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.

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 

 

 

128x128defandum

When I set up the speaker wires I removed the outer casing that housed the red and black wire. So the red and black wires are not bound together....I'm wondering if that could be the issue

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

@yogiboy nope, same thing...this is so frustrating. I had a lesser quality turntable (audiotechnica lp60xusb) set up before this and didnt have this problem. I just dont get it
