Use of microphones
For
microphone
recordings
you
can
connect
two
mono
microphones,
one
to
socket
@)
and
the
other
to
socket
@,
or
a
stereo
microphone
to
socket
@9.
Depending
on
the
position
of
mono/
Stereo
switch
@@,
the
recordings
made
in
each
case
will
be
either
stereo
or
mono.
For
mono
recordings
you
can,
if
desired,
connect
only
one
microphone
to
socket
@9.
For
stereo
recordings
the
microphone
for
the
left
channel
must
face
the
left
and
that
for
the
right
channel
the
right
of
the
sound
source.
For
speech
recordings
the
distance
between
10
mouth
and
microphone
should
be
about
30cm
(12”).
For
music,
trial
recordings
should
be
made
to
determine
the
best
distance.
To
prevent
unwanted
recorder
noise
being
picked
up
by
the
microphones,
these
should
be
placed
away
from
the
recorder.
Introduction to recording
@
The
strength
at
which
the
sound
is
recorded
on
the
tape
determines
the
quality
of
the
sound
obtainable
on
playback.
If
the
recording
level,
as
this
is
called
is
too
low,
too
much
noise
(hiss)
will
be
heard
on
playback.
If
the
recording
level
is
too
high,
distorsion
will
be
heard
on
playback.
The
recording
level
can
be
set
prior
to
commencement
of
recording,
but,
should
circumstances
rule
this
out,
the
level
may
also
be
adjusted
during
record-
ing.
@
Recordings
being
made
from
an
apparatus
having
a
recorder
connection
socket
are
not
usually
affected
by
the
settings
of
the
volume
or
tone
controls
of
that
apparatus.
@
During
recording,
any
previously
recording
on
the
same
part
of
the
tape
is
automatically
erased.
You
can,
however,
erase
a
recording
without
adding
a
new
one
by
keeping
recording
level
control
@
at
’0’
as
you
record.
@
You
can
check
what
is
going
onto
the
tape
by
listening-in
during
recording
(monitoring)
either
through
headphones
(adjust
the
volume
and
bal-
ance
with
the
controls
@)
and
@)
or
through
an
amplifier
connected
to
monitor
socket
9:
in
this
case,
the
volume
etc.
is
adjusted
on
the
amplifier.
@
Set
stereo/mono
switch
to
‘stereo’
when
re-
cording
from
one
stereo
or
two
mono
micropho-
nes
and
to
‘mono’
when
recording
from
one
mono
microphone.
This
switch
is
not
operative
during
playback.
@
For
suppression
of
the
annoying
whistle
tone
which
may
occur
when
being
closely
located
to
the
transmitter
during
stereo
radio
transmissions,
this
recorder
is
provided
with
a
pilot-tone
suppression
filter.
When
recording
such
programmes,
you
can
switch
on
this
filter
with
switch
@).
This
filter
is
not
operative
during
playback.
@
During
the
making
of
microphone
recordings,
no
apparatus
must
be
connected
to
socket
Similarly,
during
the
making
of
other
than
mi-
crophone
recordings,
no
microphones
must
be
connected.
To
prevent
unwanted
noise
being
recorded,
sockets
not
in
use
should
not
be
touched
during
recording.
