ART Solo VLA Single-Channel Multi-Voice Compressor

Fast FET compression, or transparent opto compression with a tube gain stage? ART's Solo VLA lets you try both. Add in your dry signal with the Blend knob.

Whether it's to fatten up an instrument take, smooth out a vocal performance or prevent clipping while laying down tracks, the ART Solo VLA will elevate your projects to the next level.

The Solo VLA Multi-Voice Tube/Opto Compressor was designed to excel in applications where transparent, musical dynamic control is desired. The Blend control lets you combine the dry and processed signals for parallel compression, perfect for preserving your full dynamic range while adding fullness and sustain. Select between a pristine solid-state path or a class-A vacuum tube gain stage for warmer saturation.

ART's Solo Series of single-channel rackmount units have been developed for the recording enthusiast with a preference for simplicity.

Parallel Compression
The Blend control is used to dial in dry signal back into the output. This allows the mix in some of the original signal while using a heavy amount of compression to fatten up a track while retaining some of the dynamics.

Soft-Knee Leveling
The Solo VLA is a soft-knee leveling amplifier by design. Although read more capable of providing dramatic compression effects, the Solo VLA was designed to excel in applications where transparent, expressively musical dynamics control is desired.

Select between a pristine solid-state path or a class-A vacuum tube gain stage for warmer saturation.

Comprehensive Metering
A back-lit analog VU Meter can accurately display either the Output Level or Gain Reduction.
