A soundboard, or mixing console, is an electronic device used to mix audio signals, and is used in sound recording, sound reproduction and sound reinforcement systems. The console includes microphones, signals from electric or electronic instruments, and other devices. The soundboard may record either from analog or digital. The purpose of the mixing console is to process input signals with amplification and EQ, and to combine those signals in many different ways.

I can’t think of anyone that hasn’t used the soundboard in any other way than it was built to be used. I’ve never used this technology, for multiple reasons. Soundboards have been used in music recording since 1958 when EMI records installed one as Abbey Road Studios. One example I can give you for this is Queen’s Seven Seas Of Rhye, which uses many of the soundboard’s techniques.
