The Tube MP Project Series is a professional quality audio interface that lets you connect microphone, instrument, and line level signals to audio inputs to digital audio workstations as well as standard analog devices. ART took their legendary Tube MP series and updated every aspect of the design, inside and out, while still maintaining a compact, reliable, cost effective product, and added a USB output. From the new all-aluminum stackable chassis to the precision LED level metering circuitry, ART has improved virtually every aspect of their already successful Tube MP series and added USB connectivity.
