I have the Harman Kardon AVR7200 and was wondering how to tweek it for H/T listening?? I have Bose 701's up front, 301's for rear surround, AM5 for back surround and the VCS10 for center channel. What do i need to do to get the center volume louder in movie mode?? I know this receiver has enough power. Also i am using all Monster Cable and have Monster Coax on the Onkyo DVD player. Should i use Optical? Do i need to buy a test disc?? Please help, i feel i am being short changed.....
