Sir Boa,
I am indeed using a Y connector to make the connection to the sub(Velodyne Model CT100). The receiver does have a sub on and sub level adjustment which I did tweak. According to the Receiver's manual....it should be hooked up to PreOut Sub instead of Subwoofer input. I wonder why it would have two Subwoofer hook ups to begin with. The one thing I haven't done is test the cable I bought(new)with another component.....DOH...lol.
