For many years, dbx's patented Subharmonic Synthesis has been the foundation for enhancing low frequencies in a wide range of professional applications including nightclub and DJ mixing, theater and film sound, music recording, live music performance, and broadcasting. Dbx's Subharmonic Synthesis creates a new, wavelike modeled frequency that is exactly one octave below the lowest frequencies of the original signal. This can be used to create a wide variety of interesting effects: enhance thin bass drums in music production, help weak synthesizers or drum machines get going - if necessary, until the cups fall out of the cupboard! Make your sound effects for cinema and theater sound really noticeable or get everything out of your PA system.
The dbx 510 is based in principle on the circuitry of the legendary DBX 120 A and makes it available in the convenient design of a 500 module. The two separate bands of subharmonic synthesis offer an ideal combination of smoothness and control. The independent low frequency boost circuitry is designed to get everything out of a powerful subwoofer. Unlike other bass synthesis techniques, the dbx circuit produces musical low frequencies that do not affect mid and high band information, even when maximum synthesis and boost are applied. The result is a low frequency punch that the audience really feels!
