Re: TVI Audio C210ii Line Array
Try this. Use your RTA and set the graphic flat (as in a straight line on the graphic-NOT a flat response on the RTA.
Adjust the gain so the majority of the response is towards the upper end of the RTA (up high so to speak).
Now grab a freq on the graphic-somewhere towards the middle of an area where the response is kinda flat. Pull it all the way down. Notice that more than jsut the freq on the RTA associated with that band will also be affected. Now turn down an adjacent band and notice the RTA response.
You will see that the band have a bit of overlap and affect each other.
Of course with an RTA you cannot see what is happening between the bands-but it IS being affected. As with all other audio filters-they do not stop where the numbers are-but rather the numbers are simply a point on a curve. There is lots of interaction and overlaps going on-so things are not as they appear.
I admit I was unaware that the frequencies on an equalizer affected each other.......I've seen several sound guys just pull out the frequencies that aren't needed.....I'll try it flat next time :/
