Scott--
Assuming L=3DMid and R=3DSide:
1) A mkh30 does have slightly more noise than a mkh 40, but not this
much usually.
There are three factors to account for: (a) the two mics, (b) the
rolls (c) the recorder/settings. Do things like swap around the
inputs on the Rolls. Power the Rolls and mics differently if you can.
Try the Rolls with other mics if you can. Make sure all the
settings/inputs are right on the recorder.
2) There is unusual low-end weighting/extra low end emphasis on the EM-32's=
.
Its early, but your tests so far suggest to me that something is not
right with the recorder or a setting/setting on it. Swap your
gear/settings and connections around and see if you can isolate the
source of the problem. Rob D.
