No the first 15 rows or so will be the cleanest sound area for omni recording. This is where the Pa. tends to be the loudest and least amount of Boom and the least directionality. This is where you find the most amount of people in the sweet spot. Once you get further back that is where you are dealing with the boominess. The boominess is caused by the sound boucning off of the structures walls. It all depends. Acoustics are a bitch, but the first few rows are where the room tends to be taken out of the equation, its just raw PA. power. I like using omnis up close because the are the most forgiving to head movement and tend not to have any proximinity effect(increase in bass ussually assoc. with cards). However, its when you are recording from the back that is when you want the cards, preferably on a stand. These take the room out of the equation by their directional pattern, hypers take even more of the room out and the reverse is true for sub cards which are between an omni and a card. pattern, they add room acoustics. The thing to remember is every room is different, as well as every Pa. is different, its always a crap shoot, but if you use the above info as a starting point you should come away with a good recording...........I hope all this info helps and just doesn't add to any confusion.................................JK
