The Solid State Logic Bus+ Stereo Buss Compressor is a new 2U rack unit that builds on the original bedrock design of the Bus Compressor, which first appeared on SSL's 4000 B console in 1976. Remaining faithful to the original circuit design, THE BUS+ features 2181 THAT VCA's in its audio path and offers the classic time constants and compression ratios which have glued records together for over four decades. Analyzing feedback from key-users and looking at modern production workflow, including how the plug-in equivalents are being utilized, several new processing tools and sonic colouration options feature on THE BUS+ including, four modes of operation: Classic Stereo, Σ S/C Stereo, Dual Mono and Mid-Side, and three distinct compression colours: LOW THD, F/B and 4K MODE. New time constant settings, including ‘Auto 2’ and compression ratios are also added to the THE BUS+ to create ‘the compressor package’.
