How To Properly Ground Turntable And Phono Preamp
Step 1: Identify The Ground Wire
The first step in properly grounding your turntable and phono preamp is to identify the ground wire. This wire is commonly green, but it may have a different color depending on your specific turntable model.
To access the ground wire, you will need to uncover any wrapping or covering that may be hiding it. Once you have located the ground wire, you can move on to the next step.
Step 2: Turn Off The Power
Before beginning any work on your turntable or phono preamp, it is important to turn off the power to both the player and the amplifier. This will prevent any system malfunctions or dangerous electric shocks from occurring.
Step 3: Manufacture Your Ground Wire
To properly ground your turntable and phono preamp, you will need to manufacture your own ground wire. You can do this by using a 5 feet 18-to-20-gauge stranded wire and stripping about 6 to 8 mm of insulation from both ends using needle-nose pliers.
Next, attach copper spade connectors to the ends of the wires. If you cannot find these connectors, simply strip the end of the wires by about an inch or so.
Step 4: Connect The Ground Wire
Once you have manufactured your ground wire, it’s time to connect it to your turntable and phono preamp. Take one stripped end of the wire and attach it to the chassis of an amplifier, preferably to a screw.
Then, take the other stripped end and attach it to the chassis of the turntable, also to a screw. This will ensure that both components are properly grounded and will prevent any unwanted hum or sound issues.
Step 5: Test Your Setup
After connecting your ground wire, it’s important to test your setup to ensure that everything is working properly. Turn on your player and amplifier and listen for any unwanted hum or sound issues.
If you still experience problems, double-check your connections and make sure that everything is properly grounded. With a little patience and attention to detail, you can ensure that your turntable and phono preamp are properly grounded for optimal sound quality.
Understanding Grounding In Turntables And Phono Preamps
Grounding is an important aspect of any audio setup, especially when it comes to turntables and phono preamps. In general terms, Ground is included as a safety measure to prevent any unwanted electricity from causing harm. All hi-fi boxes are electrically isolated from the metal exterior or chassis to prevent electricity from coming into contact with it.
However, when it comes to turntables and phono preamps, the Ground serves a slightly different purpose. It’s there to avoid a Ground Loop, which can cause extra noise and ultimately impact the sound quality. If you have inter-connected equipment with more than one electrical path to the Ground, a Ground Loop can occur and cause a hum through your speakers.
To avoid this, most turntable designs come with a separate Ground wire attached to the tonearm that can be attached to the amplifier or phono amplifier’s ground screw. This will reduce background hum tremendously and ensure optimal sound quality.
It’s important to note that not all turntables require grounding, especially those with built-in phono preamps. If your turntable has a built-in phono preamp that you use instead of a separate one and you’ve never had sound issues, you may not need to ground it. However, it’s always better to play it safe and ground your turntable if you’re unsure.
The Importance Of Proper Grounding
Proper grounding is crucial for any turntable and phono preamp setup. Without proper grounding, your system is susceptible to unwanted electrical hums and buzzes, which can negatively affect the audio signal.
Grounding your turntable and phono preamp will ensure that any unwanted electricity is safely directed back to your electrical panel, preventing any potential safety hazards. Additionally, proper grounding will prevent ground loops from occurring, which can cause extra noise in your audio signal.
Even if you aren’t currently experiencing any sound issues, it’s important to ground your turntable and phono preamp to prevent future problems. Most turntables come with a grounding wire attached, but if yours doesn’t, you can easily manufacture your own using a 5-foot 18-to-20-gauge stranded wire.
By following the steps outlined above and properly grounding your turntable and phono preamp, you can enjoy optimal sound quality without any unwanted hums or buzzes. So take the time to properly ground your system and enjoy your vinyl collection to the fullest.
