Hi Guys,
I'm doing the best I can to help solve these problems without a BMC on hand so forgive me if I make some mistakes or get a touch annoying with my comments and probing
just trying to help.
On professional audio equipment line level inputs & outputs are preset to 0dbu or +4dbu (the later being more common)
If the output is sending +4dbu and the input is expecting +4dbu then things should be right at 100. Though there's some wriggle room on the BMC to bring the input down. But in reality the output can't send more than the input is expecting.
unless... the mixer is sending too hot a signal.
I've done some research and may have found the mystery.
The Riggy micro only outputs mic level, not line level.
Frank, I think the Wendt has line level output. (there should be some switches under the XLR outs MIC/LINE)
Michael, The only way around the mic overload safety, if it needs to stay in the BMC, is to get a field mixer with clip limiting. ie sound devices of the top of my head and probably some others. In a controlled environment, setting the levels a touch lower can avoid this too. But where's there's the possibility of loud peaks, a clip limiter is the way.
I hope you all are having a great day!
Paul
