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.\u003c\/p\u003e \u003cp\u003eCapable 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.\u003c\/p\u003e \u003cp\u003eExceptional  signal integrity with extremely low noise and low distortion is achieved in the  ProVLA II by utilizing a transformerless design throughout.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eVactrol Technology\u003c\/strong\u003e\u003cbr\u003e   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.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eSoft Knee Leveling\u003c\/strong\u003e\u003cbr\u003e   The ProVLA  II is a soft knee leveling amplifier by design.
