User manual DBX 120XP

[. . . ] ¨ MAX SYNTHESIZED FREQUENCY The disco boom of the 70Õs was fueled by the throbbing bass beat of dbx Subharmonic Synthesizers in discos around the world. During the 80Õs, patented dbx Subharmonic Synthesis was the secret weapon used by mobile DJÕs and film and sound professionals to produce an impact unavailable from any other deviceÑunique because the dbx process actually produces a new, Waveform Modeledª bass note, exactly an octave below the bass in the original audio. [. . . ] The result is a low-end punch that people really feel, even at system levels that won't destroy sound equipment or damage hearing.
