Keys To A Proper Sound System

This could be a book in itself, so briefly :

- Good electrical supply. A separate circuit(s) is recommended. A sub-panel with an isolated ground is even better. You want to deliver clean and stable voltage to the equipment. Be careful about sharing neutrals with the rest of the building. Use a licensed electrician. Arthur Klem has an excellent website.

- Fat Loudspeaker Wire. We started with 12 gauge wire, when 10 gauge became available about 15 years ago, we switched to only using that for all loudspeakers. Hook up a stereo playback system with one channel 14 gauge and one channel 10 gauge and you'll hear quite a difference. The 10 gauge we use has over one hundred strands per conducter. Do not use solid core.

-Amplifiers. Use amps that have a 2 ohm rating and double or triple the power rating of the loudspeaker. Use one amp channel per loudspeaker. We want the sound system to just be "coasting" along and never stressed.

- Use a equipment rack. Even if it's just a small system, put a rack in, don't stack the pieces on a shelf.

- XLR's. Use balanced, low impedence XLR connections wherever possible. Use a converter like this if you need to have RCA jacks.

- Wireless microphones & Cellphones. They don't mix. Do not keep your cell phone in your pocket while you have a wireless mic. The radio frequency spectrum is very crowded and it's going to get worse.
