Setting
up
for
Recording and Playback
Connections
• Connect
the white
plug of the
cassette interface
to
the
MICROPHONE
jack
of the tape recorder.
If
you
are
using
a
stereo tape recoreder, connect
it
to the right
channel.
• Connect
the black plug of the cassette
interface to the
EAR-
PHONE, MONITOR,
or
EXTERNAL
SPEAKER
jack.
In
case
of
a
stereo tape recorder, use the
same
channel
as
used
for
recording.
•
Connect
the gray plug
to the
remote
control jack of the tape
recorder.
•
Normally,
the
system
(cassette interface
and
tape recorder)
works
properly with
all
three plugs connected
to the cassette
interface.
However, some
tape recorders
may
develop
noise
when
the
white
and
black plugs
are
connected
at
the
same
time.
If
so,
connect only
the
white plug
when
recording (com-
puter
to tape),
and
only
the black plug
when
playing back
(tape to
computer).
Recording
level
adjustment
If
your
tape recorder has an
automatic
level
control, turn
it
on.
»lf
not, adjust
the
level
control
manually
as
follows:
Record
test data,
and, while doing
so,
adjust the
level
control so
that the
VU
meter
reads zero.
Note:
If
the
level
meter
deflection
is
extremely wide, do
not
use that particular tape recorder.
'
Output
level
adjustment
•
Set the
volume
control higher than
you would
usually
when
listening to
music.
The
position
of the
volume
control
should
be
between
the
middle and
maximum
points. (Usually the
maximum
point
works
best.)
•
In
the
case of
a
stereo
tape recorder, turn the balance control
to the
extreme
position of the
channel
you
are using
(i.e.
the
channel the black plug
is
connected
to).
