I've used a radio shack cheapy at band practice and I understand the theory of isolating the element from all reflections except the one source.But I'm thinking about geting a couple of Crown PZMs and setting them up for 48 volt phantom power and balanced XLR.Anybody have any experience with a more pro -type application of these puppys?General discussion welcomed.

I've Had a Little

But not much experience with Crown PZMs.

Good question! Anyone?
 
My drummer has one of the radio shack models,about,10" by 12" boundry plate electret condenser w/onboard battery about ten years old.We have used it on high wall placement and on ceilings for band practice taping and I have been amazed how it cancels normal room resonances and reflections.Also used it for drum overhead.
I'm looking for a relatively inexpensive way to get good room tone without the usual hassle of multiple eq passes to correct for the hash.
According to the crown literature,stereo room placement is recommended for 20 feet seperation minimum.The psycho-acoustic effect must be tremendously wide!In effect,our ears are pressure boundry receptors focused about 8" or so apart (I'm sure you are aware of binaural recording in the 60s and how cool that sounds,the aural equivalent of a GAF Viewmaster)so that advise is counter-intuitive.
I'm just a home hobbiest.What are the pro applications for this system?I'm talking about pro audio,not the business class conference market most of the mikes are aimed at.

They Work the same.
I use a PZM as an overhead for my drumkit, and I love the sound it gets.
The Pre-Amp is starting to go bad, so out of need, I'm going to convert it to Phantom power.

There's a guy on the net who has used them ever since RS carried them-and he used them alongside The Crowns, and said they were almost exactly the same mic-and that for some things the RS versions worked better. he was using them for sound at an outdoor venue for plays. I first read about this guy when I was a Compuserve user (The Net was still kind of "new" back then, and I was going through the companies that offered other services...
