Sub woofer output

[Eldoman]

I have a Siny receiver DE-697 that has a subwoofer output. I hook it up and nothing comes out. Is there a setting within the receiver I need to change?

You need to go into the speaker setup menu, turn the sub out to yes and set the level.

You should go through the full set up if you haven't done it before to get all the speakers balanced. The sub level should be set by ear not using the same noise as the other speakers.
