Units shipped to Australia are designed for operation
on 240 V AC only.
To ensure safe operation the three-pin plug supplied
must be inserted only into a standard three-pin power
point which is effectively earthed through the normal
household wiring. Extension cords used with the
equipment must be three-core and be correctly
wired to provide connection to earth. Wrongly wired
extension cords are a major cause of fatalities. The fact
that the equipment operates satisfactorily does not
imply that the power point is earthed and that the
installation is completely safe. For your safety, if in any
doubt about the effective earthing of the power point,
consult a qualified electrician.

M@ RECORDING LEVEL ADJUSTMENT
The most important factor for good recording
results is the recording level adjustment. If the
recording level is set at maximum, the signal-to-
noise ratio (S/N) and the dynamic range(range of
sound volume) will improve, but if it is set too
high, the sound quality will deteriorate. On the
contrary when the recording level is set too low in
order to avoid distortion, tape hiss noise becomes
too evident. Even among tapes of the same type,
the tape characteristics may differ according to
maker and kind. It is therefore important to
determine the optimum recording level for each
tape used, in order to obtain good recordings by.
fully utilizing the tape characteristics.
The
optimum
recording
level
depends
on
the
type
of
music
to
be
recorded
and
also
on
the
type
of
tape
used.
To
obtain
better
recordings
that
make
the
most
of
the
tape
characteristics,
judge
the
playback
sound
quality
by
actually
listening
to
your
recording.
Generally,
adjust
the
recording
level
so
that
the
level
meters
indicate
around
the
0
dB
point
for
normal
or
chrome
tapes
or
the
+3dB
point
for
metal
tapes

the
highest

DOLBY
HX
PROFESSIONAL
HEAD
ROOM
EXTENSION
(DOLBY
HX
PRO)
1.
Dolby
HX
PRO
is
professional
recording
bias
system
which
are
now
available
in
some
of
home
cassette
recorders
improving
dynamic
range
and
signal
clarity
for
life-like
sound
quality.
When
recording
audio
signals
which
contain
high-frequency
components,
these
components
influence
the
bias
and
decrease
the
high
recording
frequencies.
(If
the
amount
of
bias
is
great,
high
frequencies
are
decreased,
while
on
the
other
hand,
if
the
amount
of
bias
is
small,
high
frequencies
are
increased,
resulting
in
a
corresponding
increase
in
distortion.)
The
Dolby
HX
Pro
system
responds
to
high
or
low
frequencies
to
regulate
the
oscillation
of
the
bias
level
added
to
the
recording
head,
thus
providing
a
stable,
effective
bias
to
the
audio
signals
being
recorded.
When
an
audio
signal
contains
a
large
number
of
high-frequency
components,
the
bias
is
held
to
a
low
value
and
deterioration
of
high
frequencies
is
avoided,
where
as
for
low
frequencies,
the
bias
is
added
at
a
fixed
rate.
Bias
is
thus
added
at
the
optimum
rate
for
both
high
and
low
frequencies.

The
unit
incorporates
the
Dolby
HX
Pro
system
which
automatically
adjusts
itself
not
only
for
normal,
CrO>,
and
metal
position
tapes
but
also
for
right
and
left
channels
independently.
Since
the
system
is
automatically
engaged
during
the
recording
process
only,
the
audiophile
can
enjoy
the
full
benefits
of
any
tape
without
worrying
about
proper
adjustment
of
switches
and
encoding/decoding
controls.

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
level
to
the
normal
level
during
playback
(decoding).
In
this
way,
the
tape
hiss
noise
is
remarkably
reduced
without
affecting
the
sound
quality.
The
Dolby
NR
system
used
in
your
cassette
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.
Furthermore
C-type
has
the
anti-saturation
network
which
reduces
the
affects
of
high

saturation,
improving
high

M@ NOTES ON CASSETTE TAPE
* Before loading a cassette tape, take up the slack in
the tape to prevent if from becoming entangled
around the capstan.
ENGLISH
After the recording has been finished, remove the
tab to prevent the recorded contents from being
erased or recorded on accidently.
For side B For side A
To rerecorded after tabs have been removed,
cover with adhesive tape.
Do not store the tapes in direct sunlight or near
equipment that generates heat. Keep the tapes
away from any magnetic fields.
Do not touch the tape surface and store the tapes in
their cases after use. Dust can cause contamination
of the heads resulting in noise.
M@ CLEANING THE HEAD SECTION
Clean the head section about every 10 hours of use
using the commercially available head cleaning tape.
¢ For better recordings, you should clean the head
section before every recording.
* After cleaning the head section, do not load a tape
until the cleared section is completely dry.
M DEMAGNETIZING THE HEAD
Demagnetize the recording/playback head about
every 10 hours of use using a commercially avaiable
demagnetizer so that the magnetized head may not
cause the sound to be deteriorated.
