Equipotential bonding
The huge problem in hi-fi
Within the devices, thick ground rails, super-short connections, exact star-shaped arrangements, etc. are sometimes used. Nobody speaks about the masses of the devices and their connection outside the devices. This although the problems with the equipotential bonding of the masses are dramatically greater here (see the measurements of the mass potentials below).
The measurements show us that we can deal with voltages of up to over 100 volts with the mass and that these are strongly dependent on the plug position. When the plug is turned, the voltage changes from approx. 118 volts to approx. 45 volts.
Difference in sound when the power plug is phased out
The voltage differences described above are also used today to assess the correct position of the mains plug. The correct plug position for the sound is the one with the lowest voltage. Phase out is a standard procedure for today's music library when setting up a system.
But what changes in the audio signal? Nothing! The two diagrams show an oscillation gram and a spectrum analysis of a PIONEER N50, once with the correct mains plug position and once with the wrong one. No change can be seen in the signal, although the voltage and the sound have changed significantly!
Everyone knows the phenomenon in HiFi that the sound changes due to a voltage change on the ground without a relevant signal change being recognized. An assumption that we have checked a thousand times over is that it is not a signal change, but rather nerve disorders Potential vortex is responsible for the sound degradation.
The theoretical foundations come from Dirty power Research by Prof. Dr. Magda Havaswho researched the nerve disorders associated with harmonics on the power grid.
Equipotential bonding the key to good sound
The connecting cables then emit the interference when we have standing waves on the cable, a voltage drops across the cable or the potential that carries the voltage is without a screen.
Standing waves
Standing waves occur when the wave resistance of the individual components is not adjusted. So if the socket does not fit the plug, the plug does not fit the cable, etc. Since an interference spectrum up to over 20MHz has to be measured on the ground, the characteristic impedance is very important. E-field measured on the cinch cable in Dirty power Range from 2.000 Hz.
We therefore use a third cable, which avoids reflections and standing waves via a special connector cable system with wave impedance-balanced connectors and cables. In this way, the disturbances on the masses can be balanced out without emitting disturbances.
Voltage drop across the cable
If, as seen above, interference is balanced out via the ground line of the connecting cable, no interference is emitted. But if the impedance of the cable is too high, a voltage drops across the cable and this creates a signal error.
This is why our cables have cross-sections of up to over 9mm² for the crowd. Silver-plated, coaxial conductors are also used to reduce the resistance in the HF range. We achieve a line that extends from the NF range to well into the MHz range using 2-way cable technology.
Mass interference without a screen, the sound killer
Today's cables are all shielded with a ground contact. In this way we enable the masses to radiate their disturbances as a field source. This is the biggest problem and corresponds exactly to the problems that lead to nerve disorders and sound deterioration. Therefore, our cables are necessarily all with ours Nano Shield screen provided which on Earth potential was laid. So we put a field sink directly around the mass as a field source and thus prevent the radiation of interference.
Vortex HiFi equipotential bonding is the technical and sonic revolution when it comes to connecting two devices.
