God damn training video.. this boys complicated asf. That part about pre emphasis and deemphasis had me lost. I like it in my rig but actually have it right before a multi effects unit.cthe dsp 256 xl. also a rane sp15 eq and dbx 166 before it. It feels like the compressor and limiter work together somehow

Pre / de emphasis is used in broadcasting (and also analog tape). It's basically just a big boost in the high end (pre emphasis) and then an equal cut in the high end (de emphasis). It's used to lower the hiss. When American terrestrial FM radio stations send their signals from their transmitters, they boost the high end by 17dB. The de emphasis is then applied in people's radios. That way the noise of FM transmission is reduced by 17dB while leaving the program material sounding flat, or un-EQ'd. If you can find pictures of old audio cassettes, you will see on some of them that normal bias cassettes (Type I) has 120 μs (microseconds) written on them and chrome and metal cassettes (Type II and Type IV) have 70 μs written on them. Those values correspond to how much pre emphasis is applied. Type I tape cannot handle as much level without distortion so the pre emphasis starts at a lower frequency and takes longer to reach its maximum, resulting in a 12dB boost at 15kHz. Type II and IV can handle more level so the pre emphasis starts at a higher frequency and takes less time to reach its maximum resulting in a 14dB boost at 15kHz. Professional multitrack tape on the other hand uses treble and bass boost curves for their pre and de emphasis and isn't expressed like it is with cassettes.
