ART Pro-VLA II 2-channel Leveling Amplifier/Compressor with Optical Compression (ProVLA / Pro VLA)

The ART Pro-VLA II is a tube driven Vactrol-based compressor/leveling amplifier designed for tracking, mixing, mastering, live sound, or broadcast situations. By using an opto-electronic design, (as opposed to a more typical VCA driven level detection circuit) the Pro-VLA II allows more compression to be added to an audio source with a more natural, musical sounding output and virtually transparent dynamic leveling. This VCA-less design coupled with a 12AT7 vacuum tube in the gain stage makes the Pro-VLA II an ideal dynamic control device!

FEATURES

• Vactrol Opto-Compression Design (no VCA)
• Mastering-Quality Audio Signal Path with Tube Gain Stage
• Enhanced Link Mode - While in stereo link mode, channel 1 level control acts as a master output level and channel 2 becomes a balance control between them, - optimizing the Pro-VLA II for use as a mastering tool
• Variable Threshold, Ratio & Output Controls
• LED Backlit VU Input/Output Level Metering
• LED Metering Indicates Both Average Level And Peak Hold
• Accurate Ten Segment LED Gain Reduction Metering
• +4dBu/-10dBV Mode Switch Optimizes Pro-VLA II For Interface With Professional OR Consumer Grade Components
• Active Balanced XLR And 1/4-inch Inputs and Outputs
• Toroidal Transformer Reduces Mechanical and Electrical Hum
