Running a sub in 2 channel with dhc80.2

Could it possibly be that I am using balanced connections for my fronts, rears, and center, and a single ended connection for my sub? Maybe I should hook my sub up with an xlr to rca connection and see if that works. Would that make sense?

What does the setup display show for your speaker configuration? eg - did it detect a sub when you ran Audessey?

Does the sub work when you listen in mult-channel?

Hey erik thanks for the reply. Yes Audessey did detect the sub and it does run in multi channel. It runs in all channel stereo just not in stereo. Just cant figure it out.

Does the Integra have multiple memory settings?

If so, maybe a 'work around' for now is to select "All Channel Stereo", then manually turn off the center and surrounds, and save the setting.

Maybe what you are experiencing for 2-channel stereo is 'normal' - i.e. - if your source is only 2-channel (L/R analog connections), then that's all you get out of the Integra?

Possibly, I just find it unusual that the onkyo equivilent has the ability to run a sub in 2 channel stereo. I am going to see if it has multiple memory settings and if so I will do what you suggest in regards to turning the center and surrounds off. Thank you very much for the suggestion.
