What i want to do is spliting the signal from the concert scene. 1 to the FOH mixer and 1 to my stack of MOTU 8Pre's. I have had little luck finding active/passive mic splitters, but i found this one. http://tinyurl.com/2bksh9 / link removed er-180221-i1386012.Mu...FED-D C11-AA92-001422107090&mr:referralID=NA What can i expect from this product?
