ART Pro MPA II Microphone Preamp Overview
The ART ProMPA II is a high performance, microphone preamp that can be configured for dual mono or stereo operation with selectable mid/side mic support, summing the adjacent channel, to decode left/right signals. Each mic input circuit, with selectable 48v phantom power, features variable input impedance which can drastically alter the performance of any quality dynamic or ribbon microphone.

Full Description
View Full DescriptionThe ProMPA II operates at either low or high plate voltage on the two integrated hand selected 12AX7 tubes for more variation of preamp tone and performance. The large, lit VU output meters display output levels while multi coloured LEDs show tube gain.
The ProMPA is designed to deliver years of reliable performance in your studio, production space or on the road for live sound reinforcement. The unit is housed in a standard 2u space rack-mountable steel chassis with CNC routed black anodizes aluminium face panel.
