The MP221 is a four input preamplifier, 2 XLR microphone inputs with phantom power and 1 line level input for balanced or unbalanced connection and a twin unbalanced phono input. The single electronically balanced output can be connected to balanced or unbalanced loads.

The inputs are fully protected. In the event of an overload condition of any amplifier section, the overload warning LED will illuminate.
