Using Stereo L/R ( LF/RF setting) and C,SR,SL,SBR,SBL with Stereo L/R set to large and all other speakers set to small, no sub. All bass will be re-directed to Stereo L/R and in turn thru my sub?
Yes, but expect the LF/RF signal to be attenuated to provide the necessary headroom. Check your speaker levels with a calibration disc, and try to provide any necessary boost external to the Oppo so that you don't risk clipping the LF/RF input at your preamp.
If the Sub is OFF and LF/RF are Large then both LFE content and bass steered from other, "Small" speakers (according to the crossover) will be steered to LF/RF.
If the dedicated L/R stereo outputs are re-assigned to act in place of LF/RF, then the same thing happens there.
Note that if L/R are left in their normal, independent configuration, then LFE is discarded in the down mix to stereo on the dedicated L/R for x.1 tracks.
Note also that all audio processing, including down mix and bass steering is disabled when you have DSD-direct-to-analog conversion active while listening to SACD discs. So if Sub is OFF, the .1 channel of any SACD discs will be lost. So use SACD Output PCM instead of SACD Output DSD. Of course quite a few SACD discs simply don't use the .1 channel in their 5.1 layer, so no problem for those.
