For our purposes, a transducer is an electronic component that transforms one type of energy into another. Some examples: A microphone converts sound into electric current. Likewise, a speaker converts electric current into sound. Other common transducers include magnetic guitar pickups, piezo pickups, phonograph cartridges (remember those?) and tape heads. One of the main challenges we all face (whether we know it or not) is overcoming the physical limitations transducers put on our ability to reproduce the extremely wide dynamic range of acoustic sounds… deadly enemies of your gear!
