The new ART ProMPA II is the next generation in affordable high-performance microphone preamp technology. Each microphone input circuit, with selectable 48v phantom power, features variable input impedance which can radically vary the overall performance of any high-quality dynamic or ribbon microphone. The ProMPA II can be configured for dual mono or stereo operation with selectable mid/side mic support, summing the adjacent channel, to decode left/right signals.

The ProMPA II can operate at either a low or high plate voltage on the two integrated hand-selected 12AX7 tubes for wider variation of preamp tone and performance. Large back-lit analog VU output meters display input or output levels while multi-colored LED arrays, with average or peak hold, show tube gain.

Housed in a standard 2u space rack-mountable steel chassis, the ProMPA II is designed to deliver years of reliable operation in the studio, production facility, or on the road for live sound reinforcement.
