Solid State Logic Bus Comp Classic Stereo Bus Compressor

Put the sound of one of recording's most recognizable mix-bus compressors back at the center of the rack. The Solid State Logic Bus Comp Classic brings the punch, glue and authority of the classic SSL Bus Compressor into a modern 1U format, built by the original designers around the original circuit. High-performance THAT 2181 VCAs provide the foundation for its stereo compression, while precision-stepped Attack, Ratio, Release and side-chain high-pass filter controls retain the familiar hands-on workflow that has made SSL bus compression a studio standard for shaping mixes, stems and other stereo sources.

Variable VCA Drive Moves From Clean to Gritty SSL Character

The Variable VCA Drive control provides a continuous way to shape the character of the compressor itself. At one end, the VCAs operate balanced for the clean, low-distortion SuperAnalogue character associated with SSL's 9000 K console; push the control further and the circuit moves toward the unbalanced VCA behavior and increasing distortion associated with the original FX384 Bus Compressor and 4000-series sound. This gives engineers control over more than compression dynamics, allowing the Bus Comp Classic to move from clean mix-bus compression to a more aggressive, characterful response.

Stereo Side-Chain Control Expands Mixing and Stem Workflows

A genuine stereo external side-chain input opens the compressor to creative keying techniques while also supporting more consistent stem creation. Engineers can feed the complete mix into the external side chain while bouncing individual stems, allowing each stem to react to the same compression-driving signal used by the full mix. Six-position stepped controls for Attack, Ratio, Release and side-chain high-pass filtering provide repeatable settings for different mixing applications.

Classic SSL Bus Compression in a Compact 1U Format

The compact 1U rackmount design brings the original SSL Bus Compressor circuit into a space-efficient format, complete with an integrated switched-mode power supply. From clean, controlled dynamics to more aggressive VCA coloration, the combination of stepped compression controls, variable drive and stereo side-chain functionality gives engineers flexibility across mixing and stem-production workflows. For studios seeking the familiar SSL compression character with expanded tonal control, the Solid State Logic Bus Comp Classic stereo bus compressor combines classic circuitry with practical modern features.
