A Harman International Company

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 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 120XPÕs 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.
