Stereo Bars and Blumlein Mic Accessories

[Ribbonmicguy]

Joseph,

AEA has great stereo microphone accessories. From Blumlein to stereo bar, to Decca tree, and everything you would ever need for stereo coincidental miking.

Josephson has Jecklin disc as well.

Cheers,

Grab the Shure A27m, mod it like above , and youll have a bar that is very versatile. I use it for every configuration. Also, the K+M 235. MBHO sells a J-disk, and add a decca tree to that and youll be set! AEA is great, but damn expensive. 300 for a mic bar is a little steep.

Absolutely, a total put-up.

For an example of adequate, I bought this bar for guess what, 8,00 Euros retail. It´s not too versatile, but the outer positions of the srews are exactly 17 cm apart, so that should be fine for Blumlein. It´s of massive aluminium and sturdy enough for that I used it as a tool to center and force a heavy stands rod into the uneven body thread of its base.
Oh, and it´s made in Germania, not even by teethless sweating morlocks in a melting arctic prison camp.

Comes to show what´s actually possibly aside from ripping people off yet over the roof top.
... Hey it could have been a bit higher labelled too like say 15 bucks and still be decently offered. Only not 50 or 80 or whatever you would have to roughly expect otherwise.

No, this is not a rant, it´s a celebration. > smacks a kiss on your forehead <

K+M 235

with those two bars and a jecklin disc
http://www.core-sound.com/jecklin/1.php you can do nearly everything!


I also have a custom bar for meter spacings.




My Friend made this for me. Note the modded shure a27..

if you have time to kill, the best option is buy 3 of the AEA sliders and go to home depot and buy a 1" x 1/4" steel bar, a 1/4" drill bit, and drill holes and draw measurement lines on the bar.

Took me six painstaking hours. I don't recommend it, unless you consider your time to be worth less than $30/hr. I only saved $180 on the meter-long boom.

[Jim vanBergen]

The Core Sound Jecklin disc looks nice, but at $239 how far off is that from AEA's pricing?

(I tend to do the K&M bar or painstakingly measured but WIDELY SPACED trees. But I WANT the RIGHT Decca tree tool, even though I'm quite pleased with WIDE placement.)

I just use the Bogen 3110 Triple Mic Support for my SDCs. It's flexible and fairly inexpensive and can be fitted to a mic stand or a light stand.

Also, I got creative with a light stand made for a DJ rig to make a low cost Decca Tree. It may be too bulky for some purposes tho.

Good stuff TeddyB!


Yeah...i use the Bogen as well

Goes nice and high and sturdy as...

[rufus13]

Teddy's idea for threaded extension tube on the A27m holds a pair of AT4050's in their shock mounts perfectly. The tube can be metal or PVC and is subject to any kind of mod's you like.

I've borrowed and used the AEA bars, and they look good/work great. The cost is is line with what they are (built for all eternity of hard daily use), but the same function can be had without the A+ cosmetics for far less.

The Sabra stuff is a good deal at that price-point, but it's not suitable for heavy LDC's or big microphones like RE-20. Too much plastic that smooshes flat instead of holding position. Sabra is recommended for pencil microphones or tiny microphones of little weight.

Cheers.

I may be stating the obvious, but here are two very cheap Blumlein setup ideas for those who don't want to spend a lot of money:

1. Get one of those $25.00 stereo bars that has articulated arms. Thread that onto the end of a boom, such that the stereo bar is vertical and the boom arm is horizontal. Attach your mic shock mounts to the stereo bar, facing each other. One will be right side up and the other will be upside down. Most LDC mics sitting in a normal shock mount will just about meet tip to tip. You can move the stereo bar arms closer together to close any undesired gap.

2. Get two of those little $13.00 clamp-on mic booms. Mount them both on a standard mic stand, the bottom one right side up and the top one upside down. Put a shock mounted mic on each, and adjust for height with the clamps that attach the mini booms to the stand.

Both of these rely on having solid weight on the mic stand base, but that's going to be necessary with two mics no matter what you rig up.

Cheap mics and not very fancy - but it works well!

[Remoteness]

That's cool rig.

Jecklins are pretty easy to build. I did the deed with an LP, sound deadening foam, fake lambswool and a mic clip. It worked for my OKM II's and now I need a four inch mic extension to make it work with some DPA's. And homebrew is fun.

I've used various Sabra-Som bits and pieces to put together a Blumlein array with reasonably big LDC mics, and it worked OK. I see your point though - it would be nice to have a little more metal and a little less plastic. It is an inexpensive way to have the capability to put together pretty much any configuration you can think of. I bought a couple of 4' lengths of aluminum hex rod so I can make longer configurations as well.

Mine's made of 1/4" plexiglass with a little batting and faux fur from the fabric shop.

It's quite the conversation piece and people always want to pet it!

Since I'm posting picts today , might as well.......

I've thought of getting those - I think a TapeOp-er posted that or something similar.

Bap,

Your setup looks great - I hope you don't mind if I give it a go!

Just a quick question . . . it's not an issue with the mics I intend to use (because of the way the shockmounts hold the mics), but where do you put the XLRs when you've got the ribbons mounted like that?

MohThoM

[bap]

I just trail them (the cables) along the boom and knobs and give them a quick hitch around the stereo bar - it's a wee bar but one of those bullet proof AKG ones.

Actually, I just thought of this mounting today but have been thinking off and on for a few days because I needed something this coming week and didn't want to spend a lot. I'm amazed that something so simple was there all along!

(The bottom mic XLR dealy has been moved to the other side - the photo shows a stupid re assembly on my part)

[NoPro]

I have flange mounts on ceiling on a piece of wood. I then connect a few long goosenecks... Then a regular mic stand for mic on floor to meet the other mic... Well that's my 2cents. Actually 30 ,40 bucks or so

[take2]

I've recently needed a mount for coincident mics, so thanks for the previous replies.

I went for a clamp-on mic stand boom attachment (about £9 from various suppliers in the UK) which gives a variety of options attached to a straight mic stand or a boom stand.

Without the advice in this thread I'd have been spending a fortune on some Blumlein bar or other mount for mid-side mics.

Thanks!

Rich,

Are you planning to extend the bars? 1m20x0.65 is a bit on the smallish side, or innit?

[richgilb]

It's only 30cm short innit? A mini tree!

[Bibster]

plus that you could easily pop-out the plastic thinggies in the end of the tubes, and make some extensions! use some M10 bolts though the existing holes to hold it in place...
The little helper triangle on the 2 smaller bars (Your forward boom) is neat!

Maxi-tree? ;-)
