Hooking DishNetwork receiver to amp=speaker noise?

If you have an optical input available, try that.

Optical won't complete the ground so no 'loop'.

Now, on the Dish receiver, go to the menu and 'system setup' than 'audio setup'.
Get rid of the night volume leveling and set output to PCM only.

I have had this same experience when directly connecting the audio out (L&R) from an aging 301 receiver. The condition was not appairent at first but presented itself after years of operation. After a little trial and error I found that it was an internal ground loop due to aging components in the Dish Receiver. The telling tell was that hum was present even if the Dish receiver was completely disconnected from everything. The moment I plugged in the interconnect cables from the intergrated amp into the Dish receiver, the hum was back.

I solved the problem by going to a new Dish 211k receiver with an optical output. As Brianmgrarcom said, the sound is better/acceptable, but not spectacular.

I had the same problem - cable box RCAs or TV RCAs into my integrated amp caused a hum. Much more apparent on the input I used, but still present regardless of the input I used.

The cause was/is different ground points being used for the cable wire and my system (aka ground loop?).

I got a Jensen Cable TV RF Isolator. Zero noise now. Costed about $60.

Googling it, I just saw on the website that it says "This unit will not work with satellite systems."

I'd imagine their are ones available for satellite systems. Also as has been mentioned, use an optical connection if you can. This is the driving force behind optical, as there's no electrical signal being passed.
