The Basics of Phantom Power
Phantom power, also known as phantom feed or 48V phantom, is a type of electrical power supply used to energize condenser microphones, active ribbon microphones, and other devices that require an external power source. In essence, phantom power is a DC voltage (typically 48V) sent through the microphone cable to power the internal preamplifier or impedance converter of a condenser microphone.
Did you know? Phantom power gets its name from the fact that it is an invisible or “phantom” voltage that is present on the microphone cable, but not actually connected to the audio signal.
How Phantom Power Works
Phantom power operates on the principle of electrical isolation, which means that the power supply is separate from the audio signal. This isolation is crucial, as it prevents electrical noise and hum from being introduced into the audio signal, ensuring a clean and clear sound.
Here’s how it works:
- The phantom power supply is typically built into the mixing console, audio interface, or microphone preamplifier.
- The supply voltage (usually 48V) is sent through the microphone cable via the XLR connector.
- The microphone’s internal preamplifier or impedance converter uses this voltage to amplify the audio signal.
- The amplified signal is then sent back through the microphone cable to the mixing console or audio interface.

What is Phantom Power?
Phantom power refers to the power consumed by an electrical device when it is turned off but still plugged into a power outlet. This power is often referred to as “vampire power” or “standby power”. It’s the energy used to power features like remote controls, clock displays, and instant-on capabilities, even when the device is not in use.
Phantom power can be found in many devices, including TVs, computers, phone chargers, and kitchen appliances. It’s an often-overlooked aspect of energy consumption, but it can add up to a significant amount over time. According to the U.S. Department of Energy, phantom power can account for up to 10% of a household’s total energy consumption.
How Does Phantom Power Work?
Phantom power works by drawing a small amount of electricity from the power grid, even when a device is turned off. This occurs because many modern devices have features that require a constant flow of power, such as remote controls that need to be ready to respond to commands at any time. When a device is plugged into a power outlet, it can draw power from the grid, even if it’s not actively being used.
Some devices, like TVs and computers, have multiple modes of operation, such as standby or sleep mode. In these modes, the device is still consuming power, even though it appears to be off. This power is often used to maintain the device’s internal clock, power remote controls, and perform other functions that require a small amount of energy.
How Much Energy Does Phantom Power Consume?
