Topic: TL users.. Is horizontal XY ok?

[Brian]

here's a great post by JP Gerard from the adkmic forum about configs with the TLs.

"The basic configs are AB, XY, MS, ORTF, NOS, OSS etc.

You can find them with diagrams and full expalation on the net but in broad strokes:

AB: typical spaced pair, there are no real guidelines... but the 3:1 rule is worth keeping in mind.

XY/Blumlein: coincident pair, 90° is a good start, placing the capsules on top of each other is a good idea for optimum phase coherence, I usually end up around 80° but some folks use up to 120° for a wide image when taping large formations. Use Fig-8s for Blumlein, 90° angle.

MS (Mr. Blumlein too!): a fig-8 and a (typically) directionnal mic going through a matrix that basically flips the phase of one of the fig-8 mic signal after multing and mixes it with the cardioid.The balance between the mics will determine the center "depth" or stereo "spread". Select the directivity of the M mic depending on how much "room" you need in the stereo image.

ORTF: variation on XY, 110° angle, "near coincident" since the capsules are typically 17cm apart.

NOS: like ORTF config but 90° angle, 30 cm apart.

OSS/Jecklin disc: a baffle around 1' between two omnis, approaching binaural performance."

I thought in MS both mics where set to Fig 8.

mid - cardioid

side - figure of eight.

if both mics were fig of 8 the pattern would look like this " + " instead of this " X " thus not allowing for optimal stereo separation.

This isn't an issue with symphonies or micing many instruments or vocals.

That part confuses me.

i have set the TLs up horizonal and vertical XY and had good results, though I prefer the vertical, as it is more consistant (i fucked up one show with horizontal placement; it still is OK, but could have been better).

I think Junkbondking said this a while back: the TLs are very forgiving mics.

I have ran my TL's horizontal many times, but have yet to run them vertical.  Most of my shows i think sound pretty good but after reading some of the posts on here i will have to run them vertical and see what happens.  So far i think my best show has been running split omni's

[keepongoin]

without a doubt, split omni and j-disk baffled omni are the best way to go, provided you are in a place where no one will be talking near your mics.  Blumlein is also an option that seems to increase the "depth" of the recording.

i think i'm running split omni's tonight on stage at jacob fred

First off, I have to say- I LOVE THESE MIC'S!  These are, without as doubt, the best sounding LD's I've ever heard (ok, a U-47 might edge these puppies out, but...)

I run 'em horizontal X-Y using a SHure A27M bar on top of a Manfrotto stand.  Sounds great, either in Cardoid or Hyper-C.  I am curious to try them in the Blumlein arrangement.  I have heard that this gives a broader "depth of field" to the sound.

I don't hear any phase isseus with them set up horizontally, and in this arrangement I can actually keep the diaphragms closer to each other than in the vertical setup (when you consider the space taken up by the windscreens and shockmounts)

Anyway- just thought I'd squeeze my $.02 in

wrong TL's... we're talking about the ADK A51TL's, not the AKG's.  but hey, those AKG's are pretty decent, too.

My bad- not familiar with these.  Enlighten me won't you all...

it's quite a popular LD mic these days especially for live concert taping. mostly because they are such a great sounding mic for sucha  great price and are very versatile   tons of us here run them.  I own a matched pair and have been really enjoying the tapes i've made! 

adk is a great microphone company and i really hope they succeed further than they have and continue to come out with great and affordable products.

Robert Kwon has posted on this topic a few times. I don't run my ld's horizontally...
