Yes James, there is a lot of difference in their input levels. The
internal mic registers well at 50% input volume, and records
normally. The external mic doesn't register with normal voice, but
will register a loud voice. I can record with the external mic via
the line in, but the level is almost inaudible, even with input
volume right up to 100% in sound prefs.
With Garage Band the external mic gets much better sound levels for
voice - at 100% input level, a voice track is usable (although not
loud).
If I switch to the Audio In app and record (with input level at
100%), voice is barely audible. Definitely there, but barely audible.

Hi Glenn,
Like most other people, my first suspicious would have been "Line In"
versus "Microphone In" (i.e., pre-amp issue), but you wrote that the
input level is showing 60-70% already. Here is a little app that you
might use to compare your Internal and external microphones:

Is there any visual difference in their input?
