Hi John,

Yes I have also followed this thread with interest, it's a subject I have 
thought about
for a while and recently made up a new array to address these issues and 
hopefully produce
recordings that are both mono AND stereo.

My main recordings have been in stereo with a parabolic dish, but stereo (using 
a pair of
Neumann KM183 omnis) can produce odd effects. I personally don't like the sound 
of mono,
but mono in a dish gets the best technical quality. So what I have done is use 
a mono omni
in a dish, a Sennheiser MKH20 and an XY Pair of Neumann KM184s used as open 
mics mounted
below the dish. That way where ever the dish is pointed the XY mics are also 
pointed in
the same direction so all recordings on the three channels are coincident. One 
4 pair mic
cable, makes it easy to wire up

Using a SD744T I then record on three tracks and post editing I can mix in as 
much of the
stereo as I want to 'place' the subject recorded in mono in the scene, or keep 
it as mono
it that suits the subject better.

Yes it is more bulky and not something I would go back packing with, but I am 
sure it will
have many uses. Apart from physically testing it in the garden (city area) I 
don't have
anything I can post as an example yet. Has anyone else recorded in such a 
manner?

See the photos I have just posted in the photo album section [3mic-array1.jpg &
3mic-array2.jpg]. Note one image also shows a motorised head on the tripod so 
that I can
remotely change the direction of the mics.

The aluminium metalwork for the mic support in the dish is adjustable, so I can 
fit any
mic or mic arrays in there to experiment with.

The dish and the XY array are bolted together, so they will more often than 
not, be used
separately. The XY array being very light and portable. In fact, my original 
aim was for
them to be used separately, but when I started to make them, I realised that, I 
could both
them together, time will tell if this works!

Mike
