[QUOTE="Spenser Hamilton, post: 99584, member: 2272"] Re: BEs and System DSP Most recent measurement was done with a DBX RTA-M into Tascam US-200 into SMAART on my MBP, mic on a stand at FOH position. Didn't save the measurement's which I am kicking myself for because I would love to have some of you guys rip them apart. I just received a Rational RTA-420 with calibration file so perhaps I'll make a point of do so next time the rig is out. As far as what I was able to measure: The subs were hay stacked due to the fact that we were running three 728 per side, I pulled back the sub pass band about 2dB prior to the artist arriving only to have the BE request that I boost the subs during soundcheck. There were a few spots in the 200-800Hz and also the 2-3KHz range that needed to be tamed on the FOH graph, and as I stated previously there is the rapid drop in response in the very high frequency range. Phase between the sub and mid bands looked good on screen, the phase at the upper end looked not so great - probably due to the fact that the ceiling was about 4" from the top of the stacks! I'll gladly start a new thread when I get a chance and post some measurements, I always appreciate when you comment Art, even if your comments usually consist of schooling me on how to improve in this business.
