Want to try XY setup.
« on: April 02, 2003, 02:14:01 AM »
Got a question and I hope I ask it right.  I want to experiment with something new tomorrow night at Guster.  Normally I run my mics about 24” apart and facing the same direction, straight ahead.  I want to try and do a 90 degree XY setup and see how it sounds.  Not sure exactly the right way to position them.  Have two ideas in mind.  If you are looking straight down on my mics: the mic on the left is angled 45 degrees to the right and the right mic is angled 45 degrees to the left.  Or should it be that the left mic is angled to the left and vice versa for the right.  Or should I even be trying something like that with cardiods.  Maybe I will just run like that for the opener and then  back to normal for Guster.

go to microphone university, stereo techniques and click on XY...picture should help you determine how to set it up correctly.

The Oade page also has great pictures of all kinds of different configurations. Look there too...... that's where I learned.  ;)

Normally I run my mics about 24” apart and facing the same direction, straight ahead.  

If you run that way I think you'll basically get a mono recording because you're getting the same signal in both channels, minus some cancellation. The only time you want your mics spaced that far (or farther) is if you're running omnis. For your cards, I'd say the XY will definitely give better results. Maybe try XY for the opener and something else for Guster? DIN, ORTF, etc...experimenting is fun! ;D

I want to try and do a 90 degree XY setup and see how it sounds.  Not sure exactly the right way to position them.  Have two ideas in mind.  If you are looking straight down on my mics: the mic on the left is angled 45 degrees to the right and the right mic is angled 45 degrees to the left.  Or should it be that the left mic is angled to the left and vice versa for the right.

Basically, you want your left channel mic facing the left-hand speaker stack, so if you're running XY, the mic will be on the right-hand side, facing left. And vice versa for the right channel mic.

That said, Guster's new sound guy, Gordon, was really helpful to me last week and it looks like he wants tapers to get good tapes (as opposed to their last sound guy, who was a nice guy but could barely form a coherent sentence  ;) ). He'll probably help out if he's not too busy...

Wouldn't mind getting a copy of your pull if it comes out, Kevin - got plenty of Guster to trade including 4 or 5 shows at the end of the tour...

Cool guys.  Thanks for the help.  I believe there are actually 2 opening bands so more experimenting I guess!

Not true.  This is the "A-B" technique and will yeild a stereo image due to the timing differences caused by the spacing.  Sound originating from some point in space will arrive at the two mics at different times, when played back on a stereo system, your brain will use the timing difference to create a localization of the sound.  A-B can suffer from phase cancellation problems, though, and may not give you the best results.  You should try some of the other stereo micing techniques (x/y, ortf, nos, din) to see if they sound any better than the 24" spacing.

More great info on A-B and other stereo techniques at the DPA "Microphone Univ."

Thanks again for the help.  I think I am going to try 90 deg X-Y and NOS.

Aha, cool...I didn't know it worked/was used with the more directional mics. I've only ever heard people talk about spaced omnis, never spaced cards/hypers/shotguns because I would think it creates a "hole" in the middle of the soundstage.

For lack of a better setup, I was actually running spaced cards too when I taped...talk about a jury-rigged configuration - I got the Sabra-Som T-bar before I read any reviews of it, in anticipation of eventually getting shock mounts (and mics that would fit them). ;D So I used the thread adapters to clamp a 12" ruler across the T-bar and then clipped my AT853's to the end of them. Better than nothing, but worse than plenty...

Got my new toys now (Elation KM201's FINALLY got in the other day) so they'll get the trial by fire at Bela next week! w00t!

A few of those say you need to be careful and pay attention to which way your diaphram is oriented.  How do you do this?

This illustration should help.

 ;D

That is definately helpful information but not sure exactly how to apply it to this situation.

Between that diaphragm orientation and the practice of waterproofing microphones with condoms, I'd say your gear would be well-protected against any STDs. ;)
