Depending
on
the
type
of
tape
and
the
brand
used,
cassette
tapes
are
characterized
by
individual
variations
in
sensitivity
differences
(high
and
low
recording
levels)
and
frequency
responses
(particu-
larly
in
the
high
range).
In
addition,
the
recording
and
playback
levels
differ
when
recording
is
done
using
a
noise
reduction
system
so
that
the
sound
quality
is
sometimes
impaired.
To
deal
with
these
problems,
this
unit
comes
with
a
calibration
function
which
takes
the
form
of
bias
adjustment
and
is
based
on
a
test
oscillator.
The
tape’s
performance
can
therefore
be
given
full
rein
by
setting
the
optimum
bias
value
and
compensating
for
the
sensitivity
in
accordance
with
the
recording
characteristics
of
the
tape
while
observing
the
input
level
display.
™
Before
proceeding
with
calibration
*Switch
to
the
CD
direct
mode
when
recording
directly
from
the
CD
player.
