I ran an LP mastering operation for about 12 years FWIW I'm not making this up or blowing smoke. ![]() There is good information in the article you linked and misinformation as well.Īll stereo LP mastering systems employed RIAA pre-emphasis. Tone controls were not on preamps to correct LPs! There is a reason so many preamps made in the US today don't even bother, and yet those early stereo LPs sound just fine on them. I've seen this problem a lot, having put myself through an engineering program by being a service technician- I've worked on literally hundreds of turntables and owned dozens of cartridges.Ĭlick to expand. IMO this is one of the weaknesses of vinyl people don't seem to realize that the suspension is ephemeral. I've been able to revitalize older cantilevers (if they got stiff rather than collapsing) by using a tiny amount of brake fluid, but that stuff can take paint off so you have to be really careful and patient with it (the cartridge has to lay on its back for a few weeks) to make sure it can't migrate down the cantilever and contaminate the stylus! Its only when you get a new cartridge set up properly you realize how degraded the old one got. Of course this degradation occurs so slowly that you don't notice if over time. There's no cartridge ever made where that could be true except perhaps a Decca and that's on account of it having no cantilever. That means that on a typical 31-band graphic EQ, you’d need to use five or more bands to approximate a shelving boost at 5 kHz!Įach slider has it’s own narrow range of action, so instead of a gentle sloping curve to a flat shelf, the overlapping edges of each band create noticeable peaks and troughs.Uh, no, you don't, unless the stylus was recently replaced. To approximate a shelving filter with a graphic EQ, you’d have to adjust every single band on the other side of the corner frequency. You can think of them like the treble and bass controls on a car stereo. They’re typically used to broadly adjust the highs or lows to taste. ![]() Shelving filters are a basic EQ type for boosting or attenuating material above or below a corner frequency. Parametric EQ gives you access to a much wider range of shapes and curves using far fewer bands than graphic EQ.įor example, consider a shelving filter like the type you’ll find on the Empress ParaEQ MK II Deluxe. On top of that, it provides specific advantages for guitar players. However, parametric EQ is much more flexible once you get used to it. This is the reason for the name ‘Graphic EQ.’ Some users find graphic EQ easier to learn at first since adjusting multiple bands creates a visual representation of the overall curve.
