Mike bar for Decca tree

Archived from groups: rec.audio.pro (More info?)

Does anyone make an adapter to connect 3 mikes in the form of a Decca
tree to a single mike stand? I imagine it would have to have some
means of balancing the load.

Thanks,

Norm

But the prices are some kind of joke, no?

Dig up a money can in the back yard. The mics you normally put on that tree
can run up some dollars from a safety standpoint.

I think it could be build using the Bogen triple mic t-bar as a start.
You would have to find some place that would sell you 25mm diameter
tubing to get the proper width you want. The rest of the parts could
probably be ordered from Bogen. It's sort of like playing with tinker
toys.

I'd have to search Bogen's expansive website to see if it could be
done. If it can, the stand would be solid as a rock, highly adjustable
and most likely under $200.

There is enough hardware here to put together a decca tree (not
including extra tubing):

http://www.micsupply.com/standaccessories.htm

Plus you will end up with a lot of parts that can be configured to do
just about any type of mic setup. All the tubing is aluminum. The mic
mounts are cast aluminum, machined where it needs to be. Good stuff.


It's not exactly low profile... but neither is a decca tree.

Manley has the original Starbird pattern and they are still making the stands.
They are just just as solid as ever, but you don't even want to know what they
cost these days.

The Atlas stands used to come a near second, but the current Atlas stuff is
just flimsy junk.

Ummmm.... this sort of defeats the whole principle, doesn't it?

In fact, if it's a real Crown PZM, the top end response of the capsule is
specifically rolled off to compensate for the high end rise when it's mounted
on the plate, so it will make a pretty poor small omni by itself anyway.

BUT, since a small omni won't work worth a damn in a Decca tree anyway, it
is sort of academic.

Most mic stands in general seem to be junk. There are a few exceptions. I
started using Avenger lighting stands and booms. Much better though a lot
heavier. Big mics stay in position.

The Decca Tree mic arrangement doesn't follow any particular rules but
just happens to work because of the pattern characteristics of the
Neumann M50 that makes three mics a few feet apart in a triangle a
"Decca Tree." Anything else is just three mics a few feet apart with
the associated phase problems. Nothing special.

You may be able to rig something with partially absorbent baffles to
approximiate the high frequency directivity of the M50. If it works
for you, name it the Norm Tree. (or something)

I actually was surprised at how well the 1" B&K measurement mikes work. With
a ball around them, they are beamy enough to be surprisingly effective. Have
you ever tried any of the Gefell stuff? I have heard some of their large
diaphragm omnis used in a Decca tree and it sounded very close to the classic
Decca sound.
