Pro-Ject Turntable Earthing Lead (1.2m)

 

Though vinyl is one of our most cherished and enjoyed music platforms, the equipment used to playback records is - by its very nature - prone to issues and problems that can disrupt your experience. One of the most common issues reported to us is mains hum, and though this can be a problem it is almost always not down to a faulty turntable; instead it's because there is not a strong enough 'true' earth in your system.

 

All turntables are prone to attract some level of noise, however, most (like all Pro-Ject record players) are engineered to reduce this tendency as much as possible - so you often only hear it with the amplifier volume on maximum and no record playing. When there is a noise that's audible during normal playback it is often due to poor grounding (even with the supplied ground lead linking the turntable to your phono stage/amplifier), and the problem is typically environmental.

 

There are lots of messy or impractical solutions to try and find an alternative earth-point, but we've found that running an additional earth lead to another grounding point will provide a great solution in most instances. That point could be a dedicated mains plug with just the earth pin connected to the ground lead and both other pins removed, or it could be your system's amplifier, or even a nearby radiator. Each installation is unique, but hopefully these cables can help.

 

The supplied earth lead is approximately 1.2m in length. It is supplied with a fork connector at either end.

 

An additional earth lead should be used when when...

  • You have an earth hum (or buzz) through your system, even when the earth lead is connected between your turntable and phono stage/amplifier. 
  • Your turntable has a carbon fibre tonearm. Carbon fibre is an ideal material for a tonearm, as it is hard and lightweight - however it is not as efficient as a conductor, when compared to other metals, so it can in some instances lead to an insufficient ground.

 

Additional earth leads should not be used when...

  • The noise generated is due electrical interference from the turntable motor or other equipment.
  • The earth noise disappears when you touch the tonearm tube. This more likely indicates an issue with the tonearm wiring. 
  • The earth lead is not connected between your turntable and phono stage/amplifier. In the vast majority of cases, this is a sufficient way to fully ground your turntable.
