Hey guys, I'm new here (and new with sound) so please bear with me! Our church is portable and so we had no problems until a couple weeks ago... It has typically just been a cajon, piano, and my acoustic, plus two vocals mic'ed, but we had another guy who wanted to play acoustic. We have an X32 Compact that we run through the S16 by our stage via the AES50 A. We had previously used our acoustic channel once and it worked fine, but this time it was not working. We tried all the normal things you check like changing the battery, changing the quarter inch cable, even changing the XLR cables out, changing the direct box, and changing it all to a different channel... but no luck. So, then we took my working acoustic and its line and plugged it into the other guitars channel and even it didn't work. This was such a bummer and since both myself and our sound guy are new to the sound game, we have no idea what to do or try. Do you all have any suggestions for what could be causing this problem, especially since it has worked once before with the same exact setup? Thank you!
