In reference to a board with a master eq. Start with the upside down smile, or frown. The peak, or mid frequencies of the smile are at zero. Zero being the midline between positive and negative. You would be cutting the furthest lows and furthest highs completely most likely. That’s a proper pa eq setting. All individual channels can be tweaked afterwards. A little will go a long way.
I have to disagree with this. There is no one preconceived EQ curve that is correct. If you just lose the lows and highs, you end up with a midrange-y nasal sound that hurts more than it sounds good. No Phil bombs happening with that curve nor any clean, crisp cymbals or vocals.
By the mid to late 70s, they were getting really good at tuning the PA to the room using pink noise and measurement tools. In 1984, Meyer developed SIM (Source Independent Measurement) which compared the output of the desk to what was coming out of the speakers in real time so that they could make that as perfect as possible, using whatever EQ settings were necessary with their CP10 complementary phase EQ. By the 90s, the system was really tweaked nicely.
But throughout the years, they spent an immense amount of effort and money in making sure that every link the chain was just exactly perfect. By the mid 80s, the entire system was DC coupled, meaning that there were no capacitors in the signal path until it hit the power amps. No caps means minimal phase shift which means maximum intelligibility (again, see the CP10, which minimizes phase shift while providing very precise EQ).
Also, if you are referring to the 90s, putting the band on IEMs and having no speakers on stage allows for extremely clear vocals because there's no garbage from monitors or amps or other leakage coming through. That makes a huge difference.
Also, playing in a large room has challenges but it's nothing like the challenges in a small club with low ceilings and a loud band. Getting clear vocals in that scenario is a true battle. Theaters are a bit better, perhaps the sweet spot.
You can't really achieve what they did without putting in the time and money.
