dbx 120A 激励器



Subharmonic Synthesizer



Produces a new bass note exactly an octave below the bass in the original audio.



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 in. 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.
