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

Thanks @jayctoy |
I would try a different circuit breaker when you change the plug for the TT, not just another outlet. Is it possible to turn the plug in the wall socket, sometimes changing the polarity will help (I have older TT's, always the first thing I try)? If the plug is "keyed", one wide one narrow blade you will not be able to do so. At the hardware store you can buy an inexpensive outlet tester (everyone should have one), it will look like an extension cord end. It will have LEDs on the back and the combination of the lights will tell if the wiring is correct, polarity, ground, etc. You probably are hearing 60 cycle hum, which is the frequency of A-C power. One outlet or lamp wired incorrectly, motor loads, nearby un-shielded transformers, bad ground or voltage on the neutral.....BTW some MM cartridges are "sensitive" do you have another to try? good luck |
