Technical Insights of Audio Sound & Reinforcement

I’m supposed to be giving a speech in about a week to a group of DJs regarding “Technical Insights of Audio Sound & Reinforcement.”

This is supposed to be 30-45 minutes in length.

I’ve come up with the following possibilities:

  • Power matching speakers to amps/benefits of powered speakers
  • new tech in DJ – conectiv/serato
  • Why there are so many microphones and what they are all for

Anyone have any other thoughts or suggestions? Specifically something that would be of use to DJs.
