Hi Vicki!
I've been doing a little bit of experimenting, and a couple of points
have come up. Firstly, what I've discovered is that I get a higher level
reading with the Low cut off (makes sense I suppose, but due to wind
considerations I'd always had it on). Next thing was a question; do you
have the Limiter on? I had, until I noticed that recovery times were not
as good as I thought i.e. after a sudden peak it took a second or two to
recover to previous recording level, which leaves odd sort of holes in
the recording. I am going to start using it without I think.
One of the problems in this country (UK) is that it isn't often you can
get a day WITHOUT wind!! This is why I've just bought one of those
Indian blimps to house the ME66/K6 combo (which has just arrived).
I have found that this combo is much more sensitive, and as expected,
allows me to use recording levels in the mid-range. Whether or not I'll
be able to achieve level 2, as you did with your 67 is too early to
tell. I will report later on my use of this combo with the Indian blimp.
I am extremely impressed with your wind cover! All I have to do now is
discover a source for flyscreen gauze. It does appear that you're a dab
hand with a needle!
I'm awaiting a couple of other purchases at the moment, these being an
Art Phantom II, and a pair of AT3032's. This will give me a huge amount
to experiment with over the coming winter, and hopefully by next Spring
I'll be ready for everything happening!
One intermediate project I have in mind, involves the huge numbers of
migrating birds that pass through the north coast of Norfolk in Autumn,
not too far from my home.
But I digress; very many thanks for your input to date, and in the future
Regards
Max
