Features:
1. Recording makes the speed of CD player and turntable more stable and accurate.
2. Real-time monitoring of LP speed lets you know it in real time.
3. Test the balance of the turntable / cabinet / speaker so that you can enjoy the best sound quality.

Speed measurement method:

The upper LP dial scale is used to rotate the LP dial labeled 50-33 / 50-45, just like turning the 33 LP disc jukebox to see if the scale is 50 -33. Clearly visible, the normal speed proves to be 33 rpm (approximately),which is incorrect if it is obscure or connected to the line
