e ATRS (Automatic Tape Response System)
The
microprocessor
controlled
ATRS
unit
incorporated
in
this
deck
automatically
detects
the
optimum
bias,
equalization
and
recording
level
for
any
tape
so
that
a
flat
frequency
response
is
achieved
with
minimum
distortion
and
the
widest
possible
dynamic
range.
The
results
of
the
test,
which
takes
10
seconds,
are
held
in
memory
and
can
be
recalled
whenever
required.

is
also
easy.
Logic Control/Feather-touch buttons
The operation controls are feather-touch buttons; just touching them is
enough, you don’t have to press them. ICsin the logic circuit make it possi-
ble to change over directly from fast-forward and rewind to playback
without damaging the tape. In the same way, you can change over from
playback to fast forward or rewind without having to worry about damaging
the tape. :
Double Dolby* Noise Reduction System
The Dolby NR system improves the signal-to-noise ratio by approximately
10 dB without affecting frequency response. With the double Dolby NR
system used in this 3-head deck, when recordings are made with Dolby NR,
they can be monitored after recording and are treated by the second Dolby
NR circuit before being heard.

A

is
used
in
the

to
make
further
im-
provements
in

this
also
reduces
noise
in
playback.
Dual capstan system
This
further
stabilizes
tape
speed
and
tape/head

Fluctuations
in

caused
by
uneven

are
eliminated.
REC/MUTE switch
Pressing
this
button
during
recording
leaves
blank
sections
on
the
tape.
While
the
button
is
pressed
the
tape
transport
continues
to
operate
but
the

is
cut.
Use
it
to
leave

Auto-rewind play/stop facility
At

whether
the

be
rewound,
and
if
it
is
to
be

whether
it
is
to
stop
after
being
rewound
or
enter
the

mode,
is
selectable.
This
is
very
convenient
if
you
want
continuous
background music at a party.

:
When
the
tape
reaches
its
end
in
any
mode,
the
full
auto-stop
mechanism
operates
to
switch
off
the
mechanism
so
that
the
tape
is
not
damaged.
Memory counter
If
you
set
the
counter
to
000’
before
you
start
recording
and
the
memory
switch
ON
when
rewinding,
the
tape
will
stop
when
the
counter
reaches
1999"
in
the
rewind
mode.
Rewinding
to
the
start
of
a
recording
lets
you
listen
to
a
recording
immediately
you
have
made
it.
Used
together
with
the
auto
rewind
mechanism,
this
makes
flexible
operation
possible.

with
a
timer
facility
which
can
record
when
you

With
an
external
audio
timer
connected,
automatic

is
possible.
This

The D-3300M incorporates the innovative ATRS using a microprocessor which
makes it possible to achieve the best possible performance from any tape.
The optimum bias, equalization and recording sensitivity of any particular tape are
detected so that recording and playback with any tape has optimum frequency
response, minimum distortion and the most stable output level possible.
ATRS is not used in the play mode. .

tape, after which the tape is rewound to the position at which the test started,
and the deck enters the stop mode with the test data stored in memory.
. Adjust the level with the Recording level controls @) then press the Record but-
ton (8) and Playback button @) simultaneously to start recording with optimum
bias and equalization.
¢ ATRS cautions!
The Tape select buttons 61) are inoperative once the test has started. Be sure to
press the correct one before the test.
Use the middle of the tape for optimum ATRS testing. Be careful not to use the
leader tape for testing. If the leader tape or bad (worn, non-standard) tape is us-
ed for ATRS testing, precise data cannot be obtained so that ATRS’s operation is
automatically stopped, the TEST START lamp starts flashing to indicate an error
and the deck enters the stop mode.
When the operation button is pressed during ATRS testing, ATRS circuit releases
and the mechanism operation has priority.

METAL TAPE
Metal
tape
is
coated
with
a
magnetic
material
whose
main
components
are
malleable
iron
particles
(Fe)
on
polyester
base
material.
With
its
superb
magnetic
characteristics,
the
frequency
response
of
cassette
decks
is
improved
(especially,
the
dynamic
range
at
high
frequencies
is
widened),
the
maximum
recording
level
is
boosted
and
distortion
is
reduced.

but
the

Cautions
on
the
use
of
metal
tape:
1.
The
coating
of
magnetic
powder
is
not
even
with
some
Metal
Tape
causing
level
variation.
It
is
recommended
to
carefully
clean
the
heads,
capstans
and
pressure
rollers
using
a
cotton
bud
moistened
with
alcohol
after
the
unit
has
been
used
for
several
hours.
Especially
be
careful
when
the
ATRS
testing
is
performed.
(Be
careful;
when
excessive
force
is
applied
to
the
head,
it
may
cause
deteriora-
tion
of
the
high
frequency
response.)

the

When
only
one
side
of
the

is
to
be
protected,
with
the
side

Precaution:
\f
a
tape
is
played
several
times
continuously,
especially
if
thin
tape
(C-90,
C-120)
is
used,
the
tape
might
be
wound
too
tightly
on
the
reel
and
cause
the
tape
speed
to
fluctuate.
In
order
to
avoid
this,
it
is
recommended
to
tap
the
cassette
several
times
lightly
against
a
table-top
19

which
will
loosen
the
tape
on
the
reel.
The
tape
should
not
be
too
loose.
Especially
after
fast
forwarding
or
rewinding
a
C-90
or
C-120
cassette,
the
slack
should
be
taken
up
by
inserting
a
pencil
or
other
object
in
the
spindle
hole
and
the
tape
tightened
to
prevent
looping.
4-Track Record/Playback: After recording or playing back one side of the
cassette,
remove
the
tape
by
depressing
the
Eject
button
5),
turn
the
cassette over and insert it again. Then, the tape can be used again for
the same time as the first side.
Due
to
the
slow
speed
of
cassette
decks,
tape
hiss
occurs.
This
is
not
audible
at
maximum
output
level
but
considerably
degrades
the
playback
quality
of
low
level
passages
of
recorded
material.
By
using
the
Dolby
NR
system
(named
after
the
inventor),
it
is
now
possible
to
substantially
reduce
tape
hiss
so
that
it
is
practically
inaudible
during
playback.
With
the
Dolby
NR
system,
during
recording,
the
level
of
the
low
passages
is
increased
considerably;
during
playback
these
passages
are
reduced
to
their
original
level.
Therefore,
the
tape
hiss
is
also
reducted
by
the
same
amount
and
is
not
audible
during
playback.
Before
playback
of
a
cassette,
it
should
be
ascertained
if
the
Dolby
NR
switch
@)
is
set
in
the
proper
position:
*
Cassettes
recorded
through
the
Dolby
NR
circuit
must
be
played
back
in
the
Dolby
NR
mode
(if
played
back
with
normal
playback
equalization,
the
sound
seems
too
sharp.)
*
Normal
recordings
should
not
be
played
back
through
the
Dolby
NR
system
(if
played
back
with
the
Dolby
NR
equalization,
the
sound
will
seem
‘“‘muddy”’).
Generally,
the
optimum
adjustment
of
the
recording
and
playback
calibration
is
im-
portant
for
satisfactory
functioning
of
the
Dolby
NR
system.
This
adjust-
ment
is
done
at
the
factory
prior
to
shipment
using
calibrated
test
tape
and
special
equipment.

Music
1.
What
the
Dolby
System
does
first
Music is composed of sounds of different.
loudness separated by intervals of silence.
Loud and soft sounds are here shown as long
and short lines. The music shown in this
diagram starts loud and gradually becomes
very quiet.
2 Noise
Any recording tape, even of the best kind,
makes a constant hissing noise when played.
At the very slow speeds and narrow track
widths used in cassette tapes, tape noise is
much more noticeable than it is in professional
tape recordings, although even there it is a
problem.
3. Music and Noise
When a tape recording is played, noise from
the tape obscures the quietest musical sounds
and fills the silence when no sound should be
heard at all. Only when the music is loud the
noise is not usually heard; however, tape noise
is so different from music that it sometimes
can be heard even then.
20
Before the recording is made, the Dolby
System “‘listens” to the music to find the
places where a listener might later be disturbed
by hiss from the tape. This happens mainly
during the quietest parts of the music. When
it finds such a passage, the system auto-
matically increases the volume so that music
is recorded at a higher level than it would be
normally.
2. The Recording
In a Dolby System recording the parts of the
music which have been made louder stand
out clearly from the noise. Thus recordings
sound brilliant and unusually clear even
when played back without the special Dolby
System circuit.
3. What the Dolby System does
during playback
When tapes are played on a high-fidelity tape
deck equipped with the Dolby System
circuit, the loudness is automatically reduced
in all of the places at which it was increaseed
before recording. This restores the music to
its original level again.
At the same time, the noise which has been
mixed with the music is reduced in level and
this is by the same amount usually enough to
make it inaudible.
