Lately I have had good results with mics above the main part of the orchestra, resembling
a Decca tree. In some acoustics this can remove some excessive reverb. Currently I simply
run omnis up there, guess next step is to make some kind of acoustic balls or similar.
Additionally I usually have outriggers and sometimes a spot here and here.
place a high stand right in front of the conductor (not all agree to that) and on top i
have this home-made T construction with mics at the ends. A picture may helphttp://trombonisten.se/images/4051c.jpg
The T is made from
three parts of aluminium U profile I found in a hardware store, bolted together.
