ART Pro VLA II 2-Channel Compressor

Superior performance and an incredible tone makes the ProVLA II and indispensable tool for tracking, mixing, mastering, dynamic control of live sound sources or for use in broadcast audio.


Capable of delivering a far more musical natural sounding and sonically transparent compression than competitive units in its class, the ProVLA II uses an Opto-electronic circuit rather than the more typical design VCA driven level detection circuit. 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 audio applications.


Exceptional signal integrity with extremely low noise and low distortion is achieved in the ProVLA II by utilizing a transformerless design throughout.

    I use this on electric guitar guitar, bass, vocals, acoustic instruments and drums, and on the master mix, all great. Highly transparent but gives a nice tube warmth as well. Used in many pro studios and as good as compressors costing three times the price. A subtle compressor at a bargain price.
