ONE-MICRON
GAP
HEAD
AKAI’s
one-micron
gap
head
is
responsible
for
an
amazingly
important
difference
in
tape
recording.
It’s
the
difference
between
ordinary
performance
and
the
highest
possible
quality
perfection.
Just
what
is
a
one-micron
gap
head?
It’s
a
head
with
a
width
of
only
one
astounding
micron.
Until
now
two
or
four
micron
gap
heads
have
been
the
standards
for
comparing
tape
recorders.
However,
AKAI
has
pushed
ahead
and
narrowed
the
head
gap;
thus
narrowing
the
difference
between
tape
recording
results
and
actual
sound.
The
AKAI
perfected
one-micron
gap
head
has
these
distinctive
advantages
over
heads
with
wider
gaps:
(A)
Excellent
frequency
response
even
at
low
tape
speed.
(B)
Clear,
high
pitched
sound
can
be
regenerated
as
a
frequency
tone
and
recorded
smoothly
with
a
minimum
of
distortion.

STEREO
SELECTOR
The
CR-80-SS
(CR-80D-SS)
utilizes
a
unique
change-over
system
from
4-channel
to
2-channel
stereo
or
vice-versa.
When
a
tape
is
loaded,
the
unit
is
automatically
switched
for
2
or
4-channel
operation
depending
upon
the
tape
and
the
Stereo
Selector
Indicator
Lamp
lights
accordingly.
Note
that
when
a
2-channel
tape
is
inserted
into
the
cartridge
receptacle,
only
the
two
front
channels
are
set
for
operation
and
the
“2-CH”
lamp
lights.
When
a
4-channel
tape
is
inserted,
all
4-channels
are
set
for
4-channel
operation
and
the
“4-CH”
lamp
lights.
In
case
4-channel
operation
is
desired
with
a

depress
the
Stereo

for
change-over
to
4-

2
or
4
of
which
are
used
at
a

How¬
ever,
in
the
case
of

AKAI
SURROUND
STEREO
Just
as
2-channel
stereo
sound
reproduction
meant
the
exodus
of
flat
monaural
sound,
so
does
AKAI’s
epoch
making
SURROUND
STEREO
eliminate
the
inability
to
pick
up
and
reproduce
pure
concert
hall
sound.
The
CR-80-SS
is
equipped
with
4
speaker
jacks
and
a
built-in
4-channel
amplifier
(The
CR-80D-SS
is
a
4-channel
surround
stereo
tape
deck.
For
playback,
a
4-channel
external
stereo
amplifier
(or
two
2-channel
stereo
amplifiers)
and
2
sets
of
speakers
are
required).
For
SURROUND
STEREO,
this
new
4-channel
cartridge
stereo
system
uses
4
signal
paths
(4
sound
tracks)
in
the
program
material
and
for
playback,
4
speakers
are
positioned
to
surround
the
listener.
Each
speaker
delivers
separate
sound
depending
upon
microphone
placement
during
recording
and
provides
the
listener
with
a
realistic
“SENSE
OF
PRESENCE”.
This
4-dimensional
sound
reproduction
makes
ordinary
stereo
seem
insufficient.
This
move-up
to
Surround
Stereo,
though
a
real
step
forward
in
the
recording
world,
does
not
mean,
however,
that
your
2-channel
recordings
are
obsolete.
The
CR-80-SS
(CR-80D-SS)
is
compatible
with
2-channel
stereo
as
well.
A
unique
change-over
system
is
utilized
to
automatically
set
recorder
(deck)
for
2
or
4
channel
operation
depending
upon
the
tape
being
used.

PRECAUTIONS
Model
CR-80-SS
(CR-80D-SS)
is
constructed
of
the
finest
materials
and
with
proper
care
will
bring
you
many,
many
hours
of
musical
listening
pleasure.
We,
therefore,
strongly
urge
you
to
read
this
manual
thoroughly
before
attempting
operation.
The
conditions
listed
below
do
not
indicate
mechanical
failure
of
your
unit.
If
your
machine
exhibits
any
of
these
conditions,
please
take
the
indicated
action:
1.
Loss
of
sensitivity
and
tone
quality
*
Dirty
Erase
Head
(Clean
erase
head)
*
Dust
adhering
to
recording/playback
head
(Clean

*
AC
power
lower
than
the
voltage
to
which
your
machine
is
adjusted
(Check
voltage
input
and
adjust).
2.
Machine
will
not
record
(play)
*
Check
positions
of
controls
and
plugs
and
posi¬
tion
of
Input
Selector
Switch.
The
following
notes
are
provided
for
your
convenience:
1)
The
use
of
new
tapes
will
result
in
the
best
recordings.
2)
Should
your
machine
need
service,
take
it
to
your
nearest
authorized
AKAI
Service
Agent
or
inquire
at
the
Service
Department
of
AKAI
Company,
Tokyo
Japan.
3)
Your
machine
needs
constant
voltage
for
optimum
perfor¬
mance.
4)
In
recording,
if
the
sound
sources
are
so
far
away
from
the
microphones
that
the
volume
controls
must
be
turned
up
to
maximum,
some
hum
or
noise
will
inevitably
be
recorded.
A
test
recording
is
recommended
before
at¬
tempting
a
final
recording.
5)
Insert
cartridge
properly
(if
up-side-down
your
recorder
will
not
operate).
6)
Although
the
motor
of
Model
CR-80-SS
(CR-80D-SS)
is
sufficiently
oiled
for
prolonged
use,
for
maximum
service
and
optimum
performance,
take
your
machine
to
your
local
authorized
AKAI
service
agent
for
occasional
lubri¬
cation.

ERASING
Any
signals
previously
recorded
on

will
be
erased
automatically
as

recording
is
being
made
on
the
same
tape.
For
erasing
only,
set
recorder
to
normal
recording
mode.
No
plugs
should
be
connected
to
the
recorder
Input
Jacks
and
Volume
Controls
should
be
kept
at
minimum
position.
A
Bulk
Tape
Eraser
is
recommended
for
quick
and
complete
erasure.
HEAD
CLEANING
Tape
Oxide/Dust
deposites
cause
90%
of
Tape
Recording
Failures.
For
quality
performance,
it
is
imperative
that
tape
recorder
heads
be
kept
clean
at
all
times.
Dust
and
magnetic
particles
from
the
tape
tend
to
deposit
on
the
heads
after
prolonged
use
of
the
recorder.
This
results
in
poor
head-to-
tape
contact
deteriorating
sound
quality
and
sensitivity.
Such
dust
deposits
cause
drastic
drops
in
recording/playback
levels
and
nullifies
high
quality
sound.
Make
it
a
rule
to
clean
the
heads
every
time
you
use
your
tape
recorder.
