The ART Pro VLA III Tube Leveling Amplifier delivers smooth, musical dynamic control with the warmth and character that only a tube-based optical compressor can provide.

Designed for tracking, mixing, and mastering applications, the Pro VLA III offers a natural, transparent compression style that enhances performances without sounding overly processed—making it an excellent choice for vocals, bass, acoustic instruments, and full mixes alike. At the heart of the Pro VLA III is its opto-electronic gain reduction circuit, which reacts in a program-dependent manner for ultra-smooth compression that avoids harsh artifacts. Combined with a high-voltage tube stage, this design adds subtle harmonic richness and depth while maintaining clarity and headroom. Whether you're gently leveling a vocal or applying more assertive compression to a drum bus, the Pro VLA III retains musicality and detail.

Each channel features fully variable threshold, ratio, attack, and release controls, along with a switchable soft knee for transparent leveling or a harder knee for more noticeable compression. The onboard VU meters provide clear visual feedback for gain reduction and output levels, while stereo link capability allows for cohesive processing of stereo sources. With balanced XLR and 1/4-inch inputs and outputs, selectable +4 dBu or -10 dBV operation, and a robust rackmount design, the ART Pro VLA III integrates easily into any studio setup - from home studios to professional environments. Its combination of classic optical compression and tube warmth makes it a versatile and musical tool for shaping dynamics across a wide range of sources.
