What input are you using on the Sony?
Hum in speakers
Hello all
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.

Set up is:
- Sony STRDH190 2-ch stereo Receiver
- Warfedale Denton 80 Speakers (16 g speaker wire)

Try using the phono input on the Sony instead of the internal phono on the Technics. The speaker wires do not have to be bound together. BTW, you do not hook up the ground wire if you are using the internal phono on the Technics! Note • When you connect a turntable with a PHONO/ LINE switch, be sure to set the PHONO/LINE switch to PHONO. • This receiver equipped with Phono Equalizer amplifier to meet MM type PHONO cartridges. MM type cartridge used on turntable have a variation of audio output level. In case MM type cartridge output is small, you can use phono volume offset to increase the level (page 28). • To record the sound from the receiver, you must connect your device to the AUDIO INPUT 4 OUT jacks |
