I got sort of mixed results from my first try with these mics. Unfortunately, my seats were farther back from the PA than I'd hoped, and the volume from the PA was not as high as normal for a rock show. The audience was relatively quiet, however, but to my ears, the recording sounds a bit distant.
The first thing I noticed is that the treble seems a bit rolled off compared to my omnis. Is this normal for the CA-11's?
The second thing I noticed is that the mics seem very, very susceptible to being moved compared to my omnis. Is one supposed to remain perfectly still when taping with cards? I'm not talking about turning around 360 degrees, or jumping up and down, or anything extreme like that. I usually bring a camera to shows, so I was obviously moving my arms when I was taking a few pics with the zoom lens on my small camera. I was also a bit paranoid about how the mics were clipped to my shirt, so I probably fiddled with them a few times too many.
The cards were very good at rejecting noise from the yappers around me, and I suppose that's one of the main benefits of them.
