dbx uses a single frequency pre-emphasis system, whereas Dolby uses four separate pre-emphasis amplifiers, each for a different frequency band. Since tape hiss is primarily a problem for high-frequency sounds, Dolby uses much stronger pre-emphasis at high frequencies than low.
What is DBX Dolby?
Dbx and Dolby endeavored to reduce noise using purely electronic designs. Dbx compresses the source (in the recording studio) so it has less dynamic range, then decompresses it so tape hiss is obscured. Dynamic compression, as used by dbx, mutes loud sounds and amplifies soft ones. This reduces signal amplitude.
