Receiver to Amp 12v trigger cable causing HUM... (1 Viewer)

[David John]

I have a Yamaha Rx-v1200 and an Adcom amp for my subs and rear surrounds. I'm getting an annoying hum when i have the 12v trigger cable hooked up.

When i unplug the cable, the hum is gone.

Any suggestions on how to eliminate this hum?

Right now I have a simple 1/8 inch 2 conductor cable.

Does anyone make a better cable for this?

Maybe one with a high quality shielding?

Or is this a more complex problem?

Any suggestions are welcome.

Thanx.

Dave.

David,

It may be just a ground loop. Try a cheater plug from Radio Shack...see if it goes away. Cheater plug...takes the ground off...3 prong to 2 prong.
