The Bus+ 2-Channel Bus Compressor and Dynamic Equalizer from SSL combines the legendary sound of their bus compressor with innovative features for crafting your sound. The Bus+ has four flexible modes—Clean, Grit, Drive and Crush—that provide distinct compression flavors from transparent to heavily saturated. A dynamic equalizer lets you shape the tone with surgical precision. A transient expander adds punch and impact. High-grade components like THAT 2181 VCAs deliver premium analog sound. Comprehensive connectivity and routing options allow for complex signal flows.

Four Modes Offer Signature SSL Sound

Whether you want clean, transparent compression or an aggressively distorted tone, the Bus+ has a mode for you. Clean mode provides SSL's renowned bus compression effect with a pristine, natural sound. Grit introduces harmonic distortion for an edgy quality. Drive increases the distortion for an saturated, in-your-face tone. Crush maximizes the distortion for an smashed, speaker-shredding effect that is perfect for parallel drum or synth processing.

Dynamic Equalizer Shapes the Tone

The Bus+ includes an innovative dynamic equalizer that lets you shape the tone with precision. Six bands—low shelf, low-mid bell, mid bell, high-mid bell, high bell and high shelf—cover a wide frequency range. You can apply up to 6dB of cut or boost to each band. The equalizer is dynamic so the amount of EQ is proportional to the signal level. This allows you to, for example, tame resonances that become more prominent as a source gets louder without dulling the tone at lower levels.

Transient Expander Adds Punch

A built-in transient expander lets you add punch and impact to signals. The expander uses an envelope follower to detect transients in the signal—the fast, high-energy peaks. It can then amplify just the transients for more attack and definition. This is perfect for adding snap to drums, tightening up the low end of a bass or increasing the pick click on a guitar. Combined with the compression and distortion in the Bus+, the transient expander allows for aggressive tonal shaping.

Premium Components and Maximum Connectivity

The Bus+ is built from high-quality components for outstanding analog performance. It uses THAT 2181 VCAs in the audio path and has a fully discrete signal chain with high-grade op amps. Comprehensive connectivity options include balanced XLR and TRS inputs and outputs; sidechain insert points; and link jacks for connecting multiple units. The Bus+ gives you the premium SSL sound with modern features and maximum flexibility.
