Plug-in power is a low-voltage power supply used by certain microphones, particularly compact electret condenser microphones. It provides the power required for the microphone's internal electronics and is commonly found on portable recorders, cameras and wireless transmitters.
Which Microphones Use Plug-in Power?
Plug-in power is primarily used by electret condenser microphones, including many:
- Lavalier (lapel) microphones.
- On-camera microphones.
- Compact headset microphones.
These microphones typically require only 3–5 V to operate, which is significantly less than traditional phantom power.
Plug-in Power vs Phantom Power
Although both supply power to microphones, plug-in power and phantom power are designed for different types of microphones.
- Plug-in Power (3–5 V) – Used by compact electret condenser microphones connected via 3.5 mm microphone inputs.
- Phantom Power (+48 V) – Used by professional XLR condenser microphones connected to mixers and audio interfaces.
Using Plug-in Powered Microphones with XLR Equipment
If you want to connect a plug-in powered microphone to equipment that only provides phantom power, you'll need an adapter that converts phantom power into plug-in power.
