There always seems to be an issue when somebody tries to ground audio gear. It’s a major source of distortion and humming.
Something called a “ground loop” can happen when the chassis connections of different equipment pieces are not all at the same ground voltage.
Your turntable is no exception to this and must be correctly grounded to the amplifier to avoid noise and get the best performance from your system.
Here are the steps and some tips on how to ground a record player:
Step 1: Cut The Power
Before you ever do anything that has to do with wires and electricity, turn off the power. When it comes to record players, this precaution can prevent loud noises that can damage your ears and the speakers as you make the connections.
This also lowers and eliminates the risk of electrocution.
Step 2: Locate The Grounding Wire
Check for your turntables grounding wire. Generally, it will be connected to the underside of the record player chassis. It will have a copper spade connector that is not connected.
Most of the grounding wires on these machines are going to be green, but it’s possible for them to have another color.
Step 3: Find The Grounding Terminal
You will locate the grounding terminal behind the unit, and it will be marked “ground.” This can be a metal post with crossed lines, or it can be a screw terminal. You will then want to loosen the ground terminal.
Step 4: Make Sure There’s Enough Wire
You need to ensure there is enough grounding wire to reach the terminal. You might need to relocate your equipment to make up for the lack in the distance.
Step 5: Connect
Connect the ground wire spade to the grounding terminal and make the connection tight.
Step 6: Turn the power on, and your system is ready.
