Hi Tom,
Great to see some home builds, and your blogs are excellent.
Have you compared EM172s running to a small miniplug recorder eg Sony
M10, against your setup with 172s wired for XLR 48 volt input to
Tascam? How much difference is there?
I would question the need for the isolator, if mics are on a fixed
tripod it should be OK? I've never had any problems, but I do make
sure nothing will be tapping against the tripod legs e.g. grass,
branches.
