Denon DR-M22 - Bias Adjustment; Monitor Switch

The
tape
select
indicators—NORMAL,
CrOs,
and
METAL—provide
guidelines
for
the
maximum
allowable
recording
levels
for
each
tape
type.
Adjust
the
INPUT
LEVEL
controls
while
checking
the
FL
PEAK
METER.
Guideline for maximum recording level
+1 dB levels on peaks
+3 dB levels on peaks
Note:
Optimum
recording
levels
can
differ
depending
on
program
sources
or
the
type
of
tape
used.
Make
trial
recordings
using
the
simultaneous
monitoring.
Refer
to

Metal tape +5 dB levels on peaks
‘mg Meter reading difference between L and R channels
The
left
and
right
channel
readings
of
the
FL
PEAK
METER
can
differ
due
to
variations
in
input
signal
levels.
In
such
cases,
adjust
the
individual
channels
of
the
INPUT

controls
until
identical
meter
readings
are
obtained
for
both
channels.
RECORDING BIAS ADJUSTMENT
For
best
recording
results,
monitoring
during
the
recording
process
and
comparing
various
recordings
using
your
own
judgement
are
essential.
The
DR-M22
is
equipped
with
a
bias
fine
adjustment
control
to
assist
you
in
setting
the
proper
bias
for
different
types
and
brands
of
recording
tape.
At
the
center-stop
position,
the
deck
is
set
for
a
reference
bias
level
for
CrOz
and
NORMAL
tapes.
If
the
resulting
recording
in
this
position
has
too
much
or
too
little
high
frequency
content,
varying
the
bias
fine
adjustment
contro!
can
be
useful
to
achieve
better
results.
If
the
high
frequencies
(treble
sounds)
are
to
be
boosted,
turn
the
bias
contro!
counterclock-
wise
to
decrease
bias
current.
If
distortion
is
of
more
concern
than
high
frequency
response,
turn
the
control
clockwise
to
increase
bias
current.
By
the
use
of
this
control,
you
can
record
tapes
with
response
that
matches
your
personal
listening
tastes.
