Title: Omni configs
Post by: creekfreak on April 02, 2004, 09:47:08 AM
What are some other ways to run omni's besides split? Are there other configs you can use that don't require you to spread them mant feet apart? ORTF? NOS?

with omnis the best way, imho, is to split them.  when you are pushing them in a direction you really dont get the direction because they are, well, omni directional :-)

that's what I was thinking, with a pick up pattern like that angle, etc really means nothing. On to the next subject, what is a good bar to use to run split omni's, don't have time for the home made stuff...what works that is out there to buy?

There was a discussion about this a few weeks ago (too lazy to find the thread) but here's the low-down....

Healy method. Two omnidirectional microphones placed 180* w/ capsules at about ear distance apart.

0=  =0

  //  \\


NO! That's not a stick man! It's a damn pair of microphones :D  omnidirectional ones at that (look at the 0's)

Good luck

so those are pointed out?

Yes.  they form a straight line.

The only problem with this is if you're running pencil mics you've got to have them at least the length of the mics apart, but since i think we're talking abuot creekfreek's new TL's, i don't think it's really an issue...

so that is roughly 17cm, just like an ORTF (ortif) with the caps pointed out, interesting. The omnis I have done have been about 5 feet apart kinda *pointed* towards the stage

That's just regular spaced omni's is it not?

Found this bit in my bookmarks from the oade site

yes it is, I look to try the "critically spaced omnis" though
Title: Re:Omni configs
Post by: teajay on April 02, 2004, 11:19:40 AM
haha, or listen to Moke, if i remember correctly, that's how the last (and maybe other) omni placement discussions ended... :P

I'm yet to try it, but Moke isn't the only one i've heard swear by it...
Title: Re:Omni configs
Post by: twoodruff on April 02, 2004, 11:21:51 AM
critically palced omni's are for single diaphragm omnis, not intended for dual d. LD's.
J-Disc it! amazing results!!

that requires actual work on my part. Do you have the pictures of blumlein you used to have moke?

nice pics mike... i'm far too lazy lately to go through that work... what have been the responses from those around you from not only flying big-ass mics, but a giant block of wood between them?
Title: Re:Omni configs
Post by: twoodruff on April 02, 2004, 11:39:53 AM
For Blumlein, I think that Brian Costigans Shure Bar mod is the way to go. It's much lighter than the rig I've been using.
I've been combining a Shure Bar, and a 4 mic t-bar.

fetching.....

is this somewhere? I think I may have missed it

Just curious how well people (Moke?) think it would work to use sub-cards with a J-disk.  Many think that Red Rocks is not served well with omnis, but that sub-cards work well.  I'm wondering what would happen if you tried a J-disk set of sub-cards on the Rocks.

one way to find out........

Post by: C.Clark on April 02, 2004, 04:57:16 PM
when i buy the omni caps for my AT's this summer, i think im gonna invest a j-disk, it just seems to good not to use and from listening to you comments on it the past 6 months mike, i think the seperation and sound quality coming from that thing is gonna be off the hook
Title: Re:Omni configs
Post by: Tim on April 02, 2004, 05:05:48 PM
I've been lazy with the j-disk because it just seems like more shit to carry.

I'm still a bit confused as to why this is true. why does the fact that the LD's utilize two diaphragms to achieve the omni pattern matter?

okay, thanks for the picture. so do SD omni caps not pickup a true 360* soundfield because of the housing of the cap and the body?

that's what it looks like...

Not Moke's, but check out a couple pics down of Blumlein.  It's with the Fig8s though:

yes, j-disc in close parking gigs! I'm not carrying that thing all over red rocks... but the local jazz club I will.

Perhaps best described as an imperfect orb, or an orb with a slight, slight dent. Almost perfect with a blemish.

sound confusing enough? ;D

i get the idea, thanks mike, 12 hour thing

Yes, yes amd yes. I really only like to run BLumlein when on-stage. I think you can pick up too much unwanted sound when running in the crowd. Blumlein is like XY with LD's, with the mics set to the figure 8 pattern...

In my personal experiences, when Blumlein is run on-stage, you pick up the perfect amount of audience noise and chatter. The low crowd rumble between songs, with the occasional whoot and cheer. It blends perfectly with the music though when on-stage. I guess this can really differ depending on the venue and stage setup, as I know some stages in some places are merely raised by only a foot. The venue where I run on-stage has the stage at the pefect height, and the acoustics on the stage are simply awesome. The best stage tapes I've ever made come out of this venue, with the stage at about 4 1/2' high, and the crowd kept away from the stage with a barrier by about 2' to 3'.

Don't forget blumlien outdoors with open skies and flat ground...  perfect scenario

I may try blumlein at Odyssey fest in 2 weeks, although its shaping up to be a four word answer:

To me the only perfect scenario is on-stage. There is still too much unwanted sound behind the mics to be picked up when in the middle of a crowd.
