Alright, I'm not sure if this should go here or in hardware as I am somewhat new to all of this. Anyways, I am having an issue with what I am guessing is my receiver. I have a Pioneer VSX-D814, hooked up to that are two Wharfedale Valdus 500s and the Valdus Center. When I have it set to Tuner, the speakers sound great at about -75 to -70. But If I have it set on TV/SAT, DVD, AUX(PS2); I have to have it cranked up to -20 to get any real amount of sound out. And at that level the speakers hiss pretty bad and I can barely hear anything out of the Center. Now since they sound great while listening to the radio, I am assuming that there is something I need to do to the receiver. I've read the manual front to back about 5 times, and messed with the thing more then I care to remember. So what should I be trying to do here?
