Pro VLA II Studio Vactrol Tube Compressor

Product Information

The ProVLA II is a tube driven Vactrol-based Compressor / Leveling amplifier designed to excel in any professional audio environment. 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.

Unlike typical compression units that use Voltage Controlled Amplifiers (VCA's) to handle level detection, the Pro VLA II's Opto-electronic design allows a far more transparent and musical sounding compression without sounding aggressive or un-natural. This Vactrol based optical electronic circuitry is the basic component of the classic highly sought after compressors of past. Vactrol design allows the ProVLA II to react to audio signal in much the same way the eye naturally adjusts to fluctuations in light levels - smoothly, quietly and almost imperceptibly.

The ProVLA II is a soft knee leveling amplifier by design. Although capable of providing dramatic compression effects, the ProVLA II was designed to excel in any application where transparent, expressively musical dynamics control is desired.
