I also realized that DR-2d has a much quieter recording result than my Edirol R-09HR. But I did not set it to MID gain, because I recorded from Sbd too and it would be too much in that case.
Oh, one QUESTION:
I was at an acoustic show (what is very rare - turned out very cool) and it was quite quiet, I used CA-9200 preamp to add +20-30 gain. (Didnt want to stop and set DR-2d during the show) Would you do it, or either set DR-2d to MID sensitivity? Any difference, advantage, disadvantage?
MLKLuke:
I think the most important to check if you use line in, shouldn't peak. In that case you dont need a preamp to change leve input. But it could be really quieter than using mic in, so the CA preamp with plus gain can be useful.
Also check mic in. If with 67 level does not peak, you're good.
I have only one preamp by now, so I try to test at the soundcheck if which one (mic or ine in) does need to lower than 67/97 or need much higher than with 100 set at Tascam.
I must say, I couldn't really make similar vol levels with both channels, so I edited them post for mixing 2 channels.
