Power display indicators
These
are
indicators
which
electronically
show
the
peak
output
level
of
this
unit
with
an
extremely
fast
response
time.
:
These
indicators
can
be
used
to
watch
continuous
signal
changes,
such
as
in
music
signals.
lf
the
impedance
of
the
speaker
systems
is
8
ohms,
the
indicators
show
the
actual
standard
value;
if
the
imped-
ance
is
16
ohms,
the
actual
value
is
one-half
of
that
shown:
and,
if
the
impedance
is
4
ohms,
the
actual
value
is
twice
the
indicated
value.
If
main
and
remote
speaker
systems
are
used
at
the
same
time,
impedance
will
change
according
to
the
following
equation:
Total impedance= Ru Re
Ri + Re
Where: Ri =impedance of main speakers.
R2=impedance of remote speakers
Consequently,
total
impedance
is
4
ohms
if
8-ohm
speakers
are
connected
to
both
the
“MAIN”
and
the
“REMOTE”
terminals.
Note:
In
the

dB=330
W.
lf
the
‘‘X0.1’’
power
display
range
selector@
is
pushed,
0
dB=
33
W;
and,
if
the
‘‘X0.01’’
is
pushed,
0

Power
display
switch
This
switch
is
usedto
turn
the
power
display
indicators@
on
and
off.
Power
display
range
selectors
This
selector
is
used
to
select
the
sensitivity
of
the
power
display
indicators@.
When
the
output
is
small
and
the
illuminated
range
of
the
power
display
indicators
is
small,
push
the
RO
or
‘‘X0.01’’
selector,
so
that
the
indicated
value
will
be,
respectively,
10
or
100
times
the
actual
value.
Safety/program/FM
stereo
indicators
SAFETY:
|
Usually
remains
indicated;
not
illuminated
if
an
abnor-
mal
condition
in
output
circuitry
is
detected.
(If
not
illu-
minated,
refer
to
page
3.)
PROGRAM:
When
the
program
source
is
selected
by
the
input
se-
lector@,
the
one
of
these
indicators
which
corresponds
to
the
selected
program
source
will
also
illuminate.
FM STEREO:
This
indicator
automatically
illuminates
when
an
FM
stereo
broadcast
is
being
received.
(When
the
mode
selector@
is
set
to
‘‘MONO’’
position
the
indication
does
not
illuminate.)
FM multiplex filter selector
Usually
leave
this
selector
set
to
the
“OUT”
position.
Set
it
to
the
‘IN
(REC)’’
position
(—@—m)
if
“beat’’
noise
is
heard
from
the
tape
deck
(when
recording
an
FM
stereo
broadcast
to
a
tape
deck
which
has
low-frequency
recording
bias).
When
set
to
the
‘‘IN
(REC)’’
position,
the
‘beat’
sound
generated
by
the
38-kHz
sub-carrier
signal
of
the
FM
broadcast
and
the
recording
bias
of
the
tape
deck
will
be
eliminated.
€ FM high-blend switch
Set
to
the
‘‘ON’’
position
(dl
-~m)
if
the
noise
in
the
high-
sound
range
is
excessive
when
listening
to
an
FM
stereo
broadcast.
When
this
switch
is
set
to
the
‘‘ON”’
position,
the
noise
in
the
high
range,
which
is
comparatively
more
annoying,
is
mixed
inthe
left
and
right
channels
without
acoustically
disturbing
the
stereo
feeling,
and
the
noise
is
reduced.

Signal-strength
meter
This
meter
shows
the
strength
of
the
antenna
input
level.
The
point
of
best
reception
for
both
FM
and
AM
is
where
the
indication
is
farthest
to
the
right.
f)
FM
center-tuning
meter
|
This
meter
indicates
the
optimum
tuning
point
for
best
reception,
with
least
distortion,
of
stereo
broadcasts.
After
tuning
by
referring
to
the
signal-strength
meter@,
adjust
the
tuned
position
so
that
the
indication
needle
of
this
meter
is
at
the
center
position.
Note
that
this
meter
will
also
indicate
the
center
posi-
tion
when
the
broadcast
is
completely
detuned.

These
selectors
are
used
for
selection
of
the
input
im-
pedance
of
the
‘‘PHONO
1”
and
‘‘PHONO
2”
terminals.
The
‘‘RESISTANCE”’
selector
is
for
selection
of
the
re-
sistance,
and
the
‘‘;CAPACITANCE”’
selector
for
selec-
tion
of
the
capacitance.
In

the
characteristic
of
a

Car-
tridge
‘‘droops’”’
in
the
center,
as
shown
in
the
frgure
below,
and
has
a
resonance
peak
in
the
high-frequency
range.
When
the
load
impedance
(resistance
and
capac-
itance)
is
changed,
it
is
possible
to
change
the
height
and
center
position
(resonance
frequency)
of
this
reson-
ance
peak,
thus
making
delicate
changes
in
the
tone
quality.
Ordinary
use
is
as
described
below,
but
other
settings
can
be
made
for
variation
of
the
