The SSL Fusion is an all-analogue 2U stereo outboard processor for the modern hybrid studio, built to add real analogue tonal character, weight, and space to a mix bus or stereo stems. The SSL Fusion has 6 different modes for plenty of tone shaping options. Six Colours Vintage Drive: non-linear saturation, from subtle glue to heavier overdrive for that analog overload sound you get from pushing vintage equipment into the sweet spot Violet EQ: 2-band shelving EQ perfect for adding low-end weight and gorgeous high-end air on your mixbus, 4 fixed frequency points per band with ±9dB boost/cut HF Compressor: compresses only the top end, smoothly tames harshness and sibilance Stereo Image: true Mid/Side processing with width and space controls for wider mixes and more depth Transformer: custom 600Ω SSL transformer, adds subtle low-end harmonics and top-end sparkle LMC: full-band Listen Mic Compressor mode, unlocked by holding the HF Compressor button for 5 seconds Each circuit switches in or out independently to compare with and without. A stereo insert point (switchable to Mid/Side mode) lets you patch in outboard gear like the SSL Bus Compressor, positioned pre or post the Violet EQ or Stereo Image controls depending on mode. ±12dB Input and Output Trim controls handle gain-staging, and a master bypass switch offers a full bypass or one that keeps the input trim active.
