What is Phantom Power?

By

Definition: Phantom Power is a DC voltage sent through a microphone cable to power a microphone or associated device. It's standard feature in most audio equipment.

It is used most commonly with condenser microphones, but is sometimes used to power DI boxes and effects pedals, too. Phantom power is usually 48 volts (sometimes less; you'll see it as low as 12v), and sent to a microphone through the cable from your mixer or preamplifier. Sometimes, you'll find preamps that don't offer phantom, so you'll have to provide a phantom adapter.
