spencersmb Posted April 17, 2019 Share Posted April 17, 2019 Hey all, I just got my new system hooked up: Denon 4500h, Emotiva XPA-5 Gen3, 11 speakers - no sub yet. I have the 3 front speakers + 2 surrounds coming from the amp, the rest are hooked up through the AVR. I'm watching game of thrones streaming through laptop -> chromecast and noticed a slight hum the the 2 surround speakers (rp - 500's). Only noticeable if there is a quiet scene and year head is next to the speaker. The front speakers have no hum I can hear. Any ideas what is going on? Thanks, Spencer Quote Link to comment Share on other sites More sharing options...
wuzzzer Posted April 17, 2019 Share Posted April 17, 2019 Is it a low frequency hum or high frequency hiss? Low frequency him would be a ground loop. Try a different outlet for your receiver and/or amp. Are you using shielded RCA cables? If it's a high frequency hiss, very common with Klipsch due to their high sensitivity rating.

I think it's more of the high frequency hiss because it comes out of the tweeter. I can't hear anything coming from the copper cone in the speaker... Of course this is when my ear is right up on the speaker, but when I move a foot away I can't hear it. Obviously not a realistic scenario but you know us audiophiles! Thanks for the help @wuzzzer 1 Quote Link to comment Share on other sites More sharing options...
