Sub woofer not working on SR7500

[BMiester]

Hello
I'm having a bit of trouble and would love some help. I can't get my sub working when playing CD's on my DVD player.
The amp Marantz SR7500 display shows the front left and right speakers only but not the sub. I have enabled it in the menu.
I love my sub. Please help
Cheers

Set all speakers to Small, Xover to 80Hz and sub to On. Works on my SR7400.

CD-Audio is 2.0, not 2.1.

You can like barrybarwick, or set the sub menu to "both", or use a sub with high level input like REL, BK or MJ...
