Tube-driven and Vactrol-based, the ART Pro-VLA II is a two-channel; compression and leveling amplifier that is suited to nearly any situation a musician may find themselves in: mixing, mastering, live sound, tracking, and even braodcasting. Thanks to its VCA-free design, you're able to add more compression without detracting any of the organic musicality from your output. Variable output, ratio, and threshold controls allow you to manage your dynamic output and active balanced XLR and 1/4" inputs and outputs make the Pro-VLA II compatible with a variety of potential rig components.
