I'm a proud owner of an SP404sx as of this afternoon and I plan on using it for making beats and such but I'm most of all looking forward to using it for vocal effects onstage with my band.

I know I have to get RCA cables for the outputs, but what should that connection be connected to for routing to a line-in or direct box?

Any advice is appreciated.

A regular 1/4 inch should be fine, but if youre planning on doing live sessionns, I would recommend getting a cheap mixer as well so you can mix the vocals to your liking when going into the sp

Hey thanks for the input. I have a 2 channel Behringer I'll probably be able to use. Thanks for your suggestion!
