Allen and Heath xone 23 purchased and misplaced the factory power cord so I bought a universal one from best buy and used it for a couple years.  Recently tried to use it and im not getting any sound, power comes on but sound isnt coming on, it could very well be my cheap sony stereo its hooked to I just dont know and I have no way of testing it I dont have anything else to hook up to it so im not sure.  My gut tells me its my stereo, but I just dont know.  This would be perfect for someone who knows how to work on these, I guarantee its something small and bam you have a brilliant sounding mixer.  I was wanting to try a pioneer just for the effects so Im parting ways with this one as is.  If you have any questions contact me through the platform and i will answer them.
