Topic: Running NOS close on the stacks? 4 mic mix...

I like the omni sound outdoors personally, but I do like to run the stand high with them due to crowd chatter.  As far as the cards go, maybe you should run x/y to help minimize the total bass response that you'll be capturing. You know, kind of compensate for the amount of bass that the 3' A-B omnis will likely be picking up.

i believe they are the line-arrays then...

FOH Speakers
JBL 4889 Vertec Full Range
JBL 4880 Vertec Subs
Meyer MSL-4 Self Powered Loudspeakers
Meyer MSL-2A Loudspeakers
Meyer UM-1c
XTA dp226 Loudspeaker Controllers


x/y sounds like a winner then.  i'm very excited!  it's my only show of the summer unfortunately, i've been too busy w/ work!
i'm thinking 10'-13' or so...

excellent point. I had completely neglected that issue...

hmmm  ya'll got me debating on setting the rolloff to the highest freq...  right now i have it on 195Hz but the next and highest setting is 888Hz.  (16Hz, 69Hz, 95Hz, 107Hz, 160Hz, 195Hz, 888Hz)

i could always use the mixpad to roll some bass off too i guess.

the one time i ran splits, i didn't notice any extra bottom.  the opposite if anything.  i was 25' at stage lip, so that would be a difference there.

i'm bad w/ names, but isn't x/y 90%, coincident? sounds like a good array to me w/ the splits.

FWIW - I'd run at about 69hz, maybe 95hz

you would be losing a lot of music by going all the way up to 888hz...

do you know how steep the curve is? probably either 6db an octave or 12db an octave

On the bass roll-off issue:  Make sure you do the conversion to determine what the actual bass roll-off is for your particular recorder.  The bass roll-off figures listed on battery boxes that aren't custom built to your specs are designed around a 'generic line-in impedance of 10KOhm'.  I use the pcm-m1, which has a 47KOhm line-in resistance. Search the threads on bass roll-off, and you will find correlation charts for the m1 and jb3 (I believe the jb3 line-in resistance is in the 37Kohm range, but the info is listed in the threads I speak of). For instance, in my stealth signature: My battery box has only 2 roll-off options, 150hz & 32hz. I don't really like to use roll-off, so I use the lowest setting available (32hz). This correlates to an actual roll-off of only 6.8hz (i.e. 32/4.7). Most people are rolling off much less bass than they believe they are because they don't know that the boxes are designed around this 'generic line-in impedance of 10KOhm' and that a correlation to your recorder is required to be accurate. Just something to think about. I verified this with SP and with the person who built my custom box. It's a typical design standard that they use.

do you know what kind of PA they run? If it's a line-array system then I wouldn't go too high... the mix will sound better closer to head height

and the screaming idiots will be much clearer at head height as well.

exactly what I was thinking.  Head height at dmb will do a great job capturing some 15 year old chick on her cell phone.  Then again, experimentation is fun.  At least you know there will likely be plenty of other tapers there so don't worry about coming away with a crappy tape.  Part of the fun of taping is trying different things, imo.  There's been more than a few times where I came away from a show thinking "damn, that's going to sound like shit" only to be pleasantly suprised on playback.

note that I didn't say to run AT head height, just that closer to head height will be better... the setup of the PA is just something to keep in mind, there are other factors to conisder
