If I play a CD on my 950 in two channel stereo mode, does it cross over my sub at 80 Hz, and only send above 80 to my speakers and below 80 to my sub ?

Or does it send a full range audio signal to my Left and Right and then also send a full range signal to my sub??

I seem to have too much bass with 2 channel stereo on the analog CD setup.

Thanks for any info,
