Tube MP Project Series

The ART Tube MP Project Series is a professional quality audio interface designed to connect microphone, instrument, and line level signals to a mixer or other audio input. It features an extremely low noise discrete front end, providing up to 70dB of clean, "musical" gain and high output signal drive capability. The unit also includes a fast FET limiter to prevent overload, switch selectable input impedance, precision LED metering, and a built-in low noise phantom power supply.
