A sub-harmonic synthesizer classically used in the live environment to generate infra (lower than 36Hz) and sub bass (36-70Hz) from weaker bass programme. It features very low distortion and sophisticated filtering stages. Independent control of the two frequency spectrums helps preventing speaker damage and dealing with resonant acoustics or speaker resonance with LF cabinet porting. The meters are peak detecting from both Left and Right signal paths.
BEWARE: extreme care is needed. Driving high infra bass levels into insufficient speakers can lead to speaker equipment damage.
