Extreme Flexibility

The MPDI-4 is as musical as it is powerful and flexible. It features 4 individual Mic Preamp/DI circuits housed in a single 1RU chassis.  With bypass-able transformers, switchable output headroom, and adjustable THD characteristics, the sound of the MPDI-4 can range from astonishingly pristine to warm, thick, and harmonically colorful. It may well be the only preamp that is truly perfect for every situation!
