Possible Cause for Hisssing and Buzzing Found.

[Nolan B]

Let me first just say while I found the problem I dont know the real reason. I had never had any hiss or buzz problems from my RSX 1067 in the passed. The only sound I got was a very slight hiss if I had the volume turned up to max with no source. Basically it was not an issue with me. Last night all of a sudden that changed. Out of the blue I got a metalic hiss which to me sounded like what a dog must hear when a dog wistle is blown. It was horribile.

Below you will see what I have in my current set up and where its all plugged into which all runs off a single breaker (15). As it turns out it was ulitimately a power issue Because the ONLY thinng that changed in my system that day was adding a printer to the mix. Even with the printer turned off I still got the buzz (I assume some power is still used), but when i unplugged it the noise immediatly went away.






Plugged into the Belin Pure AV FP 30:

RSX 1067
RDV 1060
iScan HD
XBOX 360
Cable Box
42' Plasma

Comming from the same socket as the FP 30 this PF 30L had the following. The only other thing running off the breaker was my PV1 Sub on a seperate outlet.

MAC Mini
20" Mac LCD
12 volt fan x2 running for RSX 1067
RF Remote repeater
Wireless Modem


The instant I added the print (even when turned off) the hiss/buzz started. It apears that in my case it was cause by a lack of or faulty power.

I plan on buying a Power Conditioner that lets me digitally see how much power is being used for each outlet to do a little experiment. Anyone know if the new rotel power conditioner will have this option?

The moral is if you have a hiss or buzz it COULD be that to much is running off one breaker in your house. Have a look,

yes, I also had a buzz with my 1068 & 1095. It was driving me nuts. Not a buzz coming out of the speakers. But a buzz from the 1068! Disconnected, reconnected everything. no luck. opened up the outlets and made sure they were grounded. No luck. Connected the 1068 to other outlets, even took it out to the damm garage! Still buzzed!

Lo and behold, we just bought a new humidifier for the bedroom. What made me think of this and try it?, I dont know. But I turned the humidifier off AND...no more buzz!! AND, the 1068 only buzzes when the humidifier is on low. So now we run it on high all the time and I have to refill it every day! small price to pay to keep my 1068 from buzzing!!! :T
