Subharmonic Synthesizer - 500 Series

For decades, dbx’s patented Subharmonic Synthesis has rattled foundations enhancing the bass in a variety of professional applications including nightclub and DJ mixing, theatre and film sound, music recording, live music performance and broadcasting. dbx’s Subharmonic Synthesis process actually produces a new, Waveform Modeled bass note, exactly an octave below the bass in the original audio. The dbx 510 answers the call of audio professionals everywhere delivering Subharmonic Synthesis in the convenient design of a 500 Series module. The 510’s two separate bands of subharmonic synthesis provide the best combination of smoothness and control, while the independent Low Frequency Boost circuit is designed to get the most out of high-performance, low frequency speaker systems. Unlike other attempts at bass synthesis, the dbx process produces musical low frequencies that don’t interfere with mid and high-band information, even when the maximum synthesis and boost are applied. The result is a low-end punch that people really feel! Put some boom in your room with the dbx 510!
