It's good to have a 45 degree angle, but I think you're getting a bit confused here. To avoid phase cancellation, especially if/when the result is mixed to mono (which you have to allow for in the profession because the product's going to go out on AM radio etc.) you want the mics *coincident* i.e. as close as possible, hence often crossed with one above the other. The 45 degree angle with a standard cardiod mics produces a forward facing cardiod pattern in the mono mix and gets the optimum stereo picture. Pointing further apart you get a hole in the middle and pointing closer you just make it narrower. But then there's ORTF where you put the mic heads apart and facing 120 degrees away from each other, which breaks all the above rules and yet some people swear by it for gettin a room ambient right. But not for drum kits, so I digress... -- Anahata anahata@xxxxxxxxxxxxxx -+- http://www.treewind.co.uk Home: 01638 720444 Mob: 07976 263827
