Line array question.

(1/1)

Al Rettich:
Has anyone ever seen this before.  Yesterday I went to visit some old friends on a tour. They had the new Panther rig out.  It was explained to me, that each box had its own channel of control through (I think it was calisto) controller.  What got me, was for 90 mins the SE took a measurement mix cabinet to cabinet checking delay. Soundcheck sounded good, and as Iíve learned if it sounds good doesnít mean itís always right.  When I was touring CH always said treat it as one source.  Has this changed? If he was putting delay at each box where was his starting point? Wouldnít this affect the science of a line array? Iíd like to learn more.  Please tell me

Hard to say, but if he was running Galaxy for processing he could be verifying the low mid beam control feature.
It's basically an all-pass filter deployed to adjust the low end vertical dispersion.

Al Rettich:
I did see him writing down the delta delay from Smaart then going back into the control software for Meyer.

If he was delaying each cabinet differently, then it would only be good for ONE seat in the house (OK one area HAHA), everywhere else would really be messed up.  Tons of combfiltering, that is worse than the combfiltering you get with all of the boxes in a line array having the signal arrive to them at the same time.

There is no way to get most of the seats to all have the same arrival time with a line array.
