Audio physics and physiology: Sound physics and some human psychoacoustics · Descriptions used for sound and music

Noise stuff: Stray signals and noise · sound-related noise names · electronic non-coupled noise names · electronic coupled noise · ground loop · strategies to avoid coupled noise · Sampling, reproduction, and transmission distortions · (tape) noise reduction


Digital sound and processing: capture, storage, reproduction · on APIs (and latency) · programming and codecs · some glossary · Audio and signal processing - unsorted stuff

Music electronics: device voltage and impedance, audio and otherwise · amps and speakers · basic audio hacks · Simple ADCs and DACs · digital audio · multichannel and surround
On the stage side: microphones · studio and stage notes · Effects · sync

Requirements

Bipolar power
Enough power / planning

Clean power - The big discussion

Helpful components
Conditioning what you have
"Are linear power supplies better?"

Simple-ish practical supply

The quick and dirty starter

Probably the simplest decent option

On rectifier boards

Other design notes

On ground
On clean distribution
What's that about multiple cases and ground?

Other questions / Choices

Can I use batteries?
Aren't there readymade supplies?
Can I double up supplies?

From AC

Why 15V AC? Why not 12V AC?
Can I just use a single transformer?
Do I need a center-tapped transformer?
Could I use two 12V AC transformers?
Can I just use two 12V AC transformers?
Are there readymade bipolar AC supplies?
Can I just use a 24V AC transformer?

From DC

Can I make bipolar from two distinct 12V DC outputs?
Can I make two 12VDC from a single 24VDC supply?
Can I use switch-mode supplies?
Can't I just add linear regulators to switch-mode?
Can I use a computer supply?
Can I add more supplies to get more current?
Earthed or floating?
