This is my first time owning a Fractal product. I borrowed an AX8 from a friend last week and LOVED it! Worked great, no problems. I found one on Reverb in mint condition, bought it and just got it today...no sound through my powered speaker. Same gear/connections as the one I borrowed, the meters show input level, VU meters show input, all of the blocks are connected, but no sound. Any ideas? Thanks!
