First, are you unable to connect the “SWOOFER” pre-out to the subwoofer or are you just not getting any sound of the sub?

Basically you want to connect from the “SWOOFER” pre-out to the subwoofer (probably called “Line in”) with the RCA terminated cable you have described. (like Rick posted ;\) ). If that isn’t an option then:

What type of subwoofer do you have?

How are the connectors on the subwoofer labeled, if they aren’t labeled what do they look like?

What other controls are on the subwoofer?

Did you go into the receivers menu to make sure the sub is receiving a signal?

You probably have to “tell” the receiver that you have the sub hooked up if you didn’t run some sort of Auto-setup that does it for you.

Not sure how those menus are arranged but it’s probably in “Speaker Setup” or something like that. Likely it’s just a simple “Subwoofer” = “yes” or “no” type of option

Always one step ahead Rick.

I've got one of those EP350 amps. I had a similar problem until I twiddled with the adapter to some degree.

Double check it with a portable player of some kind directly connected (headphone out->sub in) or with your CD player (same deal, right channel out directly the sub) to verify that it makes noise.

I wonder why Axiom doesn't use the industry standard connection on their subs?

What Alan/Ian/Peter said awhile back was that the most returns/repairs they get on subs are with replacing those RCA jacks, since they get broken off all the time. So they replaced it with the 1/4 adapter.

1/4" jacks are very sturdy, I don't blame them. RCA is still better than the 1/8" jacks, those things get eaten alive with an accidental tug.

Hi KSTx,

Be sure you shove the 1/4-inch phone-to-RCA female adaptor all the way in and make certain it makes good contact. It should sort of click when it's properly seated. Rotate the 1/4-inch adaptor to ensure it's not loose.

Go into the AV receiver's menu and be sure the subwoofer output is "ON". INcrease the sub output level to +2 dB. Turn the subwoofer's own volume control to about halfway.

You can verify if the subwoofer amplifier is working by inserting just the tip of the 1/4-inch phone adaptor--you should hear a loud buzz from the subwoofer.

Regards,
Alan

And it's a little frightening, too!

Alan,
I went through exactly what you said. The RCA cable is hooked in the adaptor and it is solidly plugged in. I then went through the set up procedure and was not getting any sound through the subw. I've checked and said yes to subw in setup, set to +2 and nothing. I guess my next question is, do I have it plugged in right on the back of the AV unit..R872? Connected to the Pre Out SubWoofer? By the way the was it is set now there was no loud noise like you would get hooking up a jack to an electric guitar for example to its amp.
