THE GLOSSARY: A HAVEN OF NON- TECHINESS FOR THE NEOPHYTE

Just in case you’re new to the audio world, we’ve included a fairly comprehensive dictio- nary of pro audio terms. If terms like “clipping,” “noise floor,” or “unbalanced” leave you blank, flip to the glossary at the back of this manual for a quick explanation.

A PLUG FOR THE CONNECTORS SECTION

Also at the back of this manual is a section on connectors: XLR, TRS, Binding Post and Speakon connectors, balanced connectors, unbalanced connectors, and special hybrid connectors. If you plan on wiring your own cables, please visit this section before you start.

ARCANE MYSTERIES ILLUMINATED

Almost last but not least, we’ve included an appendix entitled Arcane Mysteries Illumi- nated. This section discusses some of the down ’n’ dirty practical realities of signal transmission, balancing a sound system, grounding, and bal- anced versus unbalanced lines. It’s a gold mine for the neophyte and even the seasoned pro might learn a thing or two.
