Axiom Home Page Forums General Discussion Technical Questions ep350 no sound

Hi everyone

I just traded up subs from the ep125 to the ep350 v3. I got the 350 yesterday and when I plugged it in it was receiving power (green light) but there was no sound coming out. I'm using a coaxial cable attached to the provided phono adapter and plugging that into the sub. This cable does work with the ep125 plugged directly into that sub's line in (it's an older model).

The receiver doesn't see the sub when I run the auto calibrate. Also I tried the white nose sound level testing on the receiver and I can only hear noise when I attach the ep125.

Does anyone know what might cause this?
