ART MPA Gold Microphone Preamplifier

Like the Digital MPA, the MPA Gold features Variable Input Impedance.

Variable Input Impedance is intended to optimize the MPA Gold for the widest range of microphones.

Variation of the input impedance of a microphone preamplifier changes the load against which the microphone has to push.

This variation dramatically alters the performance of a microphone, and creates numerous sonic possibilities for microphone performance.

The variable impedance control of the MPA Gold is infinitely variable, as opposed to steps.

This allows users much finer control over the tuning of the impedance.
