ART Tube MP Tube Preamplifier

TubeMP.jpg (16637 bytes)   

I have two different types of ART preamp here: the original Tube MP and the newer Studio V3 version. The Tube MP is just a simple mic/line/instrument preamp which uses a 12AX7 vacuum tube operating in what's called a "starved plate" design.  The term starved plate simply refers to the tube operating voltage (typically less than 50 volts) which is lower than normally found in more expensive tube preamp designs. The lower operating voltage allows the tube to distort more easily resulting in a "warm" sound. The newer V3 version adds an output limiter and some additional voicing control for many common studio instruments and vocals.
