Upon setting the power switch/pitch lock knob to “on”,
the revolutions are changed over to 33-1/3 rmp. at all times.
If the record to be played is other than a 33-1/3 rpm.,
depress the speed select button to suit the phono disc to be
played.
When the power switch/pitch lock knob is set to “pitch
lock”, the pitch control button and speed select button are
locked so as not to be actuated even if the buttons are
accidentally touched during playing. (See Fig. 6.)
Therefore, for selecting the speeds or operating the pitch
control, first set the power switch/pitch lock knob to the
position “on”.

Pitch control (turntable speed fine adjustment).
The Quartz synthesizer system is being employed for the
first time in the world. A high degree of pitch control
accuracy over a wide range (+9.9%) in 0.1% increments can
be obtained with the quartz perfectly locked.
The pitch control is continuously variable up to 9.9%.
The pitch variations which are clearly indicated by the LED
digital indicator provide you with accurate and easy
selection.
The pitch control can be selected in increments of 0.1%
which is below the threshold of human perception. (See
Fig. 9.)

The pitch control also enables you to accurately and
precisely tune musical instruments and by varying the pitch
slightly, to obtain a different musical note from the record.

Another feature of the variable pitch control over a wide
range of +9.9% is that it makes singing along with a melody
easy for a chorus, or for playing a_ record for
accompaniment only. (See Fig. 11.)
