ART Pro MPA II Microphone Preamp - Secondhand

Full Description

The 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.
