OK, I am running klipsch reference 7.1 with rf-82's as my main, emotiva xpa-5 linked with my onkyo tx-nr717. Well last night after the walking dead my fiance notice a static sound from the left speaker and hardly any sound. I swapped speakers and same thing left speaker hardly any sound and static so it is not a speaker issue. I check all banana plugs, all connections from amp to receiver and everything and ive still got this faint buzzing/statics. My main surge protector is in the top plug behind my tv wit the tv, onkyo, bluray, xbox ect plugged into it and the emotiva is plugged into its own surge protector that is plugged into the lower plug behind the tv in the same electrical outlet as the other surge protector. HELP!!!!!!!!!!!!!!!, lol.

Don't panic. First just turn the amp on and nothing else. See if the problem still exists. Then turn on the reciever. Then try swapping speaker wires to rule out the wire. Then try it with JUST that wire hooked into the amp. If you have a spare power plug try that on the xpa-5. Also, emotiva reccomends strongly plugging the xpa-5 directly into the wall bypassing a surge protector. Emotiva has electric protection in built and have found that some surge protectors/line conditioners can limit the dynamics and sound quality when powerful very quick surges of current is needed. (This shouldn't fix your problem though). If I was you I would also plug my AVR into the wall but that's just me  Having done all that and it still doesn't work... 1. Have some salted peanuts and beer. 2. Grab your nearest towel. 3. Hail the vogon construction fleet orbiting earth. But have some poetry on standby. 4. Call Emotiva (not email) |

Try running the speaker off of your receiver, see if it still does it.

I had an issue like that in the past, it took me a long time to found the problem because it was intermittent, finally it was simply a bad contact inside the RCA cable plug that make electrical micro spark between the plug material and wire (cracked solder), sounds like static in speaker. Just trying others RCA cables between your Onkyo and the XPA-5 or switch cables to compare.

Or what you call static, could be a hum (ground loop), you can find a ground loop by disconnecting one by one the interconnect between your Onkyo receiver and all your sources (TV, DVD, BD, satellite or cable receiver, tape, VCR, etc.)
