I took a quick look at the specs. for the Denon AVR-1910 and I did not see any analog pre-outs for L&R (or center and surround) speakers. The only analog outs I see are RECORD/TAPE which will not work because they bypass the volume control, and a zone 2 output which may or may not bypass the volume control.
You can try the zone 2 output to see if it works, but that may bypass some of the other features you want from the HT receiver.
I think you may need to consider a different HT receiver or a simple 2-channel pre-amp if you don't need HT functionality.
