I was recently given an SX KN700 keyboard and cannot figure out the power situation. I bought what I thought was the correct adapter but it didn’t fit right. When I took a closer look into round hole, it appears that there is not a female connection. There is square opening for an adapter next to the round one. Is that an adapter I should be looking for? None of the photos for SY AD7 show what the “plug” looks like but the AD6 looks like the one I have.
I don’t want to keep throwing money at a keyboard that may not work anyway but any advice would be greatly appreciated.
