Thanks. I bought the Mackie Thump 15s, but I do not see any switches to switch inputs into the speakers. I am using the same cables which are from the controller directly into the speakers. I am confused as to why adjusting the mic volume on the Wego is causing a hum from the speakers when they are not plugged into the mic connector on the controller.
The reason I was thinking it is a laptop issue was because I recently installed El Capitan and though maybe that changed the audio settings for the Wego. I reinstalled Serato and restarted the computer. Also while it recognizes that the Wego is plugged in, it is not showing the audio in and out volume controls.
