I have just put together my new head end rig and I have a question for BMax owners. I am running the BMax into a QSC RMX 1850HD. I notice a large increase in volume when I use the unbalanced 1/4" connections rather than the balanced XLRs(plus a little more noise.) for the same settings. The Bmax manual states the the two outputs are both controlled by the master volume pot and either can be used to drive an amp. Is there a level difference between the pre amp outputs or does the QSC have a preference? What is the preferred method of interconnection? BTW, I blown away by the sound either way!
