Stroboscope Testrecord
The Clearaudio STROBOSCOPE TESTRECORD satisfies the highest demands for an
exact speed adjustment for turntables.
Dramatic sound improvements can be reached only with exact calibrated speeds.
- Optimal adjustment for turntables -
To adjust the exact speed, please choose the side for 50 / 60 Hz, or the other side for the
use with the speed light first.
If you choose the side without the speed light source, you can
use the regular light source for the installation, either 50 Hz
(outer scales) or 60 Hz.
The scales are graduated in three different reading options: 33,3
Hz, 45 Hz and 78 Hz (starting from the outer diameter).
Please place the stroboscope disc on your turntable platter and start the engine of your
turntable. The big advantage of the Clearaudio strobe disc is, that you can place your
cartridge onto the strobe record, while measuring the speed, as there are grooves provided
on the disc. This means, for the first time a real time speed analysis is possible under
realistic circumstances.
If you have the impression that the horizontal lines move on the scale, you should set or
readjust the speed of the motor again.
- If the lines move clockwise, the speed is too fast.
- If the lines move counter clockwise, the motor speed is too slow.
Please correct the speed on your motor or turntable until you have the impression that the
lines stopped moving. After that you have reached the exact speed, you can enjoy the full
potential of your vinyl collection again.
