Re: %26quot%3BThe Electronics of Audio%26quot%3B
Some more tidbits of
feedback --
* Chapter 1: audio isn't just a "type" of electrical signal, it's specifically a signal that can produce sound.
* mention the differences between digital and analog electronic sound signals. You don't have to elaborate too much on digital sound at all except to mention that it's there and is used (digital
coax), and that the electrical
pattern is very different from analog.
* so the focus of this document is then on analog, right?
* Suggest adding subchapter/section headings. Chapter 1 moves around between a lot of topics. It would be easier to navigate the chapter and use this as a reference guide if there were subchapter/section headings.
* Audience, I agree with others who say this would be a good primer/reference for technically savvy people and/or engineers who know electronics basics and want to understand pro audio equipment, how it works, and how to troubleshoot and resolve problems quickly. So in
line with some of the above topic suggestions, add topics that will help you understand how to get better, cleaner sound out of your PA equipment:
-
ground loop hum, how to detect and deal with
- dirty
neutral, how to detect and deal with
- summing amps (in the boards), and in general the difference in signal quality between high quality and low quality boards.
- noise floor, and how it propogates through the
system
-
gain structures, how there are many stages of
gain in a
system, and how not setting them all reasonably well can produce
clipping and/or high noise floors
- compressors, what's really happening inside
- wireless RF, the different types of noise and how to deal with
I know I personally would love to have a primer like the above. I own the
Yamaha handbook, have read through the first few chapters, but it's a pretty big document and not sure it covers all of the issues above. A targetted doc specifically to help sound engineers would be great.
Thanks. John
