Condenser mics require phantom power — DC voltage transmitted over an audio cable. If you ever wondered why it’s called phantom power, it's because power is sent using the exact same cable that's carrying the audio signal. Hence, it offers simultaneous transmission of both the power and the audio signal to the mic or audio tool over one single cable. You can think of a phantom power supply as an amazing way to have the right amount of power exactly where you need it.
How do you know which voltage range to choose? The answer is simple: just check your microphone's product specifications and look for their optimal voltage range. Then you look for a phantom power supply that is compatible with your mic's voltage. The most common phantom power units will usually supply voltage within the range of 12 to 48 volts. XLR female inputs and XLR male outputs provide connectivity to your signal chain.
A reliable phantom power supply will also be compact and portable, so that you can easily carry it wherever your music takes you or move it around the studio. Some models can even be powered by internal batteries for total on-the-go-convenience, as well as with external AC power supplies for longer sessions. Highly-regulated phantom power supplies will offer you a continuous voltage source, even with a heavily-loaded input.
