The Ground (or Earth) connection is the absolute reference for all of your vital system voltages. As such, it has to be as silent and stable as possible.
The ultimate way to eliminate ground-line noise is to utilize clean, dedicated earth, which is fraught with myriad safety and regulatory issues.
The GroundMaster eliminates all of the problems typically associated with the connection of additional earthing rods (or other buried metalwork) into an audio and/or audio-visual system, and allows for a simple, economical, and substantial upgrade to your listening and viewing experience.
Almost every modern electrical item is equipped with a high-frequency switching power supply that uses its Earth connection as a dumping ground for the interference they generate. With substations often serving hundreds of houses, your HiFi Earth/Ground connection could be connected to thousands of Earth Line polluting appliances.
With the Puritan GroundMaster (used in conjunction with an additional ground rod), offending noise and disturbance frequencies are identified and channeled through a low-impedance route to the ground, ensuring their elimination.

For the past 50 years houses have normally been connected using the Protective Multiple Earth (PME) system, whereby the Neutral Line is bonded to Earth at the substation and at other points along the way and with Neutral and Earth circuits separated at the point of entry to the building. This style of installation provides the greatest dangers if using additional ground rods without connecting though the GroundMaster whilst other styles of household Earth connection will still benefit greatly with increased safety and performance by using the GroundMaster.
A single core cable to run from the ground rod to the GroundMaster will be required. Smaller diameter cables are easier to handle whilst fatter cables offer lower resistance over length and because of this can provide performance gains. (The overall resistance of a 10 metre length of 2.5mm2 cable would be 0.07Ω , 10.0mm2 0.02Ω.)
Depending on the type of soil, further improvements can be achieved by using additional ground rods linked together at minimum 1.2M spacing. Remember also that ground rods rely on moisture to link electrically to the Earth, in dry spells watering the area will elevate performance.
Further performance gains can be achieved using moisture retaining clay or conductive aggregates to surround the ground rods e.g. Bentonite and Marconite.
Suitable ground rods are available from many online sources.The clamp to attach the cable (Part No. 98752). 10M of 10mm2 green and yellow one core cable (Part No. 4048T) or 100M of 2.5mm2 (Part No. 4752T)
