Hi Dan,

I'm just speculating since I don't own a Denon, but I think the second remote might be to use in a "second zone" like the bedroom or patio or something. I'm pretty sure you'd need an infra-red repeater in the 2nd zone wired back to the Denon to pick up the signals from the 2nd remote.

I think my H/K AV receiver came with two remotes as well. I've never used the 2nd remote because I don't have a second zone. .

Regards,
Alan
