4. Fine adjustment of the motor
1)
The Master Innovation’s motor adjustment is already pre-set at the factory. However, some
small speed deviations can occur during transportation or due to dirt or dust on the sensor
or the sensor ring. Please check the speed before using the turntable for the first time.
To correctly adjust the speed, put the recommended Clearaudio Stroboscope Test Record
onto the platter and refer to the instructions provided in the Stroboscope Test Record user
manual. To check the speed with highest accuracy, you may wish to use the Clearaudio
Speed Light (ref. AC039, available
On the front side of your turntable there are three fine speed adjusters (see image 15
below).
-
Left adjuster = setting 33 1/3 rpm
(near turntable motor)
-
Middle adjuster = setting 45 rpm
-
Right adjuster = setting 78 rpm
(near turntable bearing)
To adjust the turntable speed at 33 1/3 rpm , take the aluminium screwdriver provided and
turn the left adjuster until you have reached the right speed according to the Stroboscope
Test Record (see the relevant user manual).
Turning the adjuster counter clockwise reduces the turntable speed.
Turning the adjuster clockwise increases the turntable speed.
You can also adjust the turntable speed for 45 rpm and 78 rpm in the same way.
Please note:
If the turntable does not reach the correct speed, the sensor or the scale ring could be dirty
or dusty. To clean the sensor, take off the two platters very carefully. Clean the sensor and
the scale ring with a little isopropyl alcohol and a cotton bud. Be very careful to avoid
scratching the sensor or the scale ring.
Should the motor still have speed variations, please contact Clearaudio directly or your
nearest authorized Clearaudio dealer.
Now you are ready to play your vinyl records.
We wish you a great deal of pleasure with your new Master Innovation turntable.
