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.

Key features

Bus Compressor
4 modes of operation - Classic Stereo, Σ S/C Stereo, Dual Mono or Mid-Side
External side-chain inputs and sends
The authentic SSL Bus Compressor circuit
LOW THD Mode reduces low-frequency distortion caused by compression
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
New Attack and Release options, including the new 'Auto 2' setting
MIX control for instant parallel compression
Moving-coil gain reduction meters
Unlockable Transient Expander

D-EQ

Powerful 2-band analogue Parallel Dynamic EQ - the D-EQ
Compress/Expand modes
3 choices of time constants for each band - Nominal, FAST or AUTO
16 selectable Frequency points per band
Adjustable Range control per band from 0.5 dB to 15 dB
HF band can be switched to Bell shape, with selectable frequencies covering High-Mids and Highs
Frequency band static 'make-up' gain for LF and HF bands (Stereo/ Σ S/C Stereo) or LF band (Dual Mono/Mid-Side)
G-Series mode changes LF filter to be 2nd order with degree of undershoot/overshoot
Tri-colour activity LEDs to indicate D-EQ activity
Individually bypass-able bands
