Mic Preamps
Tube MP
Project Series

The Tube MP Project Series is a professional quality audio interface that lets you connect microphone, instrument, and line level signals to a mixer or other audio input. This hybrid design is the latest in a long line of ART tube preamps. We took our legendary Tube MP series and updated every aspect of the design, inside and out, while still maintaining a compact, reliable, and cost effective product. From the new all-aluminum stackable chassis to the precision LED level metering circuitry, we have improved virtually every aspect of our already successful Tube MP series. With up to 70dB of clean musical gain and high output signal drive capability the cold digital world will melt with your mixes! Charge up your creativity with the Tube MP Project Series!

Optional ART SM1 stand mount securely attaches the Tube MP Project Series to any microphone stand for live stage or studio applications is available.
