ART Pro-VLA II 2-channel Leveling Amplifier/Compressor

The ART Pro-VLA II is a tube driven Vactrol-based compressor/leveling amplifier designed for tracking, mixing, mastering, live sound, or broadcast situations. By using an opto-electronic design, (as opposed to a more typical VCA driven level detection circuit) the Pro-VLA II allows more compression to be added to an audio source with a more natural, musical sounding output and virtually transparent dynamic leveling. This VCA-less design coupled with a 12AT7 vacuum tube in the gain stage makes the Pro-VLA II an ideal dynamic control device!
