An
optional
cord with
DIN connectors
may
be used
for
interconnecting
the
deck and
stereo
amplif
ier
system
with a
single
connecting
cord.
Note:
When
using
the
DIN cord,
recording
levels
are
set
the
MIC
control
and MIC/LINE
mixing
cannot
performed.
If use
of the
DIN
cord
results
in insufficient
volume
level
or
inferior
tone
quality,
remove the
cord
and use
the
four
cables
furnished
with
the equiprnent.
Sound
recordings
are
made
in a strip
on
the
magnetic
surface
of
a recording
tape.
This
magnetized
strip
is called
the
"Track".
The
full tape
width
divided
by two
is
called
a
"2"
ttack
recording,
and the
full
tape
width
divided
into
quarters
is
called
a"4"
trackrecording.
"2"
Track
recording
2
Track
recording
is mainly
employed
in Radio
Stations
and professional
recording
studios
for
stereo
recording,
in
this
case both
tracks
are recorded
simultaneously
and
in the
same direction.
2 track recording
in the
home
is usually
done one
track
at a time
and
is
played
back
monaurally.
"4"
Track
recording
(Monaural)
In this
mode,
each of the
four
tracks
is recorded
individually.
At the
end of the
tape
the reels
are
inter-
changed
between
left
and
right
and
the
next track
is
recorded.
The order
in rvhich
the
tracks
are recorded
is
ii
l,
*4,
*3
and
lastly
f
2.
(Note)
With
tape threaded
on
the
machine
the tracks
are
numbered 1
through
4,
from the top
to the bottom,
viewed
from the
base
side of the tape.
Four track
recording
gives
maximum playback
time,
however,
the
benefits
of stereo
reproduction
are
lost.
"
4"
T r ack
recording
(
Stereophonic)
In
this
mode two
tracks are
recorded
simultaneously,
on
the first pass
of the
tape, tracks
f
I
and
f
3
are recorded.
The left and
right
reels are then
interchanged
and
tracks
#
2
and
#
4 are
recorded.
The left
channel
sound will
be on
tracks
#
I
and
# 4
and the right
channel
sound will
be on
tracks
# 2 and
# 3. Four track
recording
in stereo
will
provide
the best possible
stereophonic
repioduction
and
ii
the
most widely used
recording
method today.
Playback
compat
ibility
A
four
track
stereo
tape deck
can
play
back
both 4 track
and 2 track
tapes
and
from the
point
of
compatibility
has
the
widest possible
range of
utilization.
When playing
a
2
track stereo
tape on
a 4 track
recorder,
track
#
1
will
be
completely
covered
by the
head,
track
# 2 however
will
be
slightly
off
alignment
but
stereo
can still
be
enjoyed
by
compensating
for the
slight loss
of
# 2 track
volume
with
the volume
or balance
controls.
On the
other
hand
a four
track tape
cannot
be
played
back on
a two
track
(Monaural)
recorder
as
both tracks
#
I and
#
2 will
be reproduced
together
resulting
in
mixed
unintelligible
sound.
