I've been away from audio stuff for an embarassingly long time, and have an embarassing question. I'm upgrading my system, and have acquired the following stuff, largely based on opinions expressed 'round these here parts: Denon 2801 A/V receiver Sony SA-MV40 subwoofer Home Theater Direct Series Three front and center, series Two rear speakers A high school student apparently far more knowledgeable about this stuff has been helping me connect stuff, but he tells me that the output to the subwoofer from the 2801 can't be connected to the subwoofer because it uses a different type of connection. I've craned my head around the back of the receiver (other problem: I've lost the 2801 manual, and, while you can get .pdf manuals for just about everything under the sun, Denon doesn't have a 2801 manual available as a .pdf file), and it looks to me like the subwoofer out from the receiver is an RCA plug, whereas the Sony seems to take a bare wire input. I think that the HTD stuff should be fine - they just clip into the Sony, or screw into the Denon. Can someone tell me what the thing to do here would be? Are there RCA to two-stranded wire speaker cables available? I can't believe that this receiver and this subwoofer can't be made to communicate. Thanks, J.
