What you should know to protect
yourself
Never touch the pl ug Wi ith wet h
Always pull out by the plug and never the cord.
Only let a qualified professional repair or reassemble the
stereo cassette deck. An inexperienced person might
touch the internal parts and receive a serious electric
shock.
e@ Never put anything, especially metal, into the stereo cas-
sette deck.
Alawar tar: nds
nas
Protect the stereo cassette deck too
@ Use only a household AC power source. Never use a DC
power source.
@ {f water is spilled on the stereo cassette deck, disconnect
it and call your dealer.
@ Make sure that the stereo cassette deck is well ventilated
and away from direct sunlight.
@ To avoid damage to the internal circuits and the external
surface, keep it away from heat (stoves, etc.).
® Avoid using spray type insecticide near the stereo cas-
sette deck as this could damage the finish or cause sud-
den ignition of the insecticide.
@ To avoid damaging the finish, never use paint thinner or
other similar chemicals to clean the stereo cassette deck.
@ Place the stereo cassette deck on a flat and solid sur-
face.
e If you don’t plan to use the stereo cassette deck for a
long period of time, disconnect the power cord.
Dew formation
Dew is the term used for the formation of moisture on the
very important tape transport sections such as the heads
and the capstan, when the deck is used in places where hu-
midity is high, or moved from a cold place to a warm one. If
the deck is used when dew is present, the tape will stick to
the head and be ruined, or it will not be transported properly.
In that case, do not use the deck for approximately one hour
until the deck is acclimatized.
Placement
If the cassette deck and tuner are placed on top of each.
other, humming noise may result during playback. Also beat
noise may result during recording of AM broadcasts. In this
case, the position of the deck should be changed. We re-
commend that the amplifier or a space the size of an ampli-
fier be left between the deck and the tuner.

A Word about cassette tapes
Handling
@
Do
not
touch
the
tape
with
your
fingers
as
high
frequency
signals
cannot
be
recorded
in
places
which
are
not
clean.
Dirty
tapes
may
also
cause
distortion
or
sound
loss
dur-
ing
playback.
®
Do
not
leave
the
cassette
tape
near
equipment
which
generates
a
magnetic
field.
(TVs,
speaker
systems,
etc.)
Tape
slack
and
leader
tape
advancement
Tape
slack
can
cause
the
tape
to
twist
or
tangle
around
the
capstan
and
pinch
roller
and
ruin
important
recordings.
Be-
fore
using
a
cassette
tape,
take
up
tape
slack
with
a
pencil.
Most
cassette
tapes
include
clear
leader
tape
at
the
beginn-
ing.
As
recording
is
impossible
on
this
leader
tape,
it
should
be advanced
before
recording
is
begun.
Storage
e
Always
put
the
cassette
tape
back
into
its
plastic
case
af-
ter
using
it.
Store
it
in
a
dry
place,
away
from
direct
sun-
light,
heat
(stoves,
etc.)
and
equipment
which
generates
a
magnetic
field
(TVs,
speaker
systems,
etc.).
®
Store
the.cassette
tape
with
the
tape
taken
up
at
the
fixed
speed
of
recording
or
playback.
When
the
tape
is
not
taken
up
in
an
orderly
manner
(in
other
words,
fast
for-
warded
or
rewound),
the
tape
might
stretch
or
warp.
e
If
you
are
not
going
to
use
the
cassette
tape
for
a
long
time,
rewind
or
fast
forward
the
tape
once
in
a
while.
This
is
to
prevent
music
signals
from
imprinting
themselves
over
other
music
signals
when
tape
surfaces
are
in
close
contact
for
a
long
time.
Rewinding
or
fast
forwarding
the
tape
also
prevents
moisture
condensation.
Regarding cassette tapes
@
We
recommend
the
use
of
cassette
tapes
specifically
made
for
recording
hi-fi
music.
@
We
do
not
recommend
the
use
of
C-120
(120
minute)
cassette
tapes.
The
tape
is
very
thin
and
can
easily
twist
or
tangle
around
the
capstan
and
pinch
roller.
®
We
do
not
recommend
the
use
of
cassette
tapes
of
poor
quality.
You
will
not
be
able
to
fully
utilize
the
capability
of
your
stereo
cassette
deck
with
this
type
of
cassette
tape.
@
We
do
not
recommend
the
use
of
ferri-chrome
cassette
tapes
for
recording.

What is the auto monitor system?
The
independent
recording
and
playback
heads
in
combina-
tion
with
two
independent
amplifiers
(one
for
recording
and
another
for
playback)
let
you
listen
to
a
recording
as
it
is
be-
ing
made.
This
is
called
tape
monitoring.
By
switching
the
-
auto
monitor
system
during
recording,
you
can
compare
the
just-recorded
music
(TAPE
position)
with
the
source
music
(SOURCE
position).
In
this
way
you
can
make
sure
that
you
have
set
the
recording
input
levels
correctly.
The
tape
moni-
tor
system
of
this
cassette
deck
is
called
an
“Auto
Monitor
System”.
Besides
letting
you
manually
set
the
tape
monitor
system,
it
also
does
it
automatically.
When
the
cassette
deck
is
recording,
the
auto
monitor
system
is
set
automati-
cally
to
TAPE.
During
recording
standby,
it
is
automatically
set
to
SOURCE.
Under
normal
circumstances
there
is
no
need
for
you
to
set
the
MONITOR
switch
yourself.

Operation details —
Bias adjustment
Cassette tapes can be separated widely into 3 types: Normal
position, Chrome (CrOz) position and Metal position.
Recording characteristics vary slightly, even with tapes that
have the same position. For good recording results, precise
adjustment of the tape’s bias is necessary.
This cassette deck is equipped with a BIAS control which is ca-
pable of adjusting the recording bias current from a range of
-20 %to +20 % of the proper bias current for each tape position. —
CLOSED LOOP DOUBLE CAPSTAN
Operation
For bias adjustment, FM inter-sation noise is used as a test
signal.
4 Set your tuner to a point between FM stations.
5
Record the FM inter-station noise at a level of approxi-
mately —20dB. .
During recording, repeatedly press the MONITOR but-
ton to switch between the source sound and the re-
corded sound. |
If the recorded sound has a pronounced higher hiss in
comparison to the source sound, recording bias is set
too low.
If the recorded sound has a lower hiss in comparison to
the sound source, recording bias is set too high.
If both the recorded and source sound are the same,
the recording bias is set to the proper level
4 Adjust the BIAS control as follows:
To increase recording bias ................ ee ceeeeseeeeeeeeesenentees
Turn the control toward +.
To decrease recording bias......... sedacadeysanaubessiveesdsceceeeses
Turn the control toward —.
Record the inter-station noise again and use the MONI-
TOR button to re-check the sound difference.
After recording bias adjustment is completed
Set the cassette deck to the normal recording mode.
Note 7
e Avoid setting the BIAS control to the maximum + or —
positions, since the frequency characteristics of the tape
will change sharply.
@ Normally set the BIAS control to “0” when using one of
the standard reference tapes listed (Refer to page 18).
@ Do not turn the BIAS control during normal recording or
once bias adjustment has been completed.
@ The BIAS control is not effective during playback.

MPX (Multiplex) filter
Set the MPX FILTER switch to =.
When high frequency
rel
signa
stereo recording, use of a noise reduction system alone is
not enough. In this case, it is necessary to use the MPX fil-
ter.
What is the MPX filter?
FM stereo signals contain 19kHz pilot signals and 38kHz
subcarrier signals which convey the left and right channel in-
formation. These signals are necessary, but they must be
removed form the output signals of the tuner. If these signals
are not removed, they can affect the DOLBY NR system.
The MPx filter is designed to remove these pilot tone signals
from the recording.
When to use the MPX FILTER switch
Use this switch only when recording with the DOLBY NR
system. Most high quality tuners have filters to suppress FM
pilot tone signals. With these tuners, you can leave the MPX
FILTER switch OFF. With other tuners, the MPX FILTER
switch should be turned ON. The MPX FILTER switch
should also be turned on when you have monitored the just
recorded music and feel that the sound quality is not right.

Dolby NR system
Set the proper Dolby Noise Reduction sys-
tem before ali recording and playback Op-
erations
When playing back a tape, set the noise reduction selector
switch to the setting that was used when the tape was re-
corded. Set the noise reduction selector switch to OFF for
tapes that were recorded without the use of the Dolby NR
system.
What is the Dolby Noise Reduction (NR)
System?
The DOLBY NR system is a noise reduction system de-
signed to reduce tape noise caused when high frequency
soft sounds are recorded. The DOLBY NR system does this
by lowering the noise floor in order to increase the dynamic
room in the high frequency range above 5kHz.
During recording, the DOLBY NR encoder circuit boosts soft
high frequency sounds, and then during playback the
DOLBY NR decoder circuit lowers what was boosted by ex-
actly the same amount to restore the high frequencies to
their original levels. At the same time, tape noise is lowered .
by the same amount.
The result is reduction of up to 10dB in unwanted tape noise
in the high frequencies. :
What is the difference between Dolby
B-type and C-type NR systems?
B-type : This is the conventional Délby NR system. It boosts
or lowers the low-level signals at high frequencies
‘only (more than 5kHz) and reduces tape noise by
10dB.
Compared to Dolby B NR, it operates at lower fre-
quencies (from 500HZz) for uniform noise reduction
across more of the audible spectrum. Tape noise
is reduced by as much as 20GB.
C-type :
Double process noise reduction system
In a conventional noise reduction system, one circuit acts
both as an encoder and decoder, and is switched to one or
the other accordingly.
The double process noise reduction system has an encoder
circuit in the recording amplifier section, and a decoder in
the playback amplifier section. The double process noise re-
duction system is used in cassette decks with 3 independent
heads (recording, playback, and erase). Therefore, when re-
cording with a noise reduction system, you can immediately
confirm the effect of the noise reduction by monitoring the
just recorded music.

DOLBY HX PRO Headroom extension
system
The Dathy Ly DOP at.
The Dolby HX PRO system (HX stands for Headroom eX-
tension) is a system designed to improve the saturation level
of cassette tapes by controlling the bias current. This im-
proved saturation level means clearer sound when recording
classical music, or other music that contains many instru-
ments. Although it is a Dolby system the HX PRO headroom
extension system should not be confused with Dolby NR as
it is not a noise reduction system.
The Dolby HX PRO headroom extension system is basically
a circuit used in cassette decks that makes use of the fact
that the amount of high frequency energy that the tape can
hold varies according to the amount of bias current present.
Less bias current will result in more headroom for the high
frequencies, but at an increase in low-frequency distortion.
More bias helps to lower distortion, but results in loss of high
frequency “headroom”.
During recording, the Dolby HX PRO headroom extension
circuit monitors the recording signal. When high frequency
peaks that are too high are detected, the bias is reduced
momentarily so that those peaks can be accomodated. This
is especially helpful for signals which have high levels at
high frequencies. When these peaks are no longer present,
the bias is restored to the normal level.
Even when using a normal position tape during recording,
the Dolby HX PRO headroom extension system works to im-
prove its saturation level to almost that of a metal position
tape. Because the system is built into the recording circuits,
it is working whenever recording is taking place. Cassette
tapes recorded with the Dolby HX PRO headroom extension
system can be played back without any problems on any
cassette deck.

Cassette deck maintenance
Keep your stereo cassette deck clean
After prolonged use, parts of your cassette deck which
come into contact with the tape (Heads, capstans, pinch
rollers and tape guides, etc.) become dirty due to oxide from
the tape and other contaminants.
This can fead to such problems as no sound, distorted
sound due to unstable tape transport, etc.
To ensure good performance, you should periodically clean
your stereo cassette deck.
How to remove the cassette lid
1 Press the & button to open the cassette holder.
-) Grasp both sides of the cassette lid and gently pull up to
remove.
Align the cassette lid with the cassette holder and push
it down in the opposite direction of the arrows to replace
the cassette lid.

Cleaning the deck
ae
Use the optional accessory Akai Cleaning kit CK-310 or
cleaning tape.
Dip the cotton swab into the appropriate cleaning fluid (most
cleaning kits contain two types of cleaning fluid; one for me-
tal parts and one for rubber and plastic parts) and wipe the
surface of the heads, tape guides, capstans and pinch roll-
ers.
After cleaning, wipe with a dry cotton swab.
Use your stereo cassette deck only after the parts have
completely dried.
* Use a liquid cleaner exclusively meant for t
best results, always clean your stereo cassett
fore an important recording.
Keeping the head demagnetized
£
S
After much use, slight magnetism can build-up on the re-
cording and playback head causing loss in high frequency
sound and increases in noise. To eliminate this problem you
should periodically demagnetize the head with the optional
accessory Head Demagnetizer AH-15. Damagnetize the
metal parts of the capstan as well.
Before demagnetizing
Turn off your stereo cassette deck.
Keep the cabinet clean too
@ Clean the cabinet with a soft, dry cloth.
@ If the cabinet is excessively dirty, clean it with a mild de-
tergent.
@ Never use paint thinner, etc. to clean the cabinet, as this
may damage the finish.
