Phantom Powered Microphones. If you've ever done anything on the professional side of audio, you've probably run into a condenser microphone. These require power to work. Sometimes, that's a battery you put into the mic. Sometimes it's a separate dedicated power supply with a special multi-pin cable. But most often these microphones use phantom power. This is power delivered by a mixer or console, which uses the same cable that the audio comes back on.

Case study: Provocation. Provocation is a partial defence to an act of criminal violence, such as murder or attempted murder. The provocation defence dates back to the late Middle Ages, when courts and judges accepted that a man might respond violently if his honour, dignity or courage was insulted. Later, provocation became a legitimate partial defence for acts of violence.
