Telos Foundation Ground Core

The Telos Foundation Ground Core is a modular active-grounding solution designed to provide audio systems with a cleaner and quieter electrical foundation. Drawing on Telos’ advanced grounding technology, it supports independent digital and analog routing, helping reduce ground noise while improving clarity, soundstage, and detail.

Independent digital and analog grounding

Six grounding terminals provide flexible system configuration, with terminals 1–3 recommended for digital equipment such as CD players, music servers, and DACs, while terminals 4–6 are suited to analog components including turntables, preamps, and power amplifiers. Two Foundation Ground Cores can also be used to completely separate digital and analog grounding.

Triple frequency switching

Three selectable correction frequencies — 7.83Hz, 432Hz, and 528Hz — provide additional system-tuning options. These settings are designed to influence different aspects of the presentation, from low-frequency weight and vocal presence to high-frequency detail and spatial information.

Advanced active-grounding technology

The Foundation Ground Core combines low-impedance grounding circuitry, CPU voltage regulation, and GNR noise-resistance technology to create a more stable and controlled grounding environment. As a result, connected equipment can benefit from a quieter background, improved transparency, and more precise musical detail.

Precision CNC-machined construction

The fully CNC-machined aluminum alloy chassis provides high rigidity and low resonance, while its streamlined design reflects the visual language of Telos’ Master and Supreme series. An anodized finish and refined brushed texture complete its premium appearance.
