DIGITAL MPA II OVERVIEW – FEATURES AND
GENERAL INFORMATION
:
The ART DIGITAL MPA II microphone preamplifier features a new low noise, high performance
preamplification circuitry, designed for superior audio fidelity. Building upon the quality and success of
great sounding products like the Pro MPA and MPA GOLD, ART engineers set out to develop the
next generation of professional microphone preamplifier. The DIGITAL MPA II is the culmination of
years of research and development, and sets a new standard for quality and value. Professional
