How To Ground A Turntable Record Player (And How To Determine If You Need To)

Grounding your turntable probably won’t make an immediate difference, but it’s an easy thing to do, so why not do it? so glad you did. At some point, your recorder may start humming. This is usually due to what is known as a “ground loop”. The way to fix the ground loop is to ground your turntable. Even if you don’t have this problem right now, it’s not uncommon for it to appear at some point. Future.

Why ground a turntable?

Contents

The short answer is: enjoy a noise-free music experience from your recorder. That humming can be annoying, but whether you’ve been using your turntable for a while or just started using it, the humming noise is something you can easily avoid. And anything made of live metal carries a high risk of the wires coming into contact with a highly conductive metal housing.Electric current generates sparksThis causes a ground loop. On higher end devices, this can cause vibrations when you touch it. But for turntables, the result of a loop on the ground is an annoying noise. It will happen more intensely if your turntable is processing signals from a sensitive cassette.

Do you have to ground your turntable?

The best way to answer this question is to ask another: do you want the recordings you play on your turntable to be pure and crisp, not interrupted by a horrible humming that develops into an annoying sound when you turn up the volume? If you answered “yes”, then you need to ground your turntable. The type of turntable doesn’t matter. Whether you have a belt or a direct-drive turntable, you may encounter a ground loop at some point. The only thing that makes a difference as to whether or not you really have to ground your turntable is if you have an amplifier with a phono preamp built in. More scientifically speaking, it is the result of the chassis connections not having the same potential or grounding voltage. Not only will this help reduce or even eliminate noise, but it will also help your turntable reach its full potential, giving you the best quality sound it can produce. or not really the humming is caused by the ground loop. the ground loop humming is one of two you can hear. The ground loop noise is 120 hertz, while the other is 60 hertz. You’ll have to rule out 60 hertz hum to see if it’s time to get your hands dirty and grind your turntable.A hum with a certain hertzYou’re probably thinking this sounds too scientific and only an expert can tell the difference between the two noises. That is not the situation. Any untrained ear can clearly hear the difference Think of the 60 hertz humming like an elephant rolling around a savanna, low and slow, and think of the 120 hertz noise like a bee The squirrel is angry. The 120 hertz hum is much higher and more aggressive than the 60 hertz hum, which is low and mellow. If you are still not sure, this page can help you. Does the noise follow? Does it get louder when the volume is up and quieter when the volume is down? Next, select different inputs and note if the others still make noise. If the volume changes and the humming doesn’t change the volume when you adjust the volume knob, your problem is grounding. the input(s) in question. To indicate once and for all if the noise is caused by the ground loop, disconnect all your inputs. If the humming stops completely, you’ve got a ground loop. What did you find? Is your noise caused by a grounding loop? Then learn how to fix it and hear your music the way you deserve it. Read more: How to keep the canopy from blowing away.

Materials needed

  • Ground wire attached to turntable
  • Approximately 5 feet (1.5 meters), with well-insulated 18 to 20 gauge twine, if your turntable does not have a ground wire
  • The ground terminal is attached to the amplifier, although there is a workaround if your amplifier does not have a ground terminal
  • Gaffer tape, if your amplifier doesn’t have a ground terminal
  • Needle-nose pliers

Step 1: Turn off the power

You don’t want to end up with a case of tinnitus (that’s never going to happen regardless, so don’t worry), so turn off the amplifier and turntable. This way there isn’t any loud noise coming out when you connect what you need. The risk of shock is inherently low, but turning off the amplifier and turntable completely eliminates this risk.

Step 2: Find the ground wire

Typically, it will be attached to the underside of the turntable’s metal frame. You’ll notice the lead by an unconnected copper connector, usually a flat piece of metal with a carved u shape if it won’t be the standard color for your ground wire, but most are blue. leaf. If you have a more modern turntable and are having a hard time finding the ground wire, check underneath the chassis – it could be wrapped with a twist tie. If yes, remove the wire, if you can’t find it, you will have to manufacture the ground wire yourself. This is where the 18 to 20 wire is 5 feet or 1.5 meters wide. Using needle nose pliers, strip about 6 to 8 mm of insulation from both ends. More steps to follow Read more: How to keep the canopy from blowing

Step 3: Find the ground terminal

This will be on the back of your amplifier or terminal. If it’s there, you shouldn’t miss it, as it’s clearly marked “Ground”. It will look one of two ways – either a metal post with a slotted shaft, or it will be a factory screw terminal. Once you have found the grounding terminal, loosen it, you can see that there is no grounding terminal. Don’t worry, you can still ground your turntable with just the ground cable and the actual body of the amplifier.

Step 4: Check the measurements

Now that you’ve found the ground wire and its proper terminal, make sure the wire can actually reach the terminal. If that’s not possible, move your devices closer together. Read more: How to keep the canopy from blowing away.

Step 5: Create a connection

Remember how to go back to step one, when you turned off your turntable and amplifier? Well, now is the time for that to matter. Take the copper pyramid terminal of the ground wire and place it on the ground terminal. Then tighten the connection, but do not over tighten or you may break the connector. are making your own ground wire, take a stripped end and attach it to the amplifier’s frame, preferably to a screw, not to the speaker connector. Then take the other end of the wire and attach it to the frame of the turntable, also with a screw. This serves the same purpose as the ground wire attached to the ground terminal, but find the spot that makes the best connection and emits a simple way to check the best location is to touch the top end of the wire. different areas of the turntable’s frame (with the power back on and being careful not to touch any metal with any part of your body).
