My stealth rig is the CA-14c > CA 9200 > Edirol R-09HR. The numbering on the record levels are different on the R-09 and the R-09HR, so I will leave it to you to figure out the conversion. I get great results running the R-09HR around 40 with the gain on the 9200 at +30. The volume on the 9200 is hovering around the half way point to a little past half way (I would estimate it at about a 6). This is for a concert in a major venue. I hope I've helped.
As for using the CA equip. with the Sony PCM-M10, I generally have the CA stuff at the same numbers and the M10 at around 4ish...in a bar/small club atmosphere.
