I just received my system including the R872 7.1 AV. I'm tring to hook up the sub but apparently I'm not doing it right. I'm connecting to the pre-out SWOOFER and the male end fits only the XLR/1/4phone in. If I pull the 1/4 out it doesn't fit??? Need assistance to make sure I'm doing this right. Any one up for providing assistance tonight?

What kind of cable are you using (RCA or XLR)? What type of sub?

Its not an RCA type plug. It is a rather thin cable, I would have to say it is more like 3.5 mm, it has a small center male plug and a surrounding shield that would say fit over a female plug. Make sense?

Can you take a picture of the pieces for us?

OK it is the RCA sub woofer cable on the web page under cables sub woofer coax cable.

EP350 Sub

Anyone have an answer?

I don't have an Axiom sub but there will someone along to help.

From the manual:


RCA LINE IN: Your subwoofer is shipped with a supplied 1/4” Phone-to-RCA-jack adapter already installed in the XLR female input. Connect a shielded coaxial cable, with male RCA plugs on each end, from the A/V receiver or A/V preamp processor’s Subwoofer Output jack to the RCA female jack on the 1/4” Phone-to-RCA adapter.

I would say use the adapter that was supplied and the coax cable, sub cable, you have.

With the sub cable plugged into the sub out of the receiver to the sub in, using the adapter, to the sub.

Thanks Rick, that is what I did and I'm not getting any sound. System is on, all of the rest of the system is working. I'll check it out again.
