Clearaudio Speed Strobe Test Record + 300Hz Quartz Light
The Clearaudio Strobodisc is a speed test record that allows you to correctly set the speed of your turntable (where fine tuning the speed is possible), complete with laserlight. Simply run the record on your turntable and change the speed while watching the rings and wait for them to change from delayed to constant to set speed.
Use the inner rings to set speed at 45rpm and outer rings to set speed at 33rpm.
A highly effective and very useful tool - correct speed/pitch is essential in getting the best performance from your turntable.
