Hi guys, I just got this AH350X for Christmas and don’t know a thing about it. I had an AH200 which I bought new 30 years ago but recently burnt in a fire. My question is about connecting to the Trace Elliot 4-10 cabinet. I know I should use the channel B XLR output but on the cabinet end, should I use the XLR jack or 1/4” jack? Also, the “Graphic Equalization” button is missing but the led “IN” is illuminated so I guess the EQ is enabled. Am I correct? And lastly, the button below that, “Middle Cut Pre-Shaping” button doesn’t seem to be working as the “In” indication never turns on. Does anybody know where I can find these buttons? British audio only shows one push button on their list and I don’t know if it’s the same. I haven’t pulled this thing apart yet to see if there is any markings on the button that is still there. Thanks in advance
