M-460 / M-440 Super Grounding plate

M-460 / M-440 Super Grounding Plate

Large area, high conductivity, ultra-long lifespan — fast, stable, and environmentally safe grounding for ultimate power performance.

Why Grounding Matters

Effective grounding is essential not only for maintaining a zero potential difference, but also for eliminating internal and external electromagnetic noise and protecting equipment from surge damage. Traditional grounding methods—such as buried copper rods or plates—are prone to oxidation and corrosion due to soil acidity and moisture, degrading long-term performance.

To overcome these limitations, Monitor Acoustics has developed the fourth-generation M-460 and M-440 Super Grounding Plates, utilizing a proprietary non-metallic composite conductive material that surpasses copper in durability, conductivity, and environmental compatibility.

Advanced Composite Formula

The core of the M-Series grounding plate is built from an exclusive blend of:

• Carbon crystals

• Naturally conductive minerals

• Hydrated silicate compounds (water-glass silicates)

This composite is high-pressure molded into solid plates using a process that ensures structural integrity, anti-corrosion, and high conductivity. The mineral-based, non-toxic material is environmentally friendly, with no risk of groundwater contamination, and offers a lifespan of up to 100 years—far exceeding traditional metal-based systems.

Superior Grounding Performance

The plate's cementitious matrix features excellent electrolyte absorption and release properties, facilitating constant hydration and ion exchange with surrounding soil. This chemical interaction gradually converts soil ions to an alkaline state, significantly lowering contact resistance and enhancing the current dissipation capacity of the grounding system.

Key Benefits

• Ultra-low resistance between grounding plate and soil

• Rapid discharge of potential differences and static energy

• High surge protection and EMI suppression

• Maintains a stable "0V" ground reference

• Resistant to oxidation, weather, and pressure

• Excellent soil bonding properties for long-term consistency

Whether you're building a new system or upgrading an existing power infrastructure, Monitor Acoustics Super Grounding Plates deliver unmatched reliability, safety, and grounding efficiency—designed for high-performance audio, critical industrial systems, or residential applications requiring stable, noise-free power.
