For over three decades, dbx’s patented Subharmonic Synthesis has redefined bass reproduction in professional audio. The dbx 510 SubHarmonic Synthesizer delivers deep, powerful low-end in a convenient 500 Series module, making it ideal for nightclubs, DJs, theatres, live performances, studios, and broadcasting.

Unlike traditional EQ or bass enhancement tools, the 510 doesn’t just boost existing low frequencies—it creates a new waveform-modeled bass note one octave below the original input. This innovative process ensures a musical, punchy low-end that doesn’t muddy mid or high frequencies, even at maximum settings.

The 510 features two independent subharmonic synthesis bands for precise tonal control, along with an independent Low Frequency Boost to maximize performance from high-end low-frequency speaker systems. Synthesized frequency level indicators and a simple, intuitive interface make operation quick and straightforward, giving you complete control over your low-end sound.
