I've heard guys talking about dialing in for specific rooms, is this what they are referring to using to achieve such desired results? How can you tell which frequencies need to be cut or boosted based upon the room?
Yes, a semi-parametric mid is very useful for that. You kind of have to use your ear. For example, if you are on the floor of a big gym type venue (big open sound), it sometimes helps to boost the low mids (100hz-200hz) versus the bass control to clarify the low end. If you are playing on a raised hollow wooden stage which often causes the low end of a bass to boom and sound mushy, cutting in the 200-300hz region can often help).
Another example... if you are playing in a smaller room with lots of drapes, carpets, etc. that tend to eat up the top end of the sound, a slight boost around 1K or 2K can bring the brightness back a little bit.
No wrong or right answers, each room is different. Just remember that the term 'equalization' was really driven by the goal of keeping a rig sounding the same in different rooms... to keep the inherent tone you like sounding relatively the same from room to room.
Edit: When I owned my Eden WT heads with those multi-band semi-parametric section, the only thing I ever used that EQ for was slightly boosting or cutting low mids with the lowest band based on room acoustics. So, I hear what you are saying. Those are very nice heads, voiced very nicely for many players' tone goals right out of the box.
