Someone must have been moving around behind my EP 500 (It's about 18 inches out from the corner) and must have run into the subwoofer connection. It hasn't broken off, but moves easily and I don't get any sound.

Luckily my MMC has an xlr connection. I'll look for a cable today at ratshack.

Will I need to recalibrate the new connection?

I think you are able to use the RCA out connection for an input if my memory serves me right.

Hi bugbitten,

Hutzal is correct: You can use the RCA line-level output on your EP500 as an input connection, since they're electrically linked inside.

Regards,

Yes. The outy works the sames in the iny. Hurray!
