Church Audio & Acoustics Glossary

This glossary is being put online to help with unfamiliar words when visiting this site. Since this is a web site devoted to church audio and acoustics, the glossary will cover common words used when talking about church audio and acoustics. This is only one step beyond typical glossary listings, since it's specific to churches. New words will be added as they come up; if you have any suggestions, please let us know!

There are a number of words that relate to churches in general, as well as video and lighting terms. You usually need to know a little of everything...

Many words don't have definitions yet, we're working on it. This is a project in motion; it will be updated as time permits. If you would like to contribute a definition for any words listed here, just let us know, thanks!

X

X-Y micing

    Proceedure of positioning two microphones such that their elements are in cloe proximity to each other, but aimed at different vectors. Variations include the elements directly above each other, or simply with the grilles touching. Typically used in stereo micing practices, but is mono compatible. Useful in creating altered polar patters from what each microphone offers independantly while minimizing comb filtering.


XLR

    Type of connector developed by Cannon company. It's the standard connector used for all professional microphone wiring and some line level wiring. Typically indicates balanced wiring. Standard microphone wiring is for pin 1 to be the shield, pin 2 is the + (positive/hot), and pin 3 is - (negative). Typically three pin connectors, but may be more (i.e., 4, 5, 6, etc.).

No, we didn't write all of these definitions ourselves. What we did was take a word, read several definitions from books and listings on the internet, then write our own version. In some cases we used phrases word-for-word, but usually we reworded the definition to be more clear and applicable to church audio and acoustics.

EXTREME thanks to Stephen Lund of LaRue Electrical Specialties, who began writing a glossary of terms, never fully completed it, but has passed his words and definitions on to us for use in this glossary. There are many definitions he had written that were so simple to understand, we took them as-is without any editing. We finally finished it! (...almost) Thanks a million, Stephen!
