introduced
new
Dolby
C-type
NR
in
1980
which
gives
much
better
noise
reduction
plus
improving
high
range
frequency
response,
so
suggest
to
utilize
Dolby
C-type
NR
when
you
make
new
recording
with
this
cassette
deck.
Leave
this
selector
in
its
“B”
position
when
recording
or
playback
in
Dolby
B-type
NR
mode
and
depress
it
in
its
“C”
position
in
Dolby
C-type
NR
mode.
Principle of DOLBY NR System
The
Dolby
NR
system
functions
so
that
it
automatically
increases
recording
levels
of
medium
and
high
frequencies
when
the
recording
signal
level
is
lower
than
the
specified
level
(encoding),
and
automatically
reduces
the
output
levels
to
the
normal
level
during
playback
(decording).
In
this
way,
the
tape
hissing
noise
is
remarkably
reduced
without
affecting
the
sound
quality.
The
Dolby
NR
system
used
in
your
Tape
Deck
improves
S/N
ratio
by
about
5
dB
at
1
KHz
and
about
10
dB
at
10
KHz
in
B-type
and
by
about
20
dB
on
the
most
frequency
range
in
C-type.
Further
more
C-type
has
the
anti-saturation
network
which
reduces
the
affects
of
high
frequency
saturation,
improving
high
range
frequency
response.
10

Because
Dolby
C
Noise
Reduction
gives
substantially
better
results
than
no
noise
reduction
or
Dolby
B
NR
we
suggest
it
be
used
for
all
tapes
which
will
be
played
back
on
your
cassette
deck.
Recordings
made
for
auto
or
portable
play
back
may
sound
better
with
or
without
Dolby
NR,
Experiment.
NOTE:
1.
Most
commercially
available
pre-recorded
tapes
with
“OQ”
mark
are
recorded
with
Dolby
B
NR
or
recorded
with
Dolby
C'NR
will
have
“2”
mark.

Set
this
selector
to
the
same
position
in
both
recording
and
playback
modes.

RECORDING LEVEL ADJUSTMENT
High
recording
level
is
recommended
to
reduce
tape
noise,
but
overloaded
and
distorted
tape
result
if
the
level
is
too
high.
Generally,
recording
levels
should
be
adjusted
so
that
the
level
meters
indicate
as
fully
es
possi-
ble
to
the
proper
level
shown
at
below
for
NORMAL
and
CrO:
tape
except
METAL
tape.
The
METAL
tape
permits
recording
level
up
to
+3
dB
higher
position

the

Synchro Dubbing from Deck A to Deck B
. Turn the power on.
Load a pre-recorded cassette into the cassette holder on Deck A.
. Set the Deck A EQ selector to appropriate position according to the type of tape to be played.
. Load a blank cassette (or pre-recorded cassette to replace with new recording) into the cassette holder on
Deck B. Check to make sure that the cassette erasure tab on the upper edge has not been removed.
. Set the Deck B TAPE selector to appropriate position according to the type of tape to be recorded.
. Set the MODE switch to the DUB position.
. Set ind DUBBING SPEED selector to a desired position; NORMAL or HIGH speed.
. Depress the PAUSE button of Deck A first.
. Depress the PLAY button of Deck A second, then Deck A is in the standby playback mode.
. Depress the RECORD button of Deck B third, then the PAUSE button of Deck A is automatically released
and synchro dubbing starts.
11. To skip any selection of Deck A, depress the PAUSE button of Deck B during dubbing and depressing
it again when you are ready for dubbing the next selection.
12. To stop dubbing, depress the STOP/EJECT buttons of both Decks simultaneously.
NOTE:
¢ In dubbing mode, the Dolby NR circuits are automatically bypassed for copying a tape, but operative for
the monitoring output.
If the original tape is recorded without Dolby NR, it makes a copy recorded without Dolby NR. In this case,
set the Dolby NR switch to OFF for monitoring purpose.
If the original tape is recorded with Dolby NR, it makes a copy recorded with Dolby NR. In this case, set
the Dolby NR switch to ON for monitoring purpose.
¢ In dubbing mode, it makes a copy as the same level as that of original tape automatically, but sometimes
it may make a copy with a little higher or lower level because of different recording level between brand
names of tape.
e Even HIGH speed dubbing makes a copy one and a half times faster than NORMAL speed, we recommend
to dub at NORMAL speed if better sound quality is required.
¢ During dubbing please don’t change speed. It may cause tape click noise recorded.

CLEANING
OF
HEADS
AND
TAPE
PATH
Generally,
cleaning
after
every
10
hours
of
operation
will
be
sufficient.
However,
all
surfaces
over
which
tape
travels
should
be
cleaned
before
making
high
quality
recordings.

4. Replace the door lid.
Do
not
insert
a
cassette
until
the
cleaner
has
completely
dried.

DEMAGNETIZING HEADS
Residual magnetism will gradually build up on the heads through continuous use and cause erasure of high
frequencies and hiss. The heads and metallic parts of the tape path should be demagnetized after 20-30 hours
of operation with a commercially available head demagnetizer. Be sure the cassette deck is turned off.
CLEANING CABINET
Clean
the
cabinet,
panel
and
controls
with
a
soft
cloth
lightly
moistened
with
mild
soap
solution.
Do
not
use
any
type
of
scouring
powder
or
solvent
such as alcohol
or
benzine.

CARE
¢
From
a
tape
length
point
of
view,
most
of
the
tape
manufacturers
use
C-60’s
(30
min
x
2)
as
their
standard,
some
C-90’s
(45
min
x2)
and
C-120’s
(60
min
x
2)
less
often.
If
the
length
of
the
tape
is
longer
it
can
stretch
and
become
soft.
We
would
like
to
recommend
that
you
use
C-60
or
C-90
tapes
for
better
quality
sound
and
safe
tape
operation.
C-120
cassette
tape
is
so
thin
and
soft
that,
if
the
capstan
or
pinch
roller
is
even
slightly
dirty,
it
often
coils
around
the
capstan
or
pinch
roller
and
results
in
tape
breakage,
so
if
you
use
C-120
tape,
perfectly
clean
capstan
and
pinch
roller.
Before
inserting
a
cassette,
take
up
the
slack
of
the
tape
to
prevent
it
from
becoming
entangled
around
the
capstan.
Avoid
touching
the
tape
surface
of
a
cassette.
Protect
it
from
dust
by
storage
in
a
case.
Even
minor
dirt
of
dust
could
cause
contamination
of
the
heads
resulting
in
noise
and
sound
drop-out.

tortion
of

could
occur.
Do not expose a cassette to direct sunlight,
extreme cold temperature or moisture.
Avoid rewinding or winding in fast forward mode
just before storing a cassette tape as this may cause
stretching of the tape edge if it is left over a period
of time.
Do not stick any thick paper or tape on the cas-
sette, as this may effect tape contact with the head.
METAL Tape is the latest development in cassette
technology, an advance that allows the cassette
deck to complete on equal audio terms with the
new generation of amplifiers, tuners and turn-
tables. Comparing with CHROME tape, METAL
tape has better signal to noise ratio, wider
frequency response and higher MOL (maximum
output level).
