The Smart Research C1 & C2 take the infamous SSL Bus compressor and gives it some gentle (and not so gentle) enhancements. Premier for drum bus and loop compression and for other sub-mix bus applications it offering SSL sound ‘punch’ and glue as well as adding a sweet, smooth radio polish on top.

Smart Research was formed by Alan Smart who has worked in the professional audio industry for 20+ years, including working at at SSL's 'Huge' studios in Oxford which led to a position as commissioning and service engineer for many years before going on to form Smart Research. 

 

This Smart Research C-Series compressor houses two independent mono compressors, providing independent control to also give true stereo operation. The C Series comprises of C1 and C2 models, with C1 being the predecessor of the other. Both provide desirable musicality and are suitable for both gentle applications as well as exaggerated compression effects, making it an extremely versatile unit. 

 

Often compared to the SSL G Series Bus Compressor in performance and tone shaping, the C1 and C2 have a characteristic sound that arises from the fast response at the onset of compression, and enable transients to still pass when delayed to a medium attack time. This can be used across a mix, or with any dynamic program, adding ‘punch’ and enabling sidechains to breathe around these transients while still being able to control overall levels.  

The C2’s CRUSH mode has been developed as an extension of this 'musicality' and is capable of exaggerated compression effects in conjunction with faster limit settings which make C2 less gentle wider than the C1, proposing use for a wider use of application.
