The SSL Fusion is a 2U analog rack processor designed for stereo bus and mix bus use. It combines five separate circuits in a single unit: a high-frequency equalizer, an input transformer, a high-frequency compressor, a stereo image processor, and a harmonic drive stage. Each circuit can be used independently or in series. The plugin bundle models each of the five circuits separately, allowing them to be applied to any bus or channel without the full hardware chain.

Plugin breakdown

The Violet EQ models the Fusion’s high-frequency equalization circuit. It operates above 1kHz as a two-band passive-style equalizer, adding air to vocals, instruments, and buses without introducing the harshness that can appear at the top end of digital linear-phase EQs. The Fusion Transformer models the input transformer saturation characteristic, adding harmonic distortion and low-frequency thickening from the transformer-coupled signal path.

The HF Compressor applies frequency-selective compression in the high-frequency range, useful for controlling brightness and sibilance without affecting full-spectrum dynamics. The Stereo Image plugin models the Fusion’s M/S width circuit, expanding or contracting the stereo field with controls over the mid and side balance. The Vintage Drive adds transformer-style harmonic saturation across the full frequency range, with drive and character controls for adjusting the harmonic density.

The Fusion Bundle suits producers who want analog bus processing character across multiple stages. The five plugins work well together on a mix bus chain or independently on individual stems. The Vintage Drive and Fusion Transformer are particularly useful for adding warmth and harmonic density to digital productions. The Violet EQ is a solid high-frequency tool for mastering-style bus work. Each plugin is available separately on Plugin Boutique; at $75 for all five, the per-plugin cost works out to $15.
