For decades, the SSL Bus Compressor has been the secret ingredient for top engineers and producers, the essential tool for making mixes sound bigger, fuller, and more powerful. It’s the legendary “glue” that brings a track together.
With The Bus+, Solid State Logic has engineered the ultimate and most versatile version of this iconic processor, combining its classic punch with an incredible array of modern sound-shaping tools.
More Than Just a Compressor
The Bus+ is built on the foundation of the original, celebrated circuit, but expands its capabilities exponentially. It can be clean and punchy like the SuperAnalogue™ 9000 Series, gritty and aggressive like an early 4000E, or deliver the over-the-top saturation needed for modern parallel drum processing. This isn't just a compressor; it's a complete analog processing powerhouse designed to be the final word in mix bus dynamics.
Four Modes of Operation: Go beyond traditional stereo processing. In addition to Classic Stereo and S/C Stereo modes, The Bus+ offers Dual Mono for processing two independent signals, or Mid-Side for unparalleled control over your stereo image.
Expanded Time Constants: New Attack and Release options, including the musical “Auto 2” setting, give you more flexibility to dial in the perfect compression character, from subtle glue to aggressive pumping.
Three Distinct Coloration Options: Combine these options to sculpt your tone. 4K Mode adds variable harmonic distortion for that vintage “grit” and “grunge.” LOW THD Mode cleans up the bottom end by reducing low-frequency distortion during compression. F/B Mode delivers a more “relaxed” compression style, perfect for gentler material.
Unprecedented Analogue Control
The Bus+ is engineered for the precision demands of modern workflows, especially mastering. Every knob is stepped and read by a microcontroller, translating its position into the exact circuit parameter. This innovative design not only makes recalling your settings effortless but also eliminates pot tolerances, ensuring that left and right channels are perfectly matched for flawless stereo imaging. It's the kind of accuracy that was once only possible in the digital domain, now available with pure analog warmth.
Built-in 2-band Dynamic EQ (D-EQ): This "intelligent" EQ changes gain in response to the signal level, allowing you to tame harsh frequencies only when they become a problem or enhance elements of your mix without affecting the overall balance. Place it before or after the compressor for ultimate flexibility.
Transient Expander: Add extra punch and impact to your drums or any other percussive element. The onboard Transient Expander lets you shape the attack of your signals for a sound that truly jumps out of the speakers.
Variable Sidechain HPF: A continuously variable High-Pass Filter on the sidechain, ranging up to 300 Hz, gives you precise control over how the compressor reacts to low-frequency information. This prevents your kick drum from causing unwanted pumping and helps maintain a solid low end.
Flexible Routing and Connections
The Bus+ is designed to be the central hub of your analogue processing chain, offering sophisticated routing options that seamlessly integrate with your existing setup. Whether you're working entirely in the analogue domain or in a hybrid environment, it provides the connections you need to get the job done efficiently.
Configurable Processing Order: Tailor the signal flow to your specific needs by choosing whether the Bus Compressor comes before (default) or after the D-EQ. This simple but powerful option opens up a world of creative processing possibilities.
External Side-Chain I/O: Use the dedicated inputs and sends to trigger the compressor with an external source. This is perfect for classic techniques like ducking or for creating complex rhythmic interactions between different elements of your mix.
Mix Control: The onboard Mix knob makes parallel compression instantaneous. Dial in the perfect blend of the compressed and uncompressed signal to add weight and punch while preserving the natural dynamics of your mix.
Legendary Compression Made Even Better
The Solid State Logic Bus+ is more than just an update to a classic; it's a complete reimagining of what a bus compressor can be. It offers the legendary SSL sound that has defined countless hit records, combined with a suite of advanced tools that empower you to push your mixes further than ever before.
