I used the CP-4s, along with another set of Nak 300s with the CP-1 capsules, with the gain turned down on the CP-1s until there was no clipping on all but the loudest notes of the concert. I was using just the shotguns this summer when I started taping and wanted to see how the CP-1s sounded side by side, and the recording seems to sound the best with the sources blended together. The CP-1s pick up more talking but seem to complement the CP-4s and help to fill out the sound. I'm new at this, just learning as I go. Might see about adding some more mics, maybe not, we will see.
