Thanks for the comments. No battery box with the CAFs, levels were easy to dial in and it wasn't a loud show so the little bits that were recorded sounded pretty good. I think the CAFs, no battery box, acoustic electric show and close to the stage is perfect for this application. No headroom needed and no worry about brickwalling or high spl. I replaced the original 2g card right away when I got it so maybe it works using that one but I could not find the 2g one last night to try it out. I tried 4 different sandisk 8g class 4 cards last night and it gave the same error message before stoping abruptly. The message is so quickly gone if you not looking carefully you will miss it (2 secs on screen max). All 4 same cards work fine in sony m-10. I will try and find original 2g card and try that. BTW it also does it without an external mic and just using the onboards......maybe it just doesn't like the cards or 8g card is to large even though they say 4 and 8 work also. I kinda like the little guy and if I get it going I will also try CA-11s. Both should work fine in this unit for acoustic shows up close. The other night I could have had my feet on the stage lip from where I was sitting and with the little deck and CAFs shrinked to my glasses no one would have known I was tapping (or trying i should say). At the time I just keep restarting it since I missed the message each time. At set break I went over every menu item and all appeard to be fine but same thing happened second set.
