Recording
with
High Tone
Quality
Bias-adjustment
control
Because
the dynamic
range
of
cassette
tape is
narrower than the
dynamic
range of a digital
source,
the
recording will be
too noisy
if
the recording
level setting
is too low, and,
conversely,
the recorded
sound
will be distorted
if the setting
is too high.
It was
for this reason
that it has always
been
recommended that
the signals
to
be
recorded be
first
(before
recording)
input to the
cassette
deck
and the
recording
level then be set while
watching
the level meter, but, for former conventional
level heter
equipped
with the
peak-hold
function, it was necessary to re-adiust and
input
the signals again
if the level setting
was
too
high
or
too low.
This unit,
however,
is equipped
with the
APRS: Advanced
Precise Recording-level
System,
which
holds and displays
the
maximum
peak
of the
input
signal
level,
so
that once
the
peak
level
of
the source
is held,
there is
no necessity to
re-input the source
signals, and
the optimum
recording level can
be set.
oThe
APRS
function can
be used only
during the
recording-
standby
mode.
