3. Adjust the speed while playing a record.
The strobe-illuminator/pilot lamp will be lit for illuminating
the strobe dots.
4. While turning the pitch control knobs either to +" side or
"-" side, adjust so that the strobe dots of the turntable
platter look as if they were stationary.
The state under
which the strobe dots seem to be stationary represents the
correct number of revolutions.
"+" direction
This increases the speed of the turntable rotation, and
the strobe
dot
pattern
seems
to
flow
in the
same
direction
as
the rotational
direction
of the turntable
platter.
"—" direction
This
decrease
the
speed
of the
turntable
rotation,
resulting in a state opposite to that in the " + " direction.
Note:
Strobe dot pattern
The strobe-illuminator/pilot
lamp of this unit employs
the commercially available power source. The frequency
of such power source, when
actually measured,
has a
fluctuation of about 0.2%. As such a fluctuation of the
power source affects the strobe illuminator, the strobe
dot pattern also seems to fluctuate to a certain extent.
But the unit is not affected by these fluctuations of the
power source,
since a DC motor
is employed.
In other
words, rotation of the platter will be constant, and slight
shifts in the movement
of the dots simply reflect normal
drift in the power-source frequency.

for automatic
return position (See
Fig. 24.)
(Remove the turntable mat.)
In cases where the tonearm tends to return before playing has
finished.
—Rotate clockwise.
In cases where the tonearm fails to return after the last groove
of the record.
—Rotate counterclockwise.
Features
© New type frequency generator servo control
One of the major secrets behind the razor-sharp accuracy
and superb quality of sound lies in the new type (Frequency
Generator) servo controlled DC motor, and greatly improved
highly reliable IC circuitry. Even the slightest hint of speed
change and drift is corrected immediately.
@ Electronic speed switching
Even
though
this turntable
is belt-driven, gone
is the old
conventional
pulley
type
speed
changing
mechanism.
Speed
switching
in this unit
is fully electronic,
thereby
adding
to the high degree
of mechanical
precision and
reliability.
The advancement
to complete front-panel control
marks a
big step forward in turntable operation, not only because of
the greater convenience,
but also because
of the greater
protection from dust, as the dust cover can stay closed.
