The Pro-VLA is a tube driven Vactrol-based Compressor / Leveling amplifier designed to excel in any professional audio application, including 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 the ideal dynamic control device for critical studio and live sound applications.
