Yep what Rippleish20 said! Just another reason I LOVE my MP3 & MP6!
You can route whatever signal and channels you want to to the 1/8" Stereo Out AND the 1/8" Headphone Outs
It's honestly kinda confusing at first, but after you play with it for awhile and start using it more often, you'll be able to do whatever you want to pretty quickly with it! I haven't recorded anything in 3 months, so I need a refresher course myself, especially since I just got a new MP3!!!
Remember, whatever is highlighted in BLUE, is what you have it set on!
