Foundation Ground Core

A modular active-grounding core — independent digital and analog routing

Foundation Series

Design Highlights

Providing audio systems with fundamental power and grounding that reaches reference-level performance

Chassis classic re-creation

Using GNR / QRC size standards to achieve the best balance between module compatibility and system integration.

Appearance upgrade

Combining the design DNA of the Master series and Supreme series, reinterpreting the smile. Curves present an industrial design that is more recognizable and elegant.

Performance trickle-down

Telos uses self-developed chips and active module cores to implement the Master series technology, achieving an entry-level to high-end product strategy.

Officially Launched

Legendary Technology Evolved

In 2025, Telos will grandly launch the new Foundation series, based on the classic GNR / QRC chassis, inheriting the flagship specifications and parameters of the Earth Grounding Master series created in the past six years, achieving up to 40% of the flagship performance in a more compact size, and redefining the core value of active grounding and power tuning.

With the global debut of the Foundation series, Telos once again sets a new benchmark for high-end audio; it is more than a foundation — it is Telos' reimagining of, and tribute to, the future core of a system.

40%: Flagship performance
6 yrs: R&D heritage

Foundation Ground Core

Grounding Technology Evolved

Telos' newly released Foundation Ground Core has achieved a technological breakthrough based on the mature active grounding architecture; you may use one side for Digital equipment, and another side for Analog.

Terminals 1, 2, and 3 are recommended for connecting digital devices, while terminals 4, 5, and 6 are recommended for connecting analog devices. Or you can simply use two Foundation Ground Core to separate digital and analog equipments.

Digital can be CD player, Music Server, DAC

Analog can be Turntable, Preamp, Power AMP

For Pro Audio Tuning

Triple Frequency Switching

Three new switchable correction frequency modules ( 7.83Hz / 432Hz / 528Hz ) are added to meet the advanced needs of audio players for sound tonality.

7.83Hz

Enhances low frequencies

432Hz

Enhances mid-range vocals

528Hz

Enhances high frequencies and spatial details

No signal：No operating frequency.

Personalized High-Fidelity

Modular design provides flexible matching and upgrade space, providing a customized grounding solution for your system.

Combined with Telos' consistent low impedance grounding technology, the sound is quieter, the soundstage is wider, and the details are richer.

A Significant Advancement In

Active Grounding Technology

Frequency Correction Circuit

528Hz golden frequency tuning, Enhance the emotional expression of music, creating a sound that is warmer and more fluid.

CPU Voltage Regulation

Enhances stability by 40% and effectively suppresses voltage fluctuations to guarantee the long-term reliable operation of the Active Grounding circuit.

Tuning Technology

Utilizing a distinctive solder formula to enhance conductivity, create a more natural sound and further minimize the distortion resulting from ground noise.

Grounding Circuit Elements

Lower output impedance, enhance current output capacity, and ensure grounding is more stable and efficient.

GNR Noise Resistance

Enhance the clarity of the audio signal, create a quieter and more transparent sound field, and allow the musical details to be more distinctly perceived.
