What It Does and How To Use: Allows you to accurately adjust and monitor the speed of your turntable from 16.67 - 90 rpm. Designed for use in artificial fluorescent light, the disc's pattern will appear to be static when the turntable's speed is correct (because of the 60Hz frequency). All you need to do is place the disc on your platter, turn on your fluorescent 60Hz light and then adjust your turntables speed control until the lines (see strobe speed disc) on the speed you want stand still.

FSC was founded in 1993 in response to concerns about deforestation. Pitch or tone quality can make a difference with slight difference in speed or when fluctuation of speed occurs. This is why you see our speed strobe goes out to 100th of a percent in RPM tracking. This disc is so accurate that under fluorescent light you can fine tune the speed better than most expensive strobes on the market today! Here is some history on some of the first speeds available for records: 78.26 RPM: Earliest speeds of rotation varied widely, but by 1910 most records were recorded at about 78 to 80 rpm. In 1925, 78.26 rpm was chosen as a standard for motorized phonographs, because it was suitable for most existing records, and was easily achieved using a standard 3600-rpm motor and 46-tooth gear (78.26 = 3600/46). Thus these records became known as 78s (or "seventy-eights"). This term did not come into use until after World War II when a need developed to distinguish the 78 from other newer disc record formats. Earlier they were just called records, or when there was a need to distinguish them from cylinders, disc records. 16.67 RPM: Super slow speed 16 RPM is actually 1/2 the speed of the 33 1/3 RPM speed which is 16.67 or 16 2/3 RPM. Popularity of this slower speed came about as early as the 1930's but really took off in the 1950's with speeches and talking books but not as much music because the fidelity coming from a slower speed is poor.
