Product Description

Telos Grounding Noise Reducer


The purpose of electrical grounding has always been for safety. For example, shock hazard prevention, lightning protection, noise reduction and other functions.

In an audio setup, the effectiveness of the ground has an immediate impact on the noise floor. Poor grounding translates to poor sound quality and greatly worsens the listening experience.

Enter the Telos Grounding Noise Reducer

The Telos GNR is an active grounding device, making use of proprietary quantum technology and a processor that creates a reference 0 volt ground for each component connected to it. It is separated into three sections. On the left and right hand sides are the Telos Quantum Noise Resonator modules. The middle section houses the CPU that is the core technology of the GNR. There are six (6) binding posts located on the rear of the unit for connecting the Telos grounding cables that connect to your audio components. Each connected component ground is “cleansed” by the two (2) Quantum Noise Resonator modules, and drains away noise via the active reference ground.


Grounding & Noise in Today's Environment

In today's electrical environments, It is nearly impossible to attain satisfactory grounding, let alone  grounding that meets the requirements for optimal performance of audio components. Most of the time, manufacturers only adhere to the minimum safety requirements. The common practice is to have the Neutral wire and the Ground wire tied 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 air conditioners and those with switching power supplies, like computers, 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 a Passive Audio Grade Grounding Box

Passive grounding boxes are made with highly conductive materials like copper plates, copper rods, copper mesh, mineral powder etc. The challenge is that passive grounding can only alleviate voltage changes. Passive grounding boxes are not able to provide near ground reference voltage. Hence, they are not able to quickly stabilize the fluctuating ground voltage potential difference between audio components.

In our opinion, the GNR is not a replacement for passive ground boxes, but an enhancer.

TELOS GNR Active Grounding Box

The  TELOS active grounding box brings new meaning to grounding implementation. The active method has been proven to be the most elegant way to address grounding issues for audio components.

The TELOS technical team analyzes audio equipment from a unique perspective. Every audio component uses a power transformer in order to operate at the correct internal voltage. Hence, each component is said to have a 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.

The TELOS Grounding Noise Reducer makes use of a CPU inside to calculate and generate a very precise 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, The Telos Grounding Noise Reducer generates a low distortion ground reference voltage, giving each component a consistent reference point. When the audio setup is operating on a singular ground potential, the signal transmission becomes less hindered, avoiding any transmission loss due to polarity mismatch and bit error. Therefore, truly achieving the best transmission possible. 

The TELOS GNR Active Grounding Box comes with Ground cables of the same materials. Thus each component is receiving the same grounding impedance potential, this greatly reduces the likelihood of coloration or loss of resolution.

By having an isolated Ground for your audio setup, the effect is as beneficial as having a dedicated power line. Through the GNR generated Ground potential serving only your audio setup, noise will be totally isolated.


The CPU inside GNR Needs the ground as a reference point in order to operate.
