The Solid State Logic THE BUS+ stereo processor is an analogue dynamics unit based on the original SSL Bus Compressor design and expanded with additional processing and routing capabilities for modern music production workflows. It features selectable operating modes including Classic Stereo, Dual Mono, Mid-Side, and Σ S/C Stereo, along with digitally controlled stepped settings for consistent parameter recall. The unit integrates a 2-band dynamic analogue equalizer with configurable signal-chain placement, expanded attack and release options, multiple compression ratios, and a MIX control for parallel compression. Additional functionality includes external sidechain input support, transient expansion capability, moving-coil gain reduction metering, and high-headroom analogue circuitry for integration into professional recording, mixing, and mastering environments.
