Know before you buy
While it retains the authentic circuit of the original, THE BUS+ adds significant versatility through four operation modes, including Mid-Side and Dual Mono. It also integrates a 2-band Dynamic Analogue Equalizer (D-EQ) and offers switchable coloration modes like 4K and LOW THD for more sonic flexibility.
Yes. The unit features stepped, digitally controlled analog pots, which allow for precise recall and repeatable settings essential for mastering environments. The addition of Mid-Side processing also makes it a powerful tool for stereo bus enhancement.
The 4K Mode introduces variable harmonic distortion to the signal path. It is designed to emulate the gritty, punchy character of the classic SSL 4000E console, adding warmth and saturation to your mix.
Yes, it includes dedicated XLR inputs for external side-chain signals and sends. This allows you to trigger the compressor using an external source, such as a kick drum, for precise ducking or pumping effects.
The D-EQ is a 2-band processor that applies compression or expansion based on the frequency content of your audio. It allows you to tame harsh frequencies or boost low-end punch dynamically without affecting the entire signal spectrum.
The F/B mode changes the compressor's detection circuit to a feedback topology, resulting in a more relaxed, musical, and less aggressive compression character. It is ideal for smoothing out signals while maintaining natural dynamics.
