Pitch
control (turntable

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 betow
the threshold of human perception. (See
Fig.

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