The jack on the mixamp is a headset jack (mic and headphone in one plug). the other jack is for the xbox controller only. The Y splitter splits the headset jack into a mic jack and headphone jack so you can use a PC headset that has a mic and headphone jack with the mixamp. Additionally you can't use a stereo Y splitter with the mixamp and expect it to split the mic and headphone audio.
