Solid State Logic Bus+ 2-Channel Bus Compressor & Dynamic Equalizer

Solid State Logic Bus+ 2-Channel Bus Compressor & Dynamic Equalizer

For South African mixing engineers chasing that legendary “glue,” the SSL Bus+ compressor from Marshall Music puts the iconic SSL bus compression sound — refined and expanded — into a 100% analog 500-series-style unit. Built around premium 2181 THAT VCAs and stepped, digitally controlled front-panel pots for total recall accuracy, the Bus+ takes the classic G-series bus compressor and adds a powerful dynamic EQ section for even more mix-bus shaping.

What Makes the SSL Bus+ Compressor a Mix-Bus Essential

At its core, the SSL Bus+ compressor offers four operating modes — Classic Stereo, S/C Stereo, Dual Mono, and Mid-Side — giving you the flexibility to apply that signature SSL glue across a full mix, individual stereo elements, or width-specific processing. A comprehensive set of attack times from 0.1ms to 40ms, combined with new release options including the innovative “Auto 2” setting, means you can dial in everything from fast, punchy drum bus compression to slow, transparent mix-bus levelling.

Beyond compression, the built-in D-EQ adds a 2-band analog dynamic equalizer directly into the signal path, letting you tame problem frequencies dynamically without reaching for a separate EQ. In addition, internal and external sidechain inputs come with a variable highpass filter, a hidden transient expander, and a parallel compression mix knob — so you can blend heavily compressed and uncompressed signal to taste.

What truly sets the Bus+ apart, however, is its set of three distinct compression colouration modes. 4K Mode introduces variable harmonic distortion reminiscent of the SSL 4000 console, LOW THD Mode reduces low-frequency distortion for cleaner results, and F/B Mode alters the compression characteristics for a more relaxed, musical feel. As a result, one unit covers an enormous range of mix-bus tones, from aggressive and punchy to smooth and vintage.

Whether you’re gluing together a full mix, processing drum buses, or shaping stereo elements with mid-side control, the SSL Bus+ compressor delivers the console-grade sound that built SSL’s reputation. Order yours today from Marshall Music, South Africa’s home for Solid State Logic gear.

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.
