DBX 120XP Sub Harmonic Synth (Used)

The disco boom of the 70’s was fueled by the throbbing bass beat of dbx Subharmonic Synthesizers in discos around the world. During the 80’s, patented dbx Subharmonic Synthesis was the secret weapon used by mobile DJ’s and film and sound professionals to produce an impact unavailable from any other device—unique because the dbx process actually produces a new, Waveform ModeledTM bass note, exactly an octave below the bass in the original audio.

The dbx 120XP Subharmonic Synthesizer has been specially optimized by dbx engineers for the needs of audio pro- fessionals. Its two separate bands of bass synthesis provide the best combination of smoothness and control, and the independent Low Frequency Boost circuit is designed to get the most out of high-performance low frequency speak- er systems.

Flexible system interfacing is achieved by providing main outputs which can be full range (including synthesis) or high frequency only, along with a separate subwoofer output with its own level control.

The 120XP’s patented subharmonic synthesis process 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 equip- ment or damage hearing.
