White noise" problem...RMB-1095...
I have a "noise" in tweeters and mid-woofer looking like a white noise. I tought it was a ground-loop, but after regrounding everything with an electrician AND the Sat technician, it's not. Cheater plug don't works, and lifting all the common ground is not working to. So NO GROUND AT ALL is still doing this mix of hissing and humming.
I have a Rotel RMB-1095 for amp and Yammie RX-V3200 for pre-amp. After 7 hours (yes 7 precious hours of my life) of unplugging everything, then starting 1 cable at a time, I discovered that with ANY source (DVD-player, CD-player) at a time, or all together, and only the Sat decoder not in there, I'm in silence heaven. But if I only plug the coax feed in the sat decoder, and then ANY cable from the Sat decoder to the pre-amp (S-Video, component, digital coax, RCA), and 1 at the time only, I always get this "white noise" that I ear at 10 feets from any speaker!!!
The Sat decoder tech is telling me that the amp is amplfiyng video noise, and the amp tech tell me it's the Sat decoder's fault. The sat technician tell me that he cannot do anything for me. Rotel and Rotel dealer are telling me it's the Sat company problem. So I'm stuck, and really tired of trying to solve this problem.
It's not a ground-loop. So what is it, and how can I solve this?? I'm really desperate here. Please. I've swap 3 different satellite decoder, and 2 different company with the same results. I've run a cable directly from the Sat antenna to the decoder across a window to avoid ctaching noise from the house. I've add a HTS-3500 with same result, add a 20 A dedicated circuit with same result. I've swap all the cables (all of them!!) with same result.
I really think the Rotel is amplifying a noise or something, because with only the Yammie, I'm in silence heaven. I've try a 2nd Rotel with same result (I had to take this 83 pounds back for nothing arrrgghhh).
Just reach my dealer. He says it's not the first time he hear a story like this. He tell me it's the Rotel and Sat decoder association that is bad, and that the Rotel is amplifying ground noise!?!? Here is the solution he is offering me:
1) Putting aluminium foil (or any conductive "paper") around all interconnects between the pre-amp and amp and jumping and grounding this aluminium (or conductive) thing. Really?? Wow!
2) Buying a new pre-amp with XLR balance input/output. I don't really like this idea, lot of money not put aside for this...
Is he kidding or the aluminium foil idea can actually work. XLR could really make a difference here??
I can't change my satellite dish because I live in an isolated region, and the only way to get TV and HD-TV is with a satellite dish (cable cannot reach my house).
I'm a pharmacist for god sake!!! Not a sound engineer!! All this money for this. I'm so disappointed.
