Because dbx Type I and Type II are broadband ( single-band ) companders ( unlike Dolby-A's four bands ), they are susceptible to audible noise modulation and other artifacts.
2.
This causes the compander to'back off'the gain in certain circumstances and reduce the audibility of noise modulation even with this pre-emphasis, noise modulation can become audible when using very noisy media to begin with, such as the Compact Cassette format.
