Conclusion
We’ve covered a lot of ground in a short time. Some of the concepts presented may not be crystal
clear the first time through. Take the time to read them through and attempt to understand them.
Don’t let the numbers scare you; you can skip them until you get deeper into the subject.
The subject of noise is not a simple one. There are many different noise sources, and perhaps twice
as many cures. You can take a shotgun approach to the problem and perhaps be successful 50% of
the time. The rest will require careful attention to detail as well as careful analysis of the problem.
In your customer’s ears, anything that isn’t music is probably noise. You, as the installer must be
able to separate out the various noise sources and deal with each of them individually. Most wiring
shortcuts end up costing you more in troubleshooting time than they’re worth. Learning how to
troubleshoot a noise problem is one of the more subtle things that a successful autosound installer
needs to understand, Understand it, and in the end, you’ll find that more of your systems work
properly when they’re first turned on. Isn’t that what it’s all about?
Remember:
• Ground isn’t ground.
• Check for ground loops.
• Match signal levels between components.
• Observe good wiring practices.
• Know your noise sources.
