Solid State Logic 729740X2 - Fusion Analog Stereo Outboard Processor

Analog Stereo Processing for Modern Mixing and Mastering
The Solid State Logic Fusion is a 2U rack-mounted analog stereo processor designed to enhance the character, depth, and warmth of any mix or stem. Combining five carefully crafted analog circuits, Fusion offers a variety of sonic enhancements, from harmonic saturation and vintage EQ shaping to stereo widening and transformer-based coloration. Ideal for hybrid and traditional studio setups, Fusion delivers SSL’s renowned analog processing in a streamlined workflow, perfect for mix bus applications or stem processing.

Vintage Drive for Harmonic Saturation and Soft Compression
Fusion's Vintage Drive section introduces non-linear harmonic enhancement, allowing users to add warmth, cohesion, and character to their mix. The Drive and Density controls interact to create harmonic distortion and soft compression reminiscent of overloaded analog circuits. Whether used subtly for added punch or driven aggressively for rich harmonic coloration, this section provides a versatile tool for sculpting analog warmth.

Violet EQ for Musical Low and High Frequency Shaping
The Violet EQ section offers a two-band shelving equalizer with a selection of carefully chosen frequency points, drawing inspiration from SSL's legacy of musical and intuitive EQ design. With ±9 dB of gain available per band, this minimum phase-shift EQ delivers smooth tonal shaping, perfect for adding weight to the low end and enhancing the high-frequency presence of a mix without introducing harshness.

High-Frequency Compression for Smooth Top-End Control
The HF Compressor section of Fusion is designed to round off excessive high frequencies while maintaining a natural, transparent character. Modeled after the gentle attenuation found in classic analog tape machines, this compressor subtly tames harshness and adds a smooth, polished finish to the top end of a mix. It is an essential tool for modern productions, providing clarity and control over high-frequency content.

Stereo Image Enhancement for Expanding the Mix Width
The Stereo Image control offers a true analog Mid-Side circuit that manipulates the Side signal, allowing for subtle or dramatic adjustments to stereo width. Whether used to add spaciousness to a mix or to create a more focused center image, this feature provides a powerful tool for stereo enhancement. By carefully shaping the stereo field, it helps mixes feel wider and more immersive without sacrificing mono compatibility.

Transformer Circuit for Subtle Low-End Saturation and High-Frequency Sparkle
Fusion’s Transformer section introduces SSL’s custom-designed transformer circuit, adding subtle harmonic enhancement to both the low and high frequencies. This feature thickens the low end while introducing a gentle high-frequency phase shift, resulting in a fuller, richer sound. Engaging the transformer imparts the unmistakable analog depth and character that SSL is known for, making it an invaluable tool for final mix processing.
