Tube MP Studio


The original ART Tube MP put professional-caliber tube preamplification into the hands of thousands of musicians and recordists who wanted great tube tone in a compact and flexible package.

The Tube MP Studio extends the range of applications by adding an output protection limiter (OPL) to precisely control output peaks, and analog VU metering to aid in setting and maintaining proper signal levels.

The Tube MP Studio can be used in a wide variety of applications including recording, project and home studios, where its metering functionality and OPL circuitry really shines. It also functions as a direct box, with impedance matching and preamplification for instrument or line-level sources.
