I would like to know how to best connect my Velodyne subwoofer (says 806/907 on manual) to the Onkyo SR605. I see that on the back of the 605 there is an IN for only one wire, but on the back of my woofer, i have a LINE LEVEL L and R input and L and R output. What cable do I need to connect my woofer to the 605? Thanks!
I don't see any such Velo model, but common practice is to get a single line audio cable with a male RCA connector on both ends. Connect to the sub out/lfe out on the AVR to either the left or right low level input on the sub. According to some, as seen in this thread, Velo recommends getting a "Y" adaptor, supposedly included with the sub, and connect to both the L and R input.
You can get both the cable and the Y at Radio Shack or Best Buy, or other electronics or audio store.
