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.
