I am trying to set up a modest audio system and cant figure out why there is a hum when I turn the volume up past 55. It only happens when there is vinyl spinning. If I turn volume up without vinyl on there is no hum. Below 55 volume the hum is not there.
note: I did set the speaker impendence to 6 ohm via the receiver settings.
Set up is:
- Sony STRDH190 2-ch stereo Receiver
- Warfedale Denton 80 Speakers (16 g speaker wire)
- Technics SL-1500C Turntable
