Yesterday I noticed a noise coming from my speakers when no source is playing and the volume is fully turned on. It is a mixture of hiss and hum. I checked all my wires and they all are securely connected. Suspecting it on my DBS system, when I unhook the audio input coming from DBS the humming noise stops but the hiss remains.
Any ideas how to deal with this situation. I am running Denon AVR2802 as PrePro along with Carver AV405 multichanel amp. I tired hooking my speakers directly to denon but got the same results.
