There's a low buzz (humming or buzzing sound) while a record is playing. Why?

Check the following:

1. Is the ground wire (signal GND) between the turntable and the connected device unplugged? Connect the ground wire correctly. For details, refer to [Connections] in the Instruction Manual.

2. Are any electrical devices such as fluorescent lights, or their power cords, located near the turntable? Place the power cord of the light or other device as far away as possible.
