The Solid State Logic THE BUS+ is a professional-grade 2-channel bus compressor and dynamic equalizer designed for mastering and mixing applications. This dual-function processor combines transparent compression with surgical EQ control, allowing you to shape and glue your stereo mix with precision. The compressor section delivers smooth, musical compression ideal for controlling dynamics across your entire mix without sacrificing clarity. The integrated dynamic equalizer provides four bands of parametric EQ that respond intelligently to your audio, enabling both corrective and creative processing. Built with SSL's legendary analog circuitry and modern digital control, THE BUS+ offers intuitive operation with comprehensive metering and recall capabilities. Perfect for professional studios, broadcast facilities, and mastering engineers seeking transparent yet powerful bus processing.
- Authentic, 100% analog circuit, controlled digitally using stepped front-panel pots
- Four modes of operation—Classic Stereo, Stereo (with summed sidechain), Dual Mono, or Mid-Side
- Huge +27.5 dBu headroom and selectable operating level (0, +10, or -5 dB)
- External sidechain inputs and sends
- Configurable processing order; put the Bus Compressor before or after the D-EQ
- Global bypass, clipping indicators, and manual/automatic sleep modes
- 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's single-VCA operation with variable harmonic distortion brings grit and grunge
- Negative ratios allow for creative pumping effects and control of particularly loud signals
- New attack and release time constants including an additional auto setting
- Precision MDAC-controlled make-up gain in coarse (1 dB) or fine (0.5 dB) steps
- Variable sidechain high-pass filter control up to 300 Hz in 10 Hz steps
- Moving-coil gain reduction meters
- Compress/expand modes with three choices of time constants for each band
- 16 selectable frequency points per band
- Adjustable range per band from 0.5 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 (in Stereo or Summed S/C Stereo) or LF band (in Dual Mono or Mid-Side)
- G-Series mode changes LF filter to be second order with degree of undershoot/overshoot
- Tricolor activity LEDs to indicate D-EQ activity
- Per-band bypass
