this question will show my ignorance - i have no understanding of db:
Running 460>m148>pmd670
what db level am i at.
the M148 i believe is fixed at +10db, the 670 (-20 with the switch on) which would bring me to -10 db. does the level control on the 670 add 10 more db or just increments of db control.
then if i add the -10db switch on the 460's i would be recording at -20db again.
That is the first quesiton if at all coherent.???
the next, if this deduction is correct and i am recording at appx -10 or -20 db, where does the ACM performed by oade place my recording level? what does this mean from their web page.
" XLR mic inputs have an input overload point high enough to accommodate +4 dB (XLR/TRS type) line level sources with plenty of headroom to spare."
i am trying to figure out what sort of mod would be good for what i record (jazz,swing in small but amplified venues and bluegrass)??
as always,
thanks

Well the 148 is fixed +20 db gain and are you going line in or through the XLR's? I would highly recomend going line in for sure! All the other stuff I have no idea about :-\

plus 20, my bad.
i am running xlr in on the pmd.
i guess i dont understand what +20 means or +4 on the ACM660

if you run line in (ie. xlr from 148>rca to 670). you will get the 20db of gain from the 148 and bypass the pad on the 670. the dial acts as an attenuator.
