Recently purchased Integra 6.3 receiver..1st question is do you leave receiver in "stand by" mode all the time??? My thoughts are yes, but unsure...and why when i run tv thru receiver and into speakers do i need to lowere the tv volume to zero..Why doesn;t this happen on its own..I have a Hitachi 57" , Integra 6.3 and an Integra 5.3 dvd changer with RBH speakers Thanks in advance...I am a newbie to this "home theater" chit...
