Topic: Matrix Delay

[china_rider]

Hey all.... I pulled some matrix recordings this weekend from a small local fest here in Phoenix.  It was mostly local bands and then New Monsoon and Delta Nove.  Anyway, I had never patched into the board in this venue but from the past matrix recordings I did I was expecting about a .5 second delay between the mics and the board since I was about 40' back.  However, the SBD tracks are actually about 6.5 seconds off of the mics.  I had never seen this before and was wondering how common it was.

Thanks,
Dana

i've had some hectic delay before, but 6.5secs is unheard of. i recorded at a world music fest this weekend off the desk and the delay with my headphones on was obvious with the music is the background, but probably about o.5sec. not sure man!

was it a digital desk? if so, it's entirely possible that the send that you were recieving was from a send that was set for a delay stack. i know on the M7 and the 5D a couple of the omni/matrix outs have a delay set on the output for just this reason. 6.5 seconds seems drastic, but perhaps the default was changed accidently and nobody noticed it (except you and your recording).

Sounds like the infamous 7 second broadcast delay... in case anyone on stage started swearing or saying anything bad about Bush!

Or not.

Weird.  At one of the Wakarusa sets this year, I had a similar but opposite occurence with the R-4 Pro.  In that case, the difference between the SBD and AUD tracks was only ~ 5ms although my mics were at the SBD which was 40-50' from the stage. 

At least we're post mixing tracks with the R-4/R-4 Pro units and the delay issue does not matter.

why wouldn't the delay matter? wouldn't that be the only concern since the tracks are on the same clock and won't drift once they are aligned?

The relative delay between AUD and SBD tracks only matters when mixing on the fly.  When mixing in post, since they're on the same clock and do not drift, all you need to do is align them on the time ruler of your DAW before mixing.  You would have to do that anyway whether the delay between the AUD and SBD tracks is the expected ~ 1ms/1' distance from sound source or some anomolous difference like the weird case we're discussing.

gothca, the delay is a problem but easily corrected in post, i thought for some reason you were saying the delay wouldn't be an issue because of some factor of the R-4

Well, yes, but only because the R-4 captures the tracks as 2x stereo or 4x mono, and then you must post mix.
