Two-channel opto-compressor with tube character and flexible voicing
The ART Pro Audio Pro VLA III is a 2-channel opto-compressor in rack format that combines classic analog dynamics processing with modern flexibility. As the direct successor to one of the best-known ART compressors, the third version remains true to the proven concept of optical compression, genuine 12AT7 tube and musical control behavior, but expands the range of functions specifically for current studio workflows. hether for smoothing individual tracks, compressing vocals, taming dynamic instruments or as a gentle bus compressor for more cohesion in

The Pro VLA III works with an optical compression circuit that is known for its rather soft, musical and organic control behavior. This is exactly what makes it interesting for sources where compression should help noticeably without killing the performance. Voices, basses, guitars, synth pads or even complete subgroups benefit particularly well from this type of dynamic processing.
Thanks to the dual-mono mode or the coupled stereo mode, the versatile compressor can be used for individual signals as well as on stereo sums or busses.

Extended ratio range for finer compression
Another new feature is the extended ratio range down to 1.25:1, which is particularly interesting for subtle interventions, for example on stereo sums or in the mastering area. This means that the Pro VLA III is not only able to make a significant impact, but can also work very finely and musically when just a hint of control or glue is required.
More headroom, less noise, better stereo symmetry
Compared to its predecessors, the new version offers more headroom, less background noise and improved channel symmetry in stereo link mode. This is particularly important for stereo busses and mix applications, as the left and right sides work together more cleanly and stably as a result.
Full control directly on the front
Each channel offers variable controls for threshold, ratio, attack,
This makes the Pro VLA III not only musical, but also pleasantly clear in everyday use.
The rear panel features balanced XLR and 6.3 mm jack inputs and outputs. It is also possible to switch between +4 dBu and -10 dBV, which facilitates integration into different studio or project studio setups. The universal internal power supply supports worldwide operation and saves on external power supply solutions.
The Pro VLA III is not an aggressive special effects compressor, but rather a musical all-rounder with an analog character. This is precisely why it is suitable for many typical studio tasks: Making vocals denser, controlling

The special appeal of an opto-compressor often lies less in its brutal control than in its ability to musically smooth and hold material together. This is precisely why devices like the Pro VLA III often work so well on vocals, basses or mix busses. They compress audibly without always sounding like a compressor. This often makes them more valuable in everyday studio work than particularly aggressive special solutions.
