Hello guys, well I got a 3B amp to replace my NAD 2200 and , I can't get no sound out of it!, I took the Nad out and plugged everything just like it was, but nothing, the green lights come on but no sound at all ! , well I actually get a weird sound from the speakers when I turn the amp off. Any advice??? Thanks. I am using a Marantz 7002 as pre.
