NEBULA - Brass



DiBiQuadro - Brass is an extremely powerful mixing EQ for Nebula 4 / Nebula 4 Player delivering full bottom end, smooth midrange, and beautiful top end. Middle bands provide bell shapes from surgical and narrow to wide and extensive. Low and high bands add wide bells and shelving curves for exceptional flexibility. Brass is a careful sampling of both active and transformer-balanced outputs of a vintage reminiscent hardware unit acclaimed for its great musicality. Dual-mode (12/18 dB/octave) High-Pass and Low-Pass filters complete the definitive arsenal of shaping tools.

Each band and preamp has been sampled without any converter / “calibration bias“ phase distortion. This allows overlapping the effect of more bands without adding unwanted coloration, reaching a new level of match with hardware for unparalleled results, even compared to the hardware itself. This methodology is named SP Tech.
