I just bought a 2016 Eden WTP-900 to replace my Navigator + WT1250 that was stolen. I have an odd configuration of 3 cabinets: 1 4ohm cab and 2 8ohm cabs I've been mixing and matching them in my WT1250 with no problem, but I understand the WTP-900 has lighted posts for specific configurations. This is copied from a 2016 post by seabreeze explaining the different options that light up when you press the "cycle" button on the back (I'm assuming it's accurate.. i don't have my amp yet!): 8 = connect an 8ohm cab here 4 = connect a 4ohm cab here X = do not connect a cab here In stereo mode: l:8+8 r:8+8 OR l:4+X r:4+x OR l:8+8 r:4+X OR l:4+X r:8+8 In bridge mode: l:8+X r:X+X OR l:4+X r:4+X OR l:8+8 r:8+8 Question 1: Can I run bridged like this? 4 + X 8 + 8 It seems that in bridge mode, cabs within a channel draw in parallel (so 8+8 --> 4ohms), and cabs between L/R run in series, so 4L + 4R --> 8ohms. In that case, it should be just as happy with the configuration i proposed, right? Question 2: Can I run in stereo mode like this? 8 + X 8 + X OR 4 + X 8 + X This is most important for me, as this is the way I intend to use it most of the time. Since the channels are independent in stereo mode, and the connects are definitely set up in parallel in this case, and since the amp can handle a 4ohm load, I don't see why it would mind only having one 4ohm. Question 3: If i have it set to this in bridged mode: 8 + X X + X What happens if i set it up this way with single 8ohm cabinet, but plug it into one of the other outputs? will it make a difference? Essentially I think I'm asking whether the cycle button actually does anything internally, or it is only to tell humans what configurations are ok? Many thanks to anyone who knows the answer!!
