and

HEADPHONES
jack
Connect
8-ohm
headphones
for
record
monitoring.
Headphone
level is fixed
in
both record and playback
modes.
(p LINE OUT
level
control
Use
the
control
to
match
the
recorder
output level
with
other
sources connected
to
the
amplifier.
FM
or
Phono mode is recommended
as a
reference
point.
While
adjusting,
do not
change
the
volume control
of the
amplifier.
At
MAX,
the
output level
is
rated 0.775
V
(O
dB) and
at
MlN,
77.5
mV (-2O
dB). The
control does
not
correspond
to
the
VU
meters.
Generally
set this control
at
MAX.
The output level
of
the
REC/PB
jack
is
fixed
at
O.775V without
relation
to the
LINE OUT control.
@
VU
meters
The
meters
show the input
record level
with the
MONITOR
selectors set
at
SOURCE,
and show
the
recorded
level
with
the
selectors
set at TAPE. ln either
case,
O
VU reading corresponds
to
0.775
V.
@
PEAK
level
indicator
The
indicator flashes whenever transient peaks
occur.
Since
it
registers over-modulation
much
more
guickly than
the
VU
meters,
the
impulses
which are
not
shown
in the
meters
can
be avoided by readjusting
the
levels.
Note
that the
PEAK
level indicator illuminates whenever
the
input signal
connected
to the
LINE
lN,
REC/PB
and
MIC jacks
passes
the
point
of
distortion,
but
does
not
indicate
tape
saturation
in
playback.
