Mansfield ISD PAC 030115

Another year has come and gone as I do another Texas Ballet Theater “Peter and the Wolf” performance at Mansfield ISD’s PAC.

Same JBL Vertec PA. The house audio engineers Bret & Daniel were a pleasure to work with again.

For a refresher, here is the first post I wrote about the venue.

One of the things I have learned about measuring Line Array’s is that there is nothing magical about them. The overlap between each speaker in an array is ugly just like an array of speakers turned in the horizontal direction (like everything was done prior the rediscovery of line arrays in the 1990s).

So you have to choose where you place your measurement mic on a line array. If you walk forward and backward it’s fairly easy to hear where the HF (high frequencies) affect each other. I chose to put my mic on axis of one of the line array cabinets. The general rule is to make EQ decisions where it does the most good for the most people. I’m assuming that there are more people on axis of each line array speaker than in between them…

If you place your mic off axis of two speakers in an array you get a very different measurement than you do if you place the mic on axis of only one speaker. Next time I show this but I didn’t think to capture a trace with the mic in different positions (on / off) axis.
