How To Ground A Rega Turntable – A Step-By-Step Guide

If you’re a vinyl enthusiast, you know that a turntable is only as good as its grounding. Without proper grounding, you may experience annoying hums and other sound quality issues.

If you own a Rega turntable and are wondering how to ground it, you’ve come to the right place. In this article, we’ll cover everything you need to know about grounding your Rega turntable, including why it’s important, how to find the grounding wire, and how to attach it to your amplifier.

So sit back, relax, and get ready to improve your vinyl listening experience.

How To Ground A Rega Turntable

Before we dive into the specifics of grounding a Rega turntable, let’s first understand what grounding is and why it’s important.

Grounding is the process of connecting your turntable and amplifier to the same ground potential. This helps to eliminate any electrical interference that may cause humming or other sound quality issues. Without proper grounding, you may experience a 60-cycle alternating current passing between your turntable and amplifier, resulting in an audible hum.

Now, let’s move on to how to ground a Rega turntable.

The first step is to locate the grounding wire. Rega turntables do not have a separate ground wire, but rather ground the tonearm tube to the phono preamp using the shield of the left channel of the phono interconnect cable. If you’re experiencing any hum, it’s recommended to attach a wire to the outer left RCA plug instead.

If you can’t find a grounding wire at all, you’ll need to manufacture your own. To do this, you’ll need 5 feet or 1.5 meters of 18 to 20 gauge stranded wire. Using needle nose pliers, strip about 6 to 8 mm of insulation from both ends.

Next, you’ll need to attach the grounding wire to your Rega turntable. This can be done by soldering a wire to the case of the motor and connecting it to the base of the tonearm. Then, connect the other end of the wire to the ground post of your phono input.

Alternatively, you can attach a small gauge stranded insulated ground wire from the tonearm to plinth support nut on the underside of the turntable and connect the other end of the wire to the ground lug on your phono preamp.

Once you’ve attached the grounding wire, it’s important to test for any hum or sound quality issues. If you’re still experiencing humming, try repositioning your cables or turntable in case you’re picking up hum from a transformer or mains cable.

Finding The Grounding Wire On Your Rega Turntable

If you have a new Rega turntable, you can find the grounding wire folded underneath the chassis and covered with a twist tie. However, if you’re unable to locate the grounding wire, don’t worry. You can still ground your turntable with just the grounding cable and the actual body of the amplifier.

To find the grounding wire on your Rega turntable, start by searching for a green wire that is typically connected underneath the metal turntable chassis. The color of the grounding wire is not very important to focus on. The grounding wire usually has an unconnected copper spade connector ending.

If you’re still unable to find the grounding wire, you can use an insulated 18-20 gauge stranded wire as an alternative. Ensure that the grounding wire or alternative is long enough to connect to the ground terminal. Otherwise, you’ll need to move both devices closer together to minimize the distance.

Once you’ve located the grounding wire or manufactured your own, follow the steps outlined above to attach it to your Rega turntable and test for any hum or sound quality issues. With proper grounding, you’ll be able to enjoy high-quality audio from your Rega turntable without any interference.

Attaching The Grounding Wire To Your Amplifier

Now that you have grounded your Rega turntable, it’s important to properly attach the grounding wire to your amplifier. The grounding wire should be connected via a single wire that connects the amplifier chassis to a bare metal area of the car’s body.

First, choose an area with bare metal and drill a hole that is large enough for your screw or bolt. If bare metal is not available, you will need to grind down the surface to remove any paint as bare metal is crucial for a proper connection. Clean the surface off by removing any dust or paint. If you used any sort of solvent on that spot, wipe and let dry before attaching anything.

You may be able to find a factory grounding point, screw, or bolt that will work well for your grounding. Make sure the bolt is directly connected to the metal chassis and it does not have any paint, rust, or other residues on it. If it does, grind or sand down the surface to ensure a bare metal contact point.

If you’re unable to find an existing grounding point, you can create one by drilling a hole in the car’s body and attaching a grounding bolt. Just make sure that the location you choose is free from any wiring, brake lines, gas tanks, or other potential hazards.

Once you have your grounding point established, attach the grounding wire from your Rega turntable to the grounding point on your amplifier using a ring terminal connector. Make sure that the connection is tight and secure.

It’s important to note that the grounding wire should be less than 18 inches from the amplifier’s location. This ensures that there is minimal resistance in the ground path and reduces the risk of electrical interference.

By properly attaching the grounding wire to your amplifier, you’ll ensure that your Rega turntable operates smoothly and without any sound quality issues.

Troubleshooting Common Grounding Issues

Even with proper grounding, there may still be some common issues that arise. Here are some troubleshooting tips to help you identify and resolve any grounding problems:

1. Humming or buzzing sound: If you hear a humming or buzzing sound coming from your turntable, it could be a sign of a grounding issue. First, make sure that your turntable is properly grounded by following the steps above. If the problem persists, try moving your turntable away from any potential sources of interference such as transformers or other electronic devices. Additionally, you can try using shielded cables to reduce interference.

2. Static electricity: Static electricity can cause pops and crackles in your audio playback. This can be caused by a lack of grounding or by dry air in your listening environment. To combat this, make sure that your turntable is properly grounded and consider using a humidifier in your listening space.

3. Ground loops: Ground loops occur when there are multiple paths to ground in your audio system, causing a hum or buzz in your audio playback. To fix this issue, try disconnecting any unnecessary audio components that may be causing the ground loop. Additionally, you can use a ground loop isolator to break the loop and eliminate the noise.

By following these troubleshooting tips, you can ensure that your Rega turntable is properly grounded and free from any common grounding issues.

Other Tips For Improving Your Vinyl Listening Experience

While grounding is an important step in improving your vinyl listening experience, there are other tips you can follow to further enhance your enjoyment of your records.

Firstly, make sure that your turntable is placed on a completely flat and sturdy surface. Any vibrations or movement can cause unwanted noise and distortion in your sound. Additionally, keep your speakers off the same surface as your turntable to avoid any feedback loops.

Secondly, it’s important to keep your turntable away from any sources of static. This includes electronics, fabrics, and even certain types of flooring. Static can interfere with the electrical signal from your turntable and cause unwanted noise.

Thirdly, invest in a high-quality turntable support. The vibrations caused by external sources can impact the performance of your turntable and affect the sound quality of your records. A good support will isolate your turntable from these vibrations and provide a stable base for optimal performance.

Finally, make sure that your turntable is properly calibrated. This includes setting the correct tracking force, anti-skate, and cartridge alignment. Improper calibration can cause unnecessary wear on your records and degrade the sound quality.

By following these additional tips, you can ensure that you’re getting the best possible listening experience from your Rega turntable.
