Can Speakers be Used as Microphones?

A door once opened can be stepped through in either direction…

Okay, we promise that we’re serious people when we’re not making Doctor Who references (but we are never not making Doctor Who references so…paradox?). This video shows how a speaker, once removed from its enclosure, can be used as either a speaker or a microphone, thus exhibiting the beauty of transduction! Specifically, this is a good example of how electromagnetic transduction can work in both directions (electrical to acoustic transduction and acoustic to electrical).

Mixers Explained

Okay, we’ll admit it: the first time we saw a mixer were were a little freaked out by all the knobs. And then we kind of wanted to turn all of them all the time for no reason. Now using mixers are almost second nature. And while each company makes their mixers slightly differently, the basics are the same. This video explains one of the most important pieces of equipment in a recording studio or live sound reinforcement system.
