- 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.

TELOS GNR Active Grounding Box comes with Ground cables of the same materials. Thus each equipment is having the same grounding impedance characteristics, this greatly reduces the likelihood of coloration. By having an isolated Ground for your audio setup, the effect is as good as having a dedicated power line. Through the GNR generated Ground potential serving only your audio setup, noise will be totally isolated.

Standard WBT-0703 cu pole terminal connector

According to WBT, the signal conductor of the WBT-0703 nextgen™ pole terminal is restricted to as low metal mass as possible consisting of pure copper. This does not simply preserve valuable resources, but also eliminates losses in sound quality owing to the mass storage effect. This effect is unavoidable with larger metal masses and has a measurable influence on signal flow.
