Yes, but the 2802 will only support 5.1. First run six analog cables from the source to the corresponding six "EXT IN" jacks on the upper left side, next to the antenna terminals.
Once the source is configured to output to these outputs, you select them on the 2802 by pressing the "EXT IN" button on the remote. This will totally bypass the surround circuitry in the Denon and you may have to fine-tune via the source.
