This is the 500 Series version of the 73MP (a mic pre-amp version of the 1073 equaliser) having the same well-known characteristic Class A sound with its harmonically rich low end, slight resonant highs, and maintained focused mids.
Two selectable impedances makes the MPL works well with a variety of microphones.
As a coloured and versatile mic-pre, the MPL maintains its sonic signature across a wide bandwidth.
