If you're talking about the top one, it's called a PC terminal. Hooks up to a lot of flashes & it's more common on professional level equipment like yours. The outlet has been around for a long time. You can hook radio slaves to it, or use a cord to trigger monolights & units with powerpacks like this one: http://www.bhphotovideo.com/c/buy/Lighting-Kits/ci/11255/N/4232862224 ...We're talking gobs of power here and something you don't learn to use in a day.
