If your turntable is humming when it is grounded, it is likely due to a ground loop. A ground loop is a condition that occurs when there are two or more ground paths that are not electrically connected. This can create a loop of current that can cause humming or buzzing noises.
There are a few things that can cause a ground loop. One possibility is that the turntable is not properly grounded. If the turntable is not grounded properly, it can create a ground loop between the turntable and the speakers.
Another possibility is that there is another electrical device in the same room that is not properly grounded. This can create a ground loop between the turntable and the other device.
Finally, it’s also possible that the power outlet that the turntable is plugged into is not properly grounded. If the power outlet is not grounded properly, it can create a ground loop between the turntable and the outlet.
If you’re experiencing humming or buzzing noises on your turntable when it is grounded, there are a few things you can do to try to fix it. First, you can try moving the turntable to a different power outlet. If that doesn’t work, you can try using a ground loop isolator.
A ground loop isolator is a device that can help to break the ground loop and prevent the humming or buzzing noises. You can find ground loop isolators at most electronics stores.
Finally, you can also try contacting the manufacturer of your turntable. They may be able to provide you with additional troubleshooting tips or instructions on how to properly ground your turntable.
Here are some tips to help prevent turntable hum when grounded:
- Use a properly grounded power outlet: Make sure that the power outlet that the turntable is plugged into is properly grounded.

By following these tips, you can help to keep your turntable in good condition and prevent humming or buzzing noises when it is grounded.
