ART PRO VLA II
ProVLA II is a tube-driven compressor/leveling amplifier utilizing Vactrol® technology, designed to excel in any professional audio environment. Superior performance and incredible sound make the ProVLA II an indispensable tool for tracking, mixing, mastering, dynamic control of live sound sources, and for broadcast audio applications.
The ProVLA II can deliver a far more musical, natural-sounding, and sonically transparent compression than competitive units in its class because it uses an opto-electronic circuit instead of a VCA-driven level detection circuit. This VCA-less design, coupled with a 12AT7 vacuum tube in the gain stage, makes the ProVLA 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.
VACTROL® TECHNOLOGY - Unlike typical compression units that use Voltage Controlled Amplifiers (VCA) to handle level detection, the ProVLA II’s opto-electronic design allows for far more transparent and musical sounding compression without sounding aggressive or unnatural. This Vactrol® based optical electronic circuitry is the basic component of the classic highly sought after compressors of the past. The Vactrol® design allows the ProVLA II to react to audio signals in much the same way the eye naturally adjusts to fluctuations in light levels – smoothly, quietly, and almost imperceptibly.
SOFT KNEE LEVELING - The ProVLA II is designed as a soft knee leveling amplifier. Although capable of providing dramatic compression effects, the ProVLA II was created to excel in any application where transparent, expressively musical dynamics control is desired.
COMPREHENSIVE METERING - Large, highly visible backlit analog VU meters accurately display input and output levels while extremely fast 10-segment LEDs display gain reduction. For added functionality, the LEDs display both average level for mastering & mixing applications or peak hold for monitoring individual sources when tracking audio.
VERSATILE I/O - XLR and 1/4-inch TRS balanced inputs and outputs are provided to ensure the ProVLA II can connect with any audio source or hardware. A +4dBu/-10dBu mode switch optimizes ProVLA II I/O for either consumer or professional equipment.
