This important element is a loop of rubber or different elastomeric materials that connects the motor to the turntable platter, enabling the platter to rotate at a constant velocity. A correctly functioning one ensures correct playback velocity, minimizing wow and flutter, that are velocity fluctuations that distort the sound. For example, a belt particularly designed for a 33 1/3 RPM turntable shall be totally different in measurement and elasticity than one for a forty five RPM turntable or a 78 RPM turntable.
Correct rotational velocity is key for devoted sound copy. This element performs an important position in sustaining this accuracy. Traditionally, numerous supplies have been employed, together with rubber, neoprene, and different artificial elastomers, every with particular properties affecting efficiency and longevity. Selecting the proper one ensures optimum playback high quality and minimizes put on on the turntable’s motor and different elements. A stretched, deteriorated, or incorrectly sized one can result in inconsistent velocity, slippage, and finally, broken information.
