What power source is typically required for a condenser microphone?

A condenser microphone typically requires phantom power to operate. Phantom power is a method of providing power to the microphone through the same cable that carries the audio signal, usually via XLR connections. This power is essential because condenser microphones rely on a capacitor to convert sound waves into electrical signals, and this capacitor requires a voltage supply to function properly.

Phantom power typically delivers a voltage of 48 volts, but can vary depending on the microphone and equipment used. It is favored in professional audio environments because it allows for clear audio transmission without the need for battery replacements or additional power sources.

While some condenser microphones can operate on batteries, and USB microphones draw power from a computer's USB port, phantom power is more commonly used in studio settings and live sound applications where high-quality audio capture is paramount. Options like solar power are not standard for microphones, making phantom power the most relevant source for professional condenser microphones.
