“A cable is a source of potential trouble connecting two other sources of potential trouble.”

The humor in this statement may be lost on those who regularly assemble sound systems.

But a reality of sound systems is that a signal accumulates noise as it flows through equipment and cables.

And once noise contaminates a signal, it’s essentially impossible to remove it without altering or degrading the original signal.

For this reason, no system can be quieter than its noisiest link. Noise and interference must be prevented along the entire signal path.

Delivering a signal from one box to another may seem trivial, but when it comes to noise, the signal interface is usually the danger zone, not the equipment’s internal signal processing.

Many - if not most - designers and installers of audio systems think of grounding and interfacing as a black art. How many times have you heard someone say that a cable is “picking up” noise - presumably from the air like a radio receiver?

Even most equipment manufacturers often don’t have a clue what’s really going on. The most basic rules of physics are routinely overlooked, ignored, or forgotten.

As a result, myth and misinformation have become epidemic!

It’s time to replace myth, misinformation, and mystery with knowledge and clear understanding.
