Turntable ground loop

May 28, 2020 · In theory ground is ground - 0V. Connecting all grounds together is mostly good, but what you don't want is connections between grounded wires, except at the one grounding point - connections elsewhere, in addition to the grounding point, form a ground loop, and commonly hum. Think of the grounding point as the hub of a spoked wheel.

It is usually a 60HZ freq. Your noise is high freq around 2KHZ or higher. What changed in your system recently? Any chance you added a turntable or started using Traktor or Serato with your turntable? It sounds like the same 2.5Khz tone that comes off the control vinyl. Oct 21, 2017 · What is generally called the ground is actually the return path to form a complete circuit. When the shield of one of the phono cables is used as a ground (return path) for the chassis of the turntable, there is the possibility of unwanted electrical noise, RFI/EMI that is picked up be the chassis to be imposed on the audio signal. If a ground loop arose, clearly an optical connection to a DAC would break it. There isn't an analog signal path between Line-In and Line-Out, but they share a common ground. I'm not convinced there's a loop. In fact, given that the hum's only an issue with the Line-In one suspects that it's being introduced into the ground from the turntable.

The problem is that when the two are connected I am getting a hum from the OSD. They are both connected to the same outlet so the usual cause of ground loop hum (being on different circuits) does not apply. I am wondering if there is some way to use the turntable ground connector on the Denon to stop the buzz.
One of the sources of such noise is a ground loop or when grounds on different pieces of equipment are connected, leading to a loop. Digital coax is less sensitive to ground loops but they’re susceptible to electromagnetic interference or radio frequency interference. Optical and digital coax are similar to each other in sound quality.

If you can figure out how to temporarily add a separate ground wire from the tonearm to output ground you may get your answer. To do this, simply connect the "ground" lead of the meter to the earth "ground" pin of your a.c. socket, then connect the other meter lead to the "hot" pin of your a.c. line. You should read between 115 to 125 volts a.c. Next, move your "hot" meter lead to the "neutral" pin of the ac. line. HifiHut.ie - Ireland's leading supplier of HiFi & A/V Plugs & Connectors.
