The Pro Channel from ART is the latest offering from the world’s most popular tube dynamics processing manufacturer. ART engineers have combined the world-renowned Pro MPA, Pro VLA, and Tube EQ into a single product – creating the world’s best-sounding and most affordable professional recording channel.

The Pro Channel features many new and exciting design enhancements to ART’s pro and home studio staples, including the addition of a Variable Mu circuit to the compressor module. The Pro Channel allows you to select between ART’s award winning optical/tube compressor or the coveted Variable Mu circuit (a design made popular by the sound of the old broadcast limiters – now costing thousands of dollars). The Variable Mu circuit is fast, fat and a bit aggressive, and is guaranteed to become a legend among compressors as has the Pro VLA. The four-band parametric equalizer has selectable Q for the two sweepable mid-bands. As with all design elements of the Pro Channel, these Q options were fine-tuned by some of the industry’s top studio and live-sound engineers. Likewise, all new additions were made without compromise to the sound of the original designs (Pro MPA, Pro VLA, Tube EQ), which have become standards in professional studios and FOH rigs around the globe.
