Speed Calibration - Oracle Audio Origine MkII Owner's Manual

Speed calibration

The precise setting of the rotation speed of the platter is fundamental in order to ensure that the
harmonic structure of the musical notes be reproduced with accuracy! The most precise method to calibrate the
platter rotation speed is to use of the supplied Calibrator disc to locate the desired motor position with respect to
the plinth..
Place your Calibrator disc on the platter and use an incandescent light source to ensure that the strobing
effect of the Calibrator disc is easily and clearly visible. (Light sources like the Sun or battery powered flashlights
will not work).
Note: The outer set of two strobe marks is for 60Hz and the inner set of two strobe marks is for 50Hz.
The inner band of strobe bars is for 33rpm while the outside band is for 45 rpm.
-
Turn on the motor at 33
Calibrator disc that correspond to 60Hz.
- Moving the motor closer to the plinth will cause the speed to increase very slightly. Moving it away
from the plinth will cause the speed to slow down slightly.
-
Position the motor where the strobe marks come to a standstill.
-
Note: If you have never used a Calibrator disc before we recommend that you learn more about it with
the help of our Calibrator disc owner's manual available on our website's product page for the
Calibrator disc.
