Hi everyone, My QSC PLX1602 is becoming less and less reliable (even after two trips to the shop) and I've decided to replace it. I'm considering the Peavey IPR-1600 which would be used with an SWR Grand Prix preamp and one or two 4-ohm Acme Lo B-2s (depending on the volume level of the gig.) My question is: when I'm using both cabinets can I use the Thru/Out jacks on the IPR-1600 to run in dual-mono mode? If I understand the IPR-1600 correctly I could run a 1/4"-terminated cable to connect the channel A out to the channel B in. Or should I find a Y/splitter cable and use that to drive both inputs? Edit: hmm, the manual says that the Thru/Out is 1/4" unbalanced tip/sleeve whereas the input is 3-pin XLR or 6.3mm, which I assume is tip/ring/sleeve. Hmmm.
