1) _{“n” means “1”, “2”, “3”, or “4”; “s” means “L” or “R”; “p” means “M” or “A”}
2) _{EIM refers to 75-µs Equivalent Input Modulation. It is defined as the audio-signal level which results in a stated percentage modulation,}
when the DBX encoding process is replaced by a 75-µs preemphasis network.
