Revolutionise Your System with the Telos Audio Grounding Noise Reducer
Achieve cleaner, more transparent sound with the Telos Audio Grounding Noise Reducer (GNR), an advanced active grounding system designed to eliminate ground noise and interference that degrade audio and video performance.
Unlike conventional passive grounding boxes, the Telos GNR actively generates a precise ground reference voltage, stabilising your entire system and preventing noise contamination from home appliances, computers, and switching power supplies.
By providing an independent, ultra-low noise ground reference, the GNR ensures a consistent electrical foundation for your A/V components. This results in a lower noise floor, improved clarity, and enhanced separation between instruments, allowing music to be heard with greater detail, depth, and realism.
Why Telos GNR is Superior to Passive Grounding Boxes
Traditional passive grounding solutions rely on copper plates, rods, or minerals, which degrade over time and fail to address fluctuating voltage levels. The Telos GNR features a built-in CPU that continuously calculates and generates a high-precision ground voltage, ensuring a stable, interference-free reference point for all connected components.
What You'll Experience:
- Dramatic noise reduction for blacker backgrounds and higher resolution
- Greater depth, separation, and imaging, revealing intricate musical details
- Improved tonal accuracy and dynamic range for a more natural, immersive sound
Effortless Integration & Custom Setup
The Telos GNR includes six high-quality ground cables for easy connectivity. Simply ground your equipment via an unused RCA, XLR, USB, HDMI input, or a spade under a chassis screw. Experimenting with different grounding points can further refine your system’s sound, maximising performance.
Key Features:
- Active CPU-Controlled Grounding: Provides a precise, ultra-low-noise ground reference
- Independent Grounding Circuit: Isolates A/V components from household electrical noise
- High-Purity Ground Wires: Ensures uniform impedance across connected equipment
- Expandable Configuration: Supports multiple components for full-system grounding
- Seamless Setup: Compatible with RCA, XLR, USB, HDMI, and chassis grounding points

Introduction
Grounding facility has always been there for the sole purpose of safety.
For example, shock hazard prevention, lightning protection, noise shielding and other functions. In an audio setup, the effectiveness of the grounding facility has an immediate impact on the background noise.
This translates to poor sound quality and greatly worsens the listening experience.
Present Situation
It is almost impossible to get satisfactory grounding facility, let alone one that meets the requirements for audio use.Most of the time, they only adhere to the minimum safety requirements.
The common ones have the Neutral wire and the Ground wire connected together, or there is no Ground on the receptacles, leaving the Ground wire unconnected. This allows noise from the home appliances to pollute the Neutral wire, hence, causing interference.
Electrical appliances like inverter air conditioner and those with switching power supplies, like computer, generate the highest level of interference. When the electrical reference point is polluted with noise, it could get into the signal path and you could hear it as noise. The noise could potentially enter the digital circuit and cause bit error.
The Pros and Cons of Passive Audio Grade Grounding Box
Passive grounding boxes out there are made using materials with good conductivity like copper plates, copper rods, copper mesh, mineral powder or some composite substance.
The good point about the passive, simulated Ground is that it is very easy to make. In fact, most of them can be made easily. The challenge is that passive grounding could only alleviate voltage change.
They are not able to provide near Ground reference voltage. Hence, it is not able to quickly stabilize the fluctuating potential difference between the audio equipment.
This could be liken as ships on the ocean, always floating, the Ground reference is never stable enough. At the same time, the properties of the minerals or electrolyte will change over time and need to be serviced on a regular basis.
This includes material replacement, realignment, or replenishing of the electrolyte before the effectiveness could be restored again.
Telos GNR Active Grounding Box
Due to the above limitations, TELOS brings new meaning to grounding implementation.
And this has been proven to be the most elegant way for any audio setup. TELOS technical team analyzes audio equipment from a unique perspective.
Every audio equipment uses power transformer in order to operate at the correct internal voltage. Hence, each equipment is said to have the primary side and secondary side. The primary side is from the power receptacle, all the way to the input of the transformer.
The secondary side is from the output of the transformer to the circuit board. The audio circuitry remains within the secondary side.
Telos technical team proposes the use of CPU within the GNR to calculate and generate high precision Ground reference voltage.
Grounding is achieved by connecting the audio equipment to the binding posts of Telos GNR that carry the Ground reference voltage. By doing so, GNR is able to truly correct the Ground reference point for the equipment chassis, audio circuitry and the Ground connection.
Using the same analogy as a high precision digital clock, GNR generates low distortion Ground reference voltage, giving each equipment a consistent reference point.
When the audio setup is operating on a singular Ground potential, the signal transmission becomes least impeded, avoiding any transmission loss due to polarity mismatch and bit error.
Therefore, truly achieving the best transmission possible.
