What is the best device to check to speed accuracy on the prime signature 21 without buying the ADS?
The turntable was setup using laser but how I check the speed accuracy on my own? What should I buy? Also does it matter where the belt is rotating on the platter? In the middle? I think the dealer said it will settle on its own.
Do you want to control the speed of the platter or measure the speed of the platter? If the later, a strobe disc is the least expensive option. If you want to control the speed with a higher degree and less variance, a motor controller is the best option.
