REC.
BIAS
Generally,
for
recording
on
regular
tapes
(Scotch
150;
BASF
LP-35;
Agfa
PE-31;
SONY
S-100;
etc.), the
REC
BIAS
should
be
set
to
NORMAL.
When
recording
high
performance
tapes
(Scotch
203;
BASF-
LP-35LH;
Agla
PB-36;
SONY
SLH-550;
etc')
which
require
a larger
bias
tlian
regular
types,
always
set the
REC'
BIIS
switch
to
HIGH.
This
will
allow
taking
complete
advantage
of all
the merits
of a
high
perfomance
tape
at
recording
wide
range,
high SN
ratio,
large
output,
low
distortion
and
witie
dynamic
range
NOTE:
Not
only
will
the
l'righ
notes
be exaggerated
and
sound
balance
destroyed
when a
recording
is made
on a
high
performance
tape at
the
NOR\IAL
setting
of the
switch
but distortion
will increase
and tire
sound
will
be unnatural.
Also,
in
the opposite
situation--if
a regular
tape is
recorded
with
the
switch
remaining
in
the
HIGH
position,
balance
will be
destroyed
with lack
of
high
notes,
and
moreover,
the
recording
level
rvill
be low
and
sound
unnatural'
EXPERT
MONITORING
AT
RECORDTNG
ON
LOW
NOISE
TAPE
Although
therc
will be no
difference
in sound
level,
when

there
will be
difference
in
sound
volume
(including
meter
level difl'erence)
between
the
source
ancl
tape
wl.ren using
low noise
tape
(sound volume
will
be lower
on the
TAPE
position
but
this
is due
to
difference
in tape
sensitivity).
If
you wish
to compare
sound
between
the
source
and
tape
at
the same
sound
1evel,
advance
the OUTPUT
knob
to match
sound
level with
that
from
the source
