What is
8 Channel Ground Conditioner is an equipment that I developed for the purpose of eliminating noise in the ground path of the sound system. Ground conditioner is actually already popular with the name Ground Box, I named it Ground Conditioner so that this product has differentiation compared to other similar products, besides that in the field of audio ground conditioner there are two types, active and passive, and the Ground Conditioner that I developed is of the active type.


What is Ground
In the field of electrical ground is a reference point,  a reference point for expressing the voltage value in a place inside  an electronic circuit.
For example, if a point in the circuit is said to have a voltage value of 10V, then it means that the point has a value of voltage 10V relative to ground in the circuit where the point is located


Why ground must be clean
The ground point in a circuit must be completely clean, because if the ground as a reference voltage value is dirty then the voltage value in each point in the circuit where the ground is located will also become dirty.
When two electronic circuits are connected, where one circuit acts as a signal provider and the other is a signal receiver, then the ground point is the point that becomes the common "platform" of these two circuits, and if one or both ground of this circuit is dirty and unstable the voltage value of the electrical signal being sent  will not be stable and eventually will be distorted.
For example from the explanation above is the ground point of the CD Player and Preamp in the home audio system or the ground point of the Head Unit and Processor in the car audio system. If one or both of the ground points in the above pair are dirty, then the signal sent will eventually become distorted and in the end it will become more damaged after being amplified by the preamplifier before sent to the power amplifier.


How does it work
The Ground Conditioner that I developed works by detecting the appearance of noise that is on the tapping point, if there is noise, the Ground Conditioner will send an electric voltage to eliminate the noise.
What is meant by Taping point is the point in the circuit connected to the channel from the ground conditioner.


Active or Pasive
In the world of audio there are two types of ground conditioners, namely active and passive types. The ground conditioner I developed is of the active type. The choice to develop an active type is because active type ground conditioners have the ability to reduce noise on ground in a frequency spectrum that is much wider than what a passive type of ground conditioner can do.
Noise has unlimited frequency spectrum, and passive type of ground conditioner is only able to reduce noise in a limited frequency spectrum, so there are still many missed frequency spectrums that cannot be muted by a passive type of conditioner.


Feature
Besides having the ability to reduce noise in a wider frequency spectrum, the Ground Conditioner that I developed also has other features that other similar products do not have, especially those of the passive type, namely
* Smaller casing dimensions
* More competitive prices
* Has 8 outputs so that it can reach 8 different ground points inside
    audio system, both home or car.
* Available in Home or Car  version


How to connect
GC8's output can be connected to target equipment via certain RCA  or USB cable which has only connection on its ground side, this cable provided together with GC8 unit.   As the entry point on the target unit are unused RCA terminal or USB port.
