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.
