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 in the hi-fi world is familiar with the phenomenon that a change in voltage on the ground plane can alter the sound, even without any discernible change in the signal itself. One hypothesis we've tested thousands of times is that it's not a signal change, but rather interference from potential vortices that is responsible for this deterioration in sound quality.
The theoretical basis comes from the Dirty Power research of Prof. Dr. Magda Havas , who investigated nerve disturbances caused by 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.
Therefore, our cables have cross-sections of up to 9 mm² for the ground connection. Furthermore, silver-plated coaxial conductors are used to reduce resistance in the RF range. We achieve a transmission range extending from the AF range well into the MHz range through a two-way cable technology.
Mass interference without a screen, the sound killer
Today's cables are all shielded with a ground connection. This allows the ground to radiate its interference as a field source. This is the biggest problem and corresponds exactly to the issues that lead to nerve interference and sound degradation. Therefore, all our cables are equipped with our Nano Shield shield , which is connected to ground potential . This creates a field sink directly around the ground as the field source, thus preventing the radiation of interference.
Vortex HiFi equipotential bonding is the technical and sonic revolution when it comes to connecting two devices.
