I just purchased this subwoofer and am trying to set it up. I have a question for anyone that has the DD series sub. On step 8 on "Onscreen programming and setup" in the manual it asks you to raise the volume of your reciever until the DD test sweep can be heard from your systems speakers. What test sweep are they talking about? It it that static test tone in the reciever that travels from one speaker to the next? Any help would be appreciated. Thanks!
