monitors in mono problem
bought a pair of Yamaha HS7 monitors. I bought a stereo 3.5 mm jack to duo stereo 6.35 mm jack adapter to plug into my audio output from my Mac mini.I bought 2 stereo 6.35 mm jack to jack cables out from the adapter to the balanced inputs of my Yamaha speakers.The speakers work but everything is in MONO ????
Any help please.
