XLR Inputs with Phantom Power

These inputs are designed for low-impedance microphones or equipment that has a mic-level, balanced output (often called a direct out)

Also these XLR inputs are phantom powered.  Phantom power is a small amout of power that is necessary when using most condenser mics.  Condenser mics allow you to capture frequencies that are unachievable by most dynamic mics.  Most condenser mic require either an internal battery or an expensive adapter.  The Profile System One mixer provides 15-volts of power the the XLR jacks which will not cause damage to any dynamic or non-condenser microphone.
