Title: Quadraphonic Tweeter Show
Post by: Gedit on November 19, 2006, 09:30:43 AM
The Disco Biscuits have announced that their New Years Eve show at the Tweeter Center (Camden, NJ) will be produced in quadraphonic sound. I've attended four-channel concerts in the past (e.g. June 1977 Emerson Lake and Palmer at the Spectrum, Philadelphia - four speaker towers at the corners of the General Admission floor space) and am trying to determine the best way to approach taping this show.

If you aren't familiar with quad see http://en.wikipedia.org/wiki/Quadraphonic for a description.

I'm running a Roland R-4, which takes four XLR inputs.

Any suggestions on mic selection (not brand, but type) and placement?

Any suggestions for post-production .. will the source have to be run through a Dolby conversion to play correctly on a stereo rig? Should I seed two versions, like 24/96 sources are seeded at 16/44 as wel?

just thinking out loud... if you wanted to just do a two channel thing you could try healy method omnis.

edit: now that I think about it omnis inside the tweeter center may not sound that great. shitty sounding venue + omnis = crappy tape

Ideally, a double M/S set up.

double MS would be ideal. or split omnis for rears and ORTF for fronts....or another config in front.

Please seed a 5.1 DVD-A (just don't do a center channel) of this, 24/96. Please, pretty please.

How about two pairs of split omnis?

4 cardioid mics: 2 stereo pairs angled at ~ 90°, one pair facing front, the other pair facing backwards.


I don't get the reasoning for using omnis here, you want to reject the rear sound from your front facing mics, not pick it up. Likewise for your rear facing mics.

in all seriousness, all it really takes is for one person to turn his rig backwards on the stand. you'll have 2 sources, mix a quad mix, seed please. you rock Gedit. :)

I guess I am misunderstanding your confusion.  Did you think that I would have suggested leaving them in a single plane?  Would there be something wrong with putting a split pair up and another split back?  In my experience I think that this would be a cool time to experiment.

Although for a show as loud as the Biscuits...I'd just stay home...

This is probably the mic arrangement I'm going to use ...

this is probably what i would do only go with hypers, if i had the resources. i'm don't see the need for a fifth mic, but then again i've never tried anything like this. good luck to you and jonathan  :)
lookin' forward to hearing the results.

If I was at that one and had a 744 to borrow I'd probably do double Blumlin (4 crossed figure 8s) ...but that's just cause I'm a wise ass  >:D

Seriously, I'm not even a DB fan but I can't wait to hear your pull of this show. I think Bisco will probably make better use of quadraphonic sound than the Dead would have (post 74 anyway). Should be interesting!

My friend has pulled a few of these (no quad pa system involved) - one pair of Neumann TLM103s (x/y for mono-compatibility for the l,r,c - facing forward) and KM184s (ortf) facing backward. He used Vegas to create a 5.1 mix and even though the mics were not consistent the results were good enough to warrant future experimentation....

And anybody who has ever used one of those will tell you, while they are awesome mics, placement is super critical with the Soundfield. You don't get them in just the right place and you're recording won't be what you were hoping for. I considered one, since Zaxcom has the decoding option for it in the Deva, but ultimately decided that it wasn't worth the hassle (or the price).

FYI, the 16/44 source has been released (http://www.archive.org/details/db2006-12-31.51surround.flac16) but it was suggested that I release the 24/48 as well so that people can burn a DVD-A from it.

That's in the works.

I can't wait to hear the 24/48 pull of this!
