The handbook gives advice on choosing equipment (microphones, decks, cartridges, headphones, speakers), as well as setting it all up and getting the best sound out of it in whatever the venue a DJ might be playing. Charles Slaney gives some hands-on advice on transport, setting up a sound system at the gig, dealing with punters, looking after safety, and troubleshooting the equipment. On the business side of things there are some sample contracts that DJs can use for their own gigs.
The book also explores the way the way music works and explains how to mix musically and smoothly. The publishers tell us that it shows DJs how to build a mood and understand rhythm while it also explains how sound works, and the organic process involved in the mix.
