Solid State Logic Fusion & Bus+ Bundle

Solid State Logic Fusion & Bus+ Bundle

The Solid State Logic Fusion & Bus+ Bundle pairs two of SSL's most acclaimed hardware outboard processors into a complete, professional analogue mix bus chain — combining the multi-tool colour and enhancement capabilities of the SSL Fusion with the legendary VCA compression architecture of the SSL Bus+, all in a four rack-unit package that brings genuine SSL console bus processing to any studio, large or small. Together, these two units represent the heart of a professional analogue mastering and mix bus signal chain: the Bus+ providing the transparent, musical glue compression that has defined commercially released recordings for decades, and the Fusion delivering harmonic saturation, precision EQ, stereo imaging, and transformer colour to complete the picture. Whether you are working in a professional mix suite or a project studio, this bundle provides a level of analogue signal processing quality that was previously available only in the most expensive console-equipped facilities.

SSL Bus+: Next-Generation G-Bus Compression with Dynamic EQ and Four Operating Modes

The SSL Bus+ is Solid State Logic's most advanced hardware bus compressor — a direct evolution of the SSL G-Series bus compressor circuit that has appeared on more commercially released recordings than virtually any other piece of analogue outboard equipment in history. At its core are THAT 2181 VCA chips, chosen for their low distortion characteristics and wide dynamic range headroom of +27.5dBu, preserving the transparency and punch of the original circuit while extending its technical performance. Four operating modes — Classic Stereo, Σ S/C Stereo, Dual Mono, and Mid-Side — provide flexibility that goes far beyond the original G-Bus design, allowing the Bus+ to function as a dual mono compressor on individual stems, an M/S compressor for stereo width management, or a classic linked stereo bus compressor. Three compression colouration options — LOW THD for maximum transparency, F/B (Feedback) for a more relaxed, vintage character, and 4K Mode for variable harmonic distortion reminiscent of SSL's 4000-series console — give the Bus+ a range of tonal personalities within a single unit. In addition, a built-in two-band Dynamic EQ, Transient Expander, high-pass filter sidechain (up to 300Hz in 10Hz steps), new Auto 2 attack and release settings, and negative ratio options for creative pumping effects make the Bus+ far more than a vintage compressor recreation — it is a thoroughly modern, deeply capable bus processing tool.

SSL Fusion: Five Stages of Analogue Enhancement in a Single 2U Processor

The SSL Fusion is Solid State Logic's answer to the question of how to add depth, weight, and dimension to a digital mix without resorting to obvious saturation or colouration. Five distinct processing stages operate independently or in combination — providing a level of tonal sculpting that no single-purpose outboard processor can match. Vintage Drive introduces SSL's proprietary non-linear harmonic enhancement circuit, adding cohesion and harmonic richness to a mix at the level of detail that transforms it from a collection of individual stems into a unified, organic whole. The Violet EQ is a two-band minimum-phase shelving equaliser with four switchable frequency points per band and ±9dB of attenuation, designed for efficient, musical tonal balance rather than surgical correction. The HF Compressor provides high-frequency dynamic control — smoothing harshness and sibilance from the top end of a mix with a gentle, programme-dependent character. The Stereo Image section offers true analogue Mid-Side processing, manipulating the Side signal for width enhancement, narrowing, or spatial focus. Finally, the SSL Transformer stage routes the mix signal through a custom-designed SSL output transformer, adding the subtle harmonic and phase character that defines the sonic signature of SSL console output stages. A switchable high-pass filter (30, 40, or 50Hz) and input/output trim controls (±12dB each) complete the Fusion's signal management capabilities. As a result, the Fusion functions simultaneously as a tonal enhancement tool, a stereo image processor, and an analogue transformer stage — all in 2U. Available at OneStopMusic South Africa, the Solid State Logic Fusion & Bus+ Bundle is the definitive two-box analogue mix bus solution for South African engineers who demand SSL quality at every stage of the signal chain.

Solid State Logic

Founded in 1969 by Colin Sanders, Solid State Logic began life building switching systems for pipe organs before evolving into the world's leading manufacturer of analog and digital audio consoles. SSL pioneered industry-defining technologies — including motorized fader automation and total recall of mixer settings — and its large-format consoles became the backbone of major recording, broadcast, film, and live sound facilities worldwide, shaping the sound of countless hit records.

In recent years SSL has brought that console DNA into the personal and project studio space, with a range of award-winning audio interfaces (SSL 2, SSL 2+, SSL 12, SSL 1), compact mixers, control surfaces, channel strips, and processing plug-ins. Renowned for high-bandwidth, low-distortion signal paths and the iconic "SSL sound," the brand remains a benchmark name across professional and home studios alike.
