Hello:
OK show taped, MD level I set that halfway, ST-9100, since there was no red light clipping indicator so, I turned it up more and more until I reached the highest peak, still no clip, so leaved that way..... tucked all the gear inside my jacket, started my Casio G-Shock Chrono for the later infamous MD swap and enjoyed the show.
First hour of the show the sound was bad! and low it was heard like when you had a tight cassette tape, even the crowd on the back were yelling that they could not hear! I was on the first section side, huge venue, baseball stadium. lately the soundcrew made his job and fixed gradually.
So, basically the result a great recording even with the soundflaws, MD levels could have been higher but OK, thanks for the great advise
