Bill Whitlock 04/16/13 06:01 PM,“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.… View this story

This is an interesting topic because sound is both electrical and physical. Sound systems turn physical movement of air into electrical signals, then process and amplify those signals (sometimes changing them into streams of 1s and 0s and back), and finally turn those amplified signals back into physical air movement. It’s… View this story

Although the first instinct might be to take a “shotgun” approach and start checking plugs, connections, cables, etc. in a random fashion (i.e., “panic”), a tried-and-true troubleshooting method… View this story
