DBX 120A Subharmonic Processor features Modeled Waveform Synthesis which produces a new Waveform Modeled bass note, exactly an octave below the bass in the original audio to give you a much fuller bass sound. DBX-120A has an independent Low Frequency Boost circuit that is designed to get the most out of high-performance low frequency speaker systems. 120A also features both 1/4 inch jack and RCA input connectors, along with main outputs which can be full range (including synthesis) or high frequency only, along with a separate subwoofer output with its own level control.
DBX 120A Subharmonic Processor's flexible system interfacing is achieved via a patented subharmonic synthesis process that actually builds the synthesized waveform using the waveshape of the original bass material. Unlike other attempts at bass synthesis, the dbx process produces smooth, musical low frequencies that don't interfere with mid and high-band information, even when maximum synthesis and boost are applied. The result is a low-end punch that people really feel, even at system levels that won't destroy sound equipment or damage hearing.
