I thought someone suggested setting the MT levels to 4dB and then adjusting the gain on the pre? I'm not positive about this but I thought the advice was to adjust at the pre when using a pre? At least that's what's been working for me. Of course I've been running my open taping rig with those settings on the MT. But all my gain levels have been adjusted with the pre. I plan on running the Church-Audio ST-11 cards>9100 pre>1/4" TRS inputs>MT in November, if nothing sooner. Maybe I should check mine out and see that it's working correctly.
Your sample sounds a lot like mine have sounded using omni caps. That's why I bought the CA ST-11 mics with additional caps for that reason. Indoor venues aren't that good for omni caps unless you are REALLY close to the sound source. I'm assuming you taped in a large arena? I've been "fixing" some old recordings with software so they are still worth keeping. All I can say is keep trying, you can't have success without failure. Is the Black Crowes outside or inside venue? Outside your omni's would be great, but inside....I dunno..
