I have my beocenter 7000 hooked up to two big speakers, which I use to listen to music through my phone and iMac as well. But recently I noticed that Space Oddity sounded really high, i checked the speakers, and the one on the right is really silent. i tried both speaker outputs, both speakers, they each work, the problem definitely lies with the output/turntable. The phono works fine and uses two speakers. Anyone know how to fix this?
