First off I am serious newbie here, so I apologize if my question is not phrased in a way that makes sense... I recently purchased a Denon 1804 after moving up from the very reliable but OLD Sony AV1020. My Question is, for some reason, when I am listening to the Dolby PLII, or DTS, or Dolby Digital EX formats, I am not getting any signal to my subwoofer (Velodyne DPS-12). I get a signal when I am in the Stereo, Virtual, Direct or 5/6 channel setting, but with the other I get nada. Do I have something configured incorectly or what? When I set it up, I set up the Front Speakers, Surround Speakers, Center Speaker and Sub. Hope that makes sense. Thanks in advance!!!
