The Xvive P1 Portable Phantom Power Supply is a low-noise, 12V / 48V power supply. It runs on an internal rechargeable battery and has enough power to run high-current microphones. The P1 allows you to use microphones and devices that require external power in any setup. The small size, light weight, rugged construction, and exceptionally low noise of the P1 makes it perfect for powering microphones to send a signal to mixing consoles, or any type of processor or recording unit, that does not supply phantom power. Long battery life and a bright LED battery indicator ensure that the microphone is properly powered throughout your recording session.
