ART Pro VLA III Optical Compressor
The ART Pro VLA III is a two-channel optical compressor designed for studio applications requiring smooth, musical dynamic control. It supports dual mono or linked stereo operation and incorporates an authentic 12AT7 tube stage. Suitable for tracking, mixing, and mastering, it provides transparent control or warm coloration depending on voicing.
It features variable threshold, ratio, attack, and release controls, along with input, output, and gain-reduction metering. The unit includes switchable tube or solid-state voicings, extended ratio options, and selectable +4 dBu / -10 dBV operating levels. Rear-panel connections include balanced XLR and 1/4" inputs and outputs.
