I have what is probably a common probem for people with home theatre systems. I set the volume appropriately so I can hear the dialog but as soon as music, gunshots, explosions etc.. come on I am frantically reaching for the remote to turn down the volume (family sleeping up stairs). I've tried cranking the volume on the center channel speaker and that's helped a little but I'm still constantly turning the volume up and down. My tuner is a 4 year old Denon AVR-485. I've got 2 column speakers, a center channel, 2 rears and a sub (Boston Acoustics, Definitive sub). Can I set my tuner up to take care of this or is there a piece of equipment I can buy? Any feedback would be greatly appreciated.
