If you use the Speed Light (AC039) you can reach an even higher or
more accurate adjustment, completely independent of the power
line or frequency of your country. As well, the 300 Hz calibrated
light, used as an external light source is completely independent
from possible power line fluctuations, which could influence the
result by regular light. The 300 Hz of the “Speed Light” are
generated by a stabilized quartz oscillator and permit a very exact
adjustment.
Please put the STROBOSCOPE TESTRECORD with the fine lines
upward on your turntable. Here you also have the possibility to choose between two
different speeds. With the outside scale you can detect the speed of 33 Hz and with the
inside scale you can detect the speed of 45 Hz. Again, 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.
Press the button of the speed light source and place it parallel over to the scale and adjust
the motor or turntable speed until the horizontal lines do not move anymore.
- Tip -
As more accurate your turntable speed is adjusted, as better the overall sonic appearance of
the record playback will be !
It is mandatory to check the speed several times through out the year, to ensure that other
influences are not minimizing the sound quality.
