I am new to the club. I just purchased two RTi10 fronts and a PSW505 sub yesterday. I am running a Sony DA50ES receiver. I am wondering how I should connect the sub. The receiver has two sub-woofer pre-outs. The PSW505 has both a L and R input as well as a LFE in. Both ways seem to be working. The Sony manual says to connect to the Active woofer audio in. It doesn't give any more information. Which inputs should I be using on the sub?
