The Only End-to-End SSL Bus Compressor Emulation

Embarking on a ground-up re-design of the original SSL G Bus Compressor plug-in, UA’s team of engineers meticulously remodeled every nuance of the in-console and FX G384 rackmount specimens, including their unique CV (control voltage) summing. By capturing all of its circuit behaviors, the new SSL G Bus Compressor plug-in gives you all of the famed SSL hallmarks — punchy, transparent glue, and an ultra-accurate stereo image.

Original Recipe

From subtle and transparent dynamic control to more aggressive textures with peak limiting, the SSL G Bus Compressor plug-in’s simple, intuitive control set lets you quickly dial in what you need. The fixed Attack and Release controls are SSL-voiced for bus functionality, including the program-dependent Auto Release function. Conjure "barely a wiggle" 2-bus glue, or "bury the needle" full dynamic crush with the continuous Threshold control.

Custom Enhancements

New workflow features make the SSL G Bus Compressor Collection even more vital for the modern producer/engineer. The internal Side Chain Filter allows you precise tailoring of low frequency response to reduce low-end “pumping,” while the Mix control provides inline dry/wet processing — perfect for quick parallel compression on a drum or vocal bus. The Headroom control lets you adjust the overall operating level of the plug‑in.

Fade to Black

Just like the console units, the new SSL G Bus Compressor features the original Auto Fade feature, providing the signature SSL fade taper, up to 60 seconds. With the new SSL G Bus Compressor, plus the included DSP-lite SSL G Bus Compressor Legacy plug-in, you can craft your projects with Platinum‑selling sound.
