If there is a single piece of analogue processing equipment that is synonymous with SSL, it must be the SSL Bus Compressor.

From the very first commercially released SSL 4000B console in 1976, the Bus Compressor has always been the stalwart of the console centre section.

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.

Key features:

Bus Compressor:

- 4 modes of operation - Classic Stereo, Σ S/C Stereo, Dual Mono or Mid-Side

- F/B Mode alters the compression characteristics for a more 'relaxed' style of compression
- 4K Mode - single VCA operation with variable harmonic distortion to bring some 'grit' and 'grunge' to the mix
- Negative Ratios - for creative pumping effects and control of particularly loud signals
