Would that be a good option? Looks like it

Just wondering about this ground loop issue when using the original amp... I haven't looked at the schematics yet, but I'm not sure I understand why it's happening in the first place. WMS managed to power the amp from the same PS as the PC in the original design, so why are we having the issue with the nucore setup?Eric A. wrote:Actually I forgot about the ground loop noise that will occur if you use the original amp with the nucore computer power supply so you will need an external computer power supply for sure if you want to use the original audio amp.

Beyond using a ground loop isolator between the sound out / in, anyone come up with another way to solve this?

Perfect explanation, and what I figured was happening. Guess I'll install my amp tonight and see what happens!Chuck wrote:Doug,
The ground loop issue doesn't always occur. I believe it depends on the power supply used in the machine. The original amp received audio data in digital form and decoded it on the amp board. By jacking in to the amp board you are bypassing the digital section and you can get a ground loop situation.
No. Amperage is too low. We use a power supply like that for our amp that has much higher power output. I think it runs about 25 bucks.
