I have Marantz sr5200 amp and Mission fsav2 speaker set which arrived only yesterday. I've spent all night setting them up and when I goto test mode on the amp, all the speakers sound fine, but nothing from the sub. I've tried just about everything, nothing. One thing I have noticed is that I cannot change the sound on the speakers higher then 15db. Is that normal? I am not sure if is it an amp problem or the sub! Can someone perhaps tell me what the menu setting should be? I don't know what to do!
