PRO MPA II Reference Series

The ART PRO MPA II Reference Series delivers unmatched warmth, presence, and clarity, making it the ideal input solution for any critical live sound or recording application. Its Class-A tube design with variable input impedance and selectable tube plate voltage makes the PRO MPA II Reference Series one of the most versatile high performance two-channel microphone preamplifiers in its class.

Everyone that is into tubes eventually has the itch to swap them out and try something different. In this limited edition ART has done it for you. They used the lower noise version of a 12AX7 which is the 7025. This tube, besides having lower noise than a conventional 12AX7 due to its design, is also more roadworthy. Not only that but ART custom-matched the pair. They also updated all connections throughout with gold plated jacks allowing for lower noise. Custom metering and knobs further set this upgrade apart from their award-winning ProMPAII model.
