The Tube MP Studio extends its 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. It can be used in various applications including recording, project and home studios, and as a direct box with impedance matching and preamplification for instrument or line-level sources.
