[QUOTE="John Neil, post: 2988, member: 422"] Tonight, 800 cap club, historic theater. Sold out show. Me, house tech. System alignment done by me. Needs some refinement but is a good middle ground for the shows we do. Real PA. Watts, boxes, processing, two balconies, zones, delays, etc. Band carrying everything, me just racks and stacks today. Venue desk and snake stay out for support. I'll do five mixes from FOH so that the venue mon desk can be struck and save space on stage. BE hands me left, right, subs and front fills. We have inputs duplicated in processing so getting between the two desks is a snap. Done. Band is a B national with an upcoming Letterman slot. Typically they tour with a pretty serious A national arena show, so they are used to this game where appropriate PA is deployed and ready for them. This is a BE that regularly rubs shoulders with system guys from the big C touring provider. No sooner than I have turned the rig on, I'm asked about the crossover of the system between L/R and subs. I reply with some reflection regarding electrical and acoustical reality of the setup. Next I notice, BE is using output graphics on the Profle desk as "death above" and "death below" filters for his four outputs to me. BE goes on to EQ the rig using inserted parametric on L/R, nothing on subs, nothing on front fills. No time alignment, no listening, all via pretty traces on SMAART. Long story, but the phase shift at crossover imparted by the death above/below application was never accounted for. Non-trivial in this application given my insight into the crossover slopes and traces I used to get things where they are. Does it matter, yes, but no. Show was fine. I'm trying to reconcile my knee-jerk negative reaction to a band guy messing with my system, especially without listening first. Yes I'm personally attached. I'd say 15% of band guys in this role seem to want to crossover via EQ in some form. He had a fine show, really. Had he listened to the system (or measured) and had a request, I was standing by to make requested processing changes via laptop. What I seek is some insight into the EQ as crossover mentality, especially death by convention. At this point I figure I must be missing something...something that happens in the big leagues with bands you've heard of. Anybody. "Stop caring" is also a valid suggestion. I recognize my inability to get over it is a part of the issue. Please, help me appreciate the rationale. [/QUOTE]
