Will phantom power damage a keyboard?
If a single-ended (unbalanced) output device such as a keyboard, consumer tape deck, sound card, or receiver is connected to any balanced preamp, make certain phantom power is turned off on that input. Depending on the design of the device, its output can be permanently damaged if phantom is applied.
What does 48v phantom power mean?
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.
Is phantom power always 48v?
The worldwide standard for phantom power is 11 to 52 volts of DC (typical studio mics run on 48v). Your preamp will typically have a button labelled 48v, which allows you to turn this on/off.
Is it bad to leave phantom power on overnight?

How does Phantom Power work on a condenser microphone?
Condenser (or Capacitor) microphones however need an electrical current to move the diaphragm, which is what captures the sound. This is where the Phantom Power comes in, Phantom Power (the 48v button) sends 48 volts of electricity via the XLR cable which activates the capacitor and essentially ‘turns on’ the microphone.
