Hey all, I purchased an XPA-5 to power my home theater I was planning on running my fronts center and surrounds off of it and my rear surrounds off my reciever. I have: RF-82ii RC-52ii Rs-52ii I hooked everything up and everything sounds great, Much more powerful, the speakers sounded much better than when connected to the SR5007. My problem is that when I pause a movie or listen to 2Channel music, There is a Hiss coming from my RS-52ii which I can hear from my listening position. When I put my ear to my center and tower speakers there is a hiss as well, however I cannot hear it from my listening position. To solve this problem I just hooked the RS-52 back up to my receiver. With all of the speakers connected to the XPA-5 the distortion issue I was having with COD black ops 2 was almost completely eliminated. However with the rear speakers hooked up to only my receiver the problem still exists. I have also disconnected everything from the amp and just had the speakers connected, the hiss is still there so I know that its not coming from another component. Does anyone have any suggestions on how to eliminate the hiss or is it just something I have to live with? I have a limited knowledge of electrical engineering, but I was thinking if I hooked up a resister in line with the speaker cable this would increase the resistance and make the speaker less sensitive? not sure how that would effect the components of the speaker though. Any advice is appreciated.
