Solid State Logic BUS+ Bus Compressor – Preorder

An Updated Legend – The Solid State Logic BUS+ Bus Compressor

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 colors: LOW THD, F/B and 4K MODE. Each color offers a different characteristic and can be combined for very unique compression styles.

General

• 100% analogue circuit, controlled digitally using stepped front-panel pots
• Huge +27.5 dBu headroom
• Configurable processing order – Bus Compressor pre D-EQ (default) or post
• CH 1 IN and CH 2 IN buttons for global bypass
• Settable Operating Level – 0 dB (nominal), +10 dB, -5 dB
• Sleep and Auto-Sleep modes
• Precision MDAC-controlled MAKE-UP Gain with two ranges – 1 dB or 0.5 dB steps

Bus Compressor

• Four modes of operation – Classic Stereo, 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
• Three 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/ 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-color activity LEDs to indicate D-EQ activity
• Individually bypass-able bands
