@Bond 007 - Sorry for the tardy response. I want to thank you for your guidance. I now have the sub working some. Still needs some tweaking but she is BOOMING ! I will need to turn it down some because my neighbors will not be happy with the shaking. I have the LFE all the way up. I have the sub @ 80 Hz. The volume on the center, front L&R and sub are all at the midpoint. I will send you the specific settings when I am back home. Prior to this setting when I ran the YPAO I was getting a W-3 error message. There after i did the manual adjustment I mentioned above. Haven't ran YPAO since. Is there a recommended setting for the volume on the speakers and sub? Just hope I am not overpowering the speakers/sub. Again, newbie and learning as I go.
