Axiom Home Page Forums General Discussion Technical Questions Sub Connection

Do you mean the 1/4" phone plug? The sub should have come with an adapter. It looks like a mono headphone plug on one end, and the female RCA on the other at a right angle.

You connect your sub cable to that, and then insert the phone plug into the jack on the sub (make sure it's in all the way).

Axiom did this, because the straight-in RCA jacks were the most often thing to break on the older design. This way there's a more solid XLR/phone jack, and the RCA is at an angle.
