how it works

Audio Systems and Magnetism

High Fidelity Cables uses magnetic conduction technology to preserve the quality of audio signals and repoduce music more accurately.

Most people think of an audio system as an electrical device. It would be more accurate to call it a magnetic device. Electricity powers the components, but it's magnetism that makes the music. It is a magnetic force that moves your speakers, causing them to vibrate and create sound.

This magnetism at the end of your signal path actually begins at your wall outlet, and is present throughout your entire system. The AC (alternating current) power drawn from your wall produces a magnetic field. This field is actually a series of waves whose frequencies vary with the electrical signal. Electricity induces magnetism, and vice versa: the two are inseparable.

The Lightbulb Experiment

We can perform a simple experiment to observe the magnetic component of AC power. If we plug in a lightbulb to a wall outlet, it draws power at 60 Hertz. When a magnet is placed near the bulb the filament begins to oscillate at a frequency of 60 cycles per second. This is evidence of the magnetism induced by AC.

Notice that when the magnet is placed by the bulb, the current-carrying filament appears to widen; this is actually the vibration of the filament. The alternating magnetic field of the AC signal is repeatedly being attracted and repelled by the permenant magnet. This is the same principle which makes your speaker cone vibrate.

From start to end, your audio system is dependent on magnetism to work. The AC power and magnetic waveform comes into your audio system, is modulated by your source, amplified through your amplifier, and sent to the voice coil on the speaker driver. Here it interacts with a permanent magnet and causes the speaker cone to vibrate and produce music.

Overcoming Problems in Audio Reproduction

Something most of us worry about when listening to music is distortion and signal loss degrading our beloved music. Since the audio signal is magnetic in nature, it can be controlled and preserved through the use of magnetic conduction.

Magnetic conduction is a new patented form of conduction, implementing specially arranged magnetic fields to concentrate the signal within the conductor. The electrons of the audio signal have a quantum spin which gives them their "magnetic moment" or charge. It's this charge which allows the electrons to react with magnetic fields. So if we use a magnetic conductor instead of a regular conductor, we can guide the electrons (the audio signal) through the conductor in a very precise way to reduce distortion and signal loss.

Preserving Signal Quality with Magnetism

This quick experiment demonstrates the effect a magnet has on the flow of electrons: Using a cathode ray tube to generate a stream of electrons in a vacuum, place a magnet near the tube and watch the electrons follow magnetic field lines. Before the magnetic field is applied, the electron stream is somewhat dispersed and hazy. When the magnetic field is applied in the proper orientation, the electron stream becomes more concentrated and the haze of stray electrons is collapsed into the center of the magnetic field.

Imagine this electron stream is an audio signal. In a regular conductor, the signal would be hazy and sparse, resulting in distortion and signal loss. In a magnetic conductor however, its magnetic fields attract the electrons into the center of the conductor, preventing escaping electrons and preserving signal integrity.
