ART VLA-500 Series Form Factor Vactrol Compressor Module
The ART VLA-500 compressor module integrates the legendary VCA-less Vactrol-based compression technology from ART’s acclaimed Pro-VLA into a sleek 500 Series format. This unit delivers incredibly smooth compression and precise dynamic control tailored for professional audio environments.
Why Choose the VLA-500?
The real standout feature is its versatility. In addition to its pure opto-compressor core, the VLA-500 offers two unique, user-selectable tone shaping circuits. The ‘Punch’ circuit utilizes a J-FET Harmonic Enhancer to add even-order harmonics. Therefore, enriching the sound with a fuller tone and taming peaks. Meanwhile, the ‘Grit’ circuit applies frequency-dependent distortion to bring creative character to drums, percussion, brass, woodwinds, and vocals.
Precision Controls and Flexibility
With variable threshold, ratio, and output controls, the VLA-500 gives you detailed command over your compression settings. Its stereo and multi-channel linking capabilities support complex signal routing, while LED metering provides clear visual feedback for optimal adjustment.
Compact, Efficient, and Ready for Professional Use
The compact 500 Series form factor maximizes space in your rack while maintaining high performance. Its low harmonic distortion and broad frequency response ensure clean, transparent sound without unwanted coloration.
