Can USB provide 48V phantom power?

Phantom power has very little current requirements, so a step-up voltage converter can easily provide +48V from USB power.

Is phantom power the same as 48V?

Phantom power, commonly designated as +48V or P48, was designed to power microphones without using bulky external power supplies such as the ones required for tube microphones. It’s a way of sending the DC electrical current required through a balanced XLR cable.

Where does 48V phantom power come from?

Phantom power is a DC voltage (typically +48 V) that provides power to the active components within certain active microphones. This electric power is transmitted through the same balanced audio cables that carry the audio signal. The term “phantom” comes from the fact that there is no obvious power cable.

Does phantom power only work with XLR?

* Phantom power is typically supplied only by a mixer with an XLR input. If the mic requires phantom to operate and not phantom is present at the mixer input, the microphone will not produce a signal. The mic connects to this device. The output of the phantom supply connects to your mixer.

Can you get phantom power from USB?

Yes. Phantom power requirements from current are small per channel. There are many two channel interfaces that can provide phantom power and run off of USB bus power.

How do I supply my phantom power?

Phantom power sends the correct power (+48V) to a condenser microphone via an XLR socket and cable. Plug in your condenser microphone, and switch on phantom power on the correct channel, and bingo- your microphone will spring to life.

How do I get phantom power?

You can usually plug either type of mic into a mixer that provides phantom power, and the condenser mic will detect and use the power, while most dynamic mic will ignore it. This trick is why the scheme is referred to as phantom—it’s there for mics that need it, but generally invisible to others!

How do I turn on phantom power?

On the right side of the mixer, you’ve got a +48V PHANTOM button to engage phantom power. This will also activate a light confirming that phantom power is active. If you find this button aside from the inputs on a mixer, it will typically engage phantom power for all of the XLR channels at once.

What voltage is phantom power?

12 to 48 volts
Phantom is usually a DC voltage ranging from 12 to 48 volts. Microphones draw current from this voltage based on their needs. Balanced microphone interconnections have two signal conductors relative to a ground conductor….Microphone Current Draw.

Microphone	Voltage Specified (volts)	Current Draw (mA)
Schoeps – most	48	4

Do you need an audio interface if you have phantom power?

Phantom power makes the condenser microphone work, but the audio interface is a device required for the audio to get into and out of the computer. So, unless you have a way to connect the microphone to the computer, you will need an audio interface.

Can I use a condenser mic without phantom power?

Although you may still get a signal from some condenser mics without phantom power, it will be so weak that it will be barely audible. In most cases, you won’t get a signal at all. Condenser mics need power to operate correctly whether that be battery or phantom power.
