    • Solid State Logic THE BUS+ Bus Compressor

Manufacturer's Description from SSL

We've been on a mission to create the ultimate and most versatile incarnation of the Bus Compressor ever. The bedrock of the design remains faithful to the original circuit and using this as the foundation, we've built upon it, adding several unique colouration options and advanced processing tools. If you need it to be clean and punchy like the SuperAnalogueTM 9000 Series version, it can be. If you need it to be gritty and grungy like an early 4000E, it can do that also. Or if you need over-the-top, saturated, parallel compression for the drums, THE BUS+ has got you covered.

THE BUS+ circuit design utilises high-grade components, including 2181 THAT VCAs for superior analogue performance, four modes of operation and 3 distinct compression colouration options which can be combined to perfectly suit the genre you’re working on. THE BUS+ also packs in sophisticated routing options and advanced processing tools: Dynamic Equaliser (D-EQ), Transient Expander and so much more…

 

Advanced processing tools

Whilst the core design of THE BUS+ remains faithful to the original, a number of advanced processing tools have been added to create the most versatile Bus Compressor ever. In addition to D-EQ and Transient Expander, THE BUS+ features three unique compression colours; LOW THD, F/B and 4K MODE. Each ‘colour’ offers a different characteristic and can be combined for very unique compression styles.

LOW THD MODE introduces a special circuit modification in the side-chain, helping to limit the amount of low frequency distortion compression can create, especially with fast release times. Subjectively, LOW THD 'cleans up' the bottom-end, allowing you to achieve 'cleaner' gain reduction.

F/B (FEED-BACK) MODE takes the signal feeding the side-chain from a feed-back position (i.e. after the main gain-reduction VCA in the audio path). This results in a more 'relaxed' style of compression, in contrast to the traditional 'grab' of the Bus Compressor.

4K MODE changes the operation of the VCA from balanced to unbalanced (matching how the Bus Compressor in a 4000-series console was implemented). It also introduces a variable amount of harmonic distortion via the VCA. These two factors combine to allow for a more 'coloured' sound. THE BUS+ allows you to adjust the distortion amount which 4K MODE offers. You'll find there's a certain 'sweet spot' (depending on your mix level) in which your material will become more cohesive, thanks to the added thickness.

 

D-EQ

After a considerable amount of research and development, we are proud to introduce the first ever SSL Dynamic EQ (the D-EQ) as part of THE BUS+. The side-chain is a specially adapted version of the Bus Compressor side-chain with additional circuitry such as the gain reduction limiter for the Range parameter. We think the D-EQ is every bit as musical and powerful as the Bus Compressor itself. The D-EQ can enhance the top and bottom end of your mix with ease, making it an extremely powerful companion alongside the Bus Compressor. 

The D-EQ is a 2-band parallel Dynamic EQ. Each band has 16 frequency points to choose from, allowing complete control over which part of the frequency spectrum you want to affect. The High Frequency band can also be changed from a shelf filter to bell curve.

Compression / Expansion: Each band has a 31-position stepped control labelled with COMP and EXP at the extremes of the control. As you turn the control clockwise from the centre position '0' (no effect), you start dialling in an expansion effect. Moving the control anti-clockwise, you start dialling in a compression effect.
