Product Description

The dbx 120A Subharmonic Synthesizer: Why just rock the house when you can rattle the foundation loose!
For decades, the patented dbx Subharmonic Synthesis has been the secret weapon used by mobile DJs and film & sound professionals to produce amazing impact. The dbx process actually produces a new, Waveform Modeled bass note, exactly an octave below the bass in the original audio. Its two separate bands of bass synthesis provide the best combination of smoothness and control. Low Frequency Boost helps you get the most out of high-performance low frequency speaker systems. Flexible I/O includes 1/4" and RCA inputs, main outputs which can be full range (including synthesis) or high frequency only, and a separate subwoofer out with its own level control.

dbx 120A Subharmonic Synthesizer Features

  • Individual control for two ranges of subharmonic frequencies
  • Separate Low Frequency Boost Circuit
  • Separate Subwoofer Output
  • 1/4" Balanced inputs and outputs
  • RCA Input Connectors
  • Front panel LEDs that show crossover status and synthesis activity
  • Patented circuitry ensures that mid and high frequencies are not affected
  • Built-in crossover with choice of 80Hz or 120Hz crossover point
  • Enhance bass audio material for use in a veriety of professional applications such as:
    • Nightclub and dance mixing
    • DJ Mixing
    • Theater and Film Sound
    • Music Recording
    • Live Music Performance
    • Broadcasting

Flexible system interfacing is achieved by providing both 1/4" 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.

The 120A'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 equipment or damage hearing.
