ABOUT
THE
PEAK-SIGNAL-CHECK
SWITCH
(Refer
to
fig.
7.)
@ Adjustment of the recording level
To
adjust
the
recording
level
on
ordinary
tape
decks,
the
level
is
adjusted
so
that
the
indication
needles
of
the
level
meters
fluctuate
at
a
point
as
near
to
(but
below)
the
“0”
point
as
possible.
Because
this
unit
has
a
PEAK-SIGNAL-CHECK
switch,
however,
the
adjust-
ment
of
the
recording
level
can
be
made
as
described
below
for
best
results.
1.
Adjustment
of
the
recording
level
by
using
the
PEAK-SIGNAL-
CHECK
switch
- @ Set the PEAK-SIGNAL-CHECK switch to the “OUT” position,
and
adjustso
that
the
indication
needles
do
not
fluctuate
beyond
the “O dB” point.
,
@
Next,
set
the
PEAK-SIGNAL-CHECK
switch
to
the
“IN”
posi-
tion.
Then,
at
a
time
when
the
music
is
pulsating
and
such
rhythm
is
reaching
its
peak,
set
the
MICROPHONE
LEVEL
controls
or
LINE
INPUT
LEVEL
controls
to
a
position
which
will
restrain
the
needles
from
moving
beyond
the
“+6
dB”
point
(referring
to
the
“PEAK
IN’
portion
of
the
meters).
By
so
doing,
the
recording
can
be
made
without
distortion.
@®
Occasionally,
set
the
PEAK-SIGNAL-CHECK
switch
to
the
“OUT”
position
and
confirm
that
the
needles
do
not
move
beyond
the
“O
dB”
point
of
the
upper
part
of
the
meters.
2.
Difference
of
indication
needle
movement
caused
by
setting
the
PEAK-SIGNAL-CHECK
switch
to
the
“IN”
and
‘‘OUT”
positions
Because
the
response
to
sound
signals
by
indication
needles
of
ordinary
level
meters
is
slow,
the
actual
level
of
momentary
signals
is
not
accurately
indicated
by
such
meters.
This
means,
of
course,
that
there
is
always
the
possibility
that
recordings
may
be
distorted
by
large
signals
which
are
momentary.
The
peak
level/VU
meters
of
this
unit
include
a
special
PEAK-SIGNAL-CHECK
switch
which,
when
set
to
the
“IN”
position,
results
in
the
indication
by
the
meters
of
the
level
of
sounds,
even
momentary
sounds,
with
extremely
precise
accuracy.
The
peak
level/VU
meters
of
this
unit
each
have
dual
scale
indica-
tions
which
should
be
read
in
the
following
way:
With the PEAK-SIGNAL-CHECK switch set to the “IN” position,
the
scale
is
read
up
to
the
+6
dB
mark
on
the
lower
part
of
the
meters.
With the PEAK-SIGNAL-CHECK switch set to the “OUT” position,
the scale is read up to the +3 dB mark on the upper pari of the
meters.
The needle fluctuation for momentary sound and for continuous
sound is shown in figure 7.
MONITORING
“Monitoring’’ means to listen, using headphones, to the sound being
recorded at the same time it is being recorded. This is very convenient
for actual aural confirmation of the material being recorded.
To monitor, connect stereo headphones (89) to the HEADPHONES
jack (HEADPHONES).
Note:
fn the same way as for playback, an amplifier can also be used for
monitoring. Note, however, if the recording is being made via a con-
nection made tothe RECORDING/PLAYBACK connection socket, that
monitoring can be done only with headphones.
HOW TO USE THE PAUSE BUTTON
The
PAUSE
button
is
used
for
instantaneous
temporary
stops
and
starts
of
tape
movement
during
recording
or
playback.
When
this
button
is
pushed
to
the
depressed
position,
it
remains
in
that
position
(and
the
tape
stops)
until
it
is
pushed
once
again
(and
the
tape
resumes
movement).
The
PAUSE
button
of
this
unit
has,
in
addition,
one
more
special
func-
tion
which
is
necessary
for
a
recording
or
playback
made
in
conjunction
with
a
timer
connected
to
this
unit.
Thus,
by
pushing
the
PAUSE
button
while
the
power
to
this
unit
is
off,
and
preparing
the
unit
for
recording
or
playback,
the
PAUSE
but-
ton
will
be
automatically
released
and
the
tape
will
begin
to
move
when
power
to
the
unit
is
resumed
(as
controlled
by
the
timer).
RECORDING
WITH
A
TIMER
(Refer
to
fig.
9.)
(Timer recording of FM broadcasts)
1. Connections
Connect the power source. (Refer to figure 9.)
Connect the sound source. (Refer to figure 6.)
2.
Insert
a
blank
tape
cassette
into
this
unit,
and
then
push
the
power
switch
to
turn
on
the
power.
3.
Tune
to
the
FM
broadcasting
station
from
which
the
broadcast
will
be
later
made,
and,
with
the
PAUSE
button
of
this
unit
de-
pressed,
then
push
the
RECORD
button
and
the
PLAY
button
and
make
adjustment
of
the
recording
level.
4.
Set
the
timer
to
the
time
at
which
the
recording
should
begin.
lf
the
timer’s
power
was
on,
it
will
now
turn
off
(although
the
opera-
tion
of
the
timer
itself
will,
of
course,
begin).
These
steps
complete
the
preparations
necessary
for
recording
by
a
timer.
When
the
timer
reaches
the
time
to
which
is
was
set,
power
will
pass
through
the
timer
to
this
unit,
thus
releasing
the
PAUSE
button,
and the recording of the FM broadcast will begin.
Notes:
1.
When
the
tape
reaches
its
end,
the
automatic-stop
system
will
function
and
the
operation
controls
will
return
to
their
original
positions.
If,
however,
the
timer
used
is
the
type
which
can
be
set
to
turn
off
the
power,
and
it
is
set
to
turn
off
the
power
before
the
tape
reaches
its
end,
the
mechanism
of
this
unit
will
not
bereleased
when
the
power
is
turned
off,
and
it
is
possible
that
the
pressure
roller
may
in
that
way
become
deformed.
It
is
for
this
reason
re-
commended,
if
such
a
timer
is
used,
that
the
tape
be
allowedto
move
until
it
reaches
its
end
and
thereby
causing
the
automatic-stop
system
to
function
before
the
power
is
turned
off
by
the
timer.
.
To
stop
the
tape
movement,
if
desired,
during
the
recording.
simply
push the STOP button of this unit.
PLAYBACK WITH A TIMER
1. Insert the already-recorded tape cassette into this unit and make
connections to the power source and for playback.
2.
Make
a
trial
playback
and
adjust,
if
necessary,
the
volumea
nd
tone
quality
(by
using
controls
on
the
amplifier
to
which
this
unit
Is
connected)
to
the
level
desired
when
the
timer
playback
begins.
3. Rewind the tape to the point from which the timer playback Is to
begin, push the PAUSE button, and then push the PLAY button.
4. Set the timer to the desired time for beginning of the pl ayback.
(Depending
on
the
type
of
timer
used,
the
power
to
the
timer
will
be
turned
off
automatically—if
it
was
on—although
the
operation
of
the
timer
itself
will,
of
course,
begin.)
These steps complete the preparations necessary for playback by a
timer.
When
the
timer
reaches
the
time
to
which
it
was
set,
thep
layback
will begin.
