Technics ST-9038 Operating Instructions

ÍD
Power-on/stand-by
switch
Turns
the secondary
power
of this unit on
and
off.
The
unit is in the "stand-by"
condition when th¡s switch is
set to the
"Ó "
position.
This switch controls
the secondary
power
only;
not the
primary power.
Ø
Muting switch/station
selector
(station
selector)
This
switch is used
to
remove
the
"between-station
noise"
characterist¡c of the
FM broadcast band, and to
select the
input signal
strength to the tuner.
"fine":
At this
position,
broadcast
s¡gnals with a
stereo dis-
tortion ratio oÍ O.2Yo or
less can be received.
Broadcasts can
be automatically
tuned by simply
pressing
one of
the automatic-tuning
buttons
@.
At this
pos¡t¡on,
the broadcast signals
indicated
by
(d)
and
(f)
in
the
figure below
would be received.
"standafd":
At
this
pos¡tion,
broadcast s¡gnals
with a stereo dis-
tortion
ratio of
1
l;o
or less can
be
received.
Operation is
the same as
for
the
"fine"
position.
At this
position,
the
broadcast signals
indicated by
(a),
(c), (d),
(f)
and
(g)
in
the figure below
would be re-
ceived.
"off":
At this
position,
all FM broadcast
signals
are received.
Set to this
position
when it is desired to
receive even
weak signals
with a stereo d¡stortion
rat¡o of
more
than 1%.
Note that the
muting funct¡on is off
at this
posit¡on,
and
therefore the volume
control should be
set
to a low
level
for
tuning.
ln addition, although
this is the
"muting off"
position,
the mut¡ng
will function during tuning,
becoming
off
when
the
tuning
is stopped.
@
Mode selector
(mode)
The
mode
selector
is used
to change
reception conditons
and
to select
the
"pink-noise"
generator
used for
adjustment
of
the recording
level,
etc.
"pink
noise":
When set
to this
posit¡on,
"pink noise"
will be emitted
from
the output
terminals
("OUTPUT").
When
a flat frequency
response
¡s indicated by
the
meters,
the
modulation
level
is
set
for507o modulation.
For recording-level
adlustment:
'.
Using
VU
(level)
meters
Adjust
so
that the
indication
needles show
a reading
of
about
-6
VU
(-6
dB).
.
Using
peak-level
meters
Adjust
so that
the
indication
needles
show a
reading
of about
+3
dB.
Because
the
optimum
value
is apt
to vary
according
to the
program
source
and
the
tape deck,
adiustment
of
the recording
level
shor{d
be
made
by taking
such
factors
¡nto
considerat¡on.
"auto":
'
Stereo
broadcasts
will
automatically
be
received
as
stereo,
and
monaural
broadcasts
w¡ll
be leceived
monau rally.
ttmonott:
All broadcasts,
stereo
and
monaural,
will always
be
received
monaurally.
G)
Automatic
high-blend
sw¡tch
(auto
hi-blend)
When
this switch
is set
to the
"on"
position,
the high-
blend
circuitry
will function
automatically,
turning on
and off depending
upon
the strength
of
the input
signal.
The
switch
is
off
when
pressed
inward
(l^¡)'
and
on when
released
outward
(^-r).
The high-blend
circuitry
operates
to reduce
noise,
without
acoustically
disturbing
the
stereo
effect'
by
mixing
the left and
right
high-frequency
range,
where
noise is relatively
more
¡rr¡tat¡ng
to the
ear.
@
Frequency
display
The frequency
being received
is indicated
by
illuminated
digits.
There is,
in addtion,
a stereo
indicator
in the upper
left
part
to indicate
that
a stereo
broadcast
is being
received.
