So, maybe this is a dumb question, however, I'll give it a shot... I installed a Yamaha HTR-5960 Receiver in my Family Room (along with a Sony LCD and Directv HD-DVR). How come my volume levels are showing in negative decibels? Shouldn't 0 dB be absolutely quiet and positive dBs be louder? I routinely watch the TV at -40 dB on my receiver. What gives? Did I set something or configure something incorrectly? Thanks for anwering a newbie's question!
