ART Pro VLA II Two Channel Vactrol-based Compressor

The ART Pro VLA II is a dual-channel tube vactrol-based studio compressor and leveling amplifier. The Pro VLA II uses an Opto circuit, with a 12AT7 vacuum tube in the signal path. The transformerless design makes the Pro VLA II ideal for sculpting transients and dynamic range. With its soft-knee design, the Pro VLA II will give you smooth musical results in the studio. VU metering and XLR / TRS connectors make for a very professional, intuitive, and cost-effective dynamics processing unit.

    ART Pro VLA II Features:

    • VCA-Less Vactrol Opto-Compression Design

    • 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/-10dBu Mode Switch Optimizes Pro-VLA II For Interface with Professional OR Consumer Grade Components

    • Active Balanced XLR And ¼-Inch Inputs & Outputs

    • Toroidal Transformer Reduces Mechanical & Electrical Hum
