Hello Everyone, I couldn't quite figure out which forum to put this under, so I took a shot in the dark with this one. This issue seemed right up yall's ally as well. I'm looking to be able to feed a mixer into an Xbox Controller, and connect a set of speakers up to be able to listen as well. The headset connects to the controller using a 2.5mm jack, just like what is used on nearly every cell phone headset. I have attempted connecting the controller to the mixer using the line out and the master out, trying all wiring combinations on both, all to no avail. So now I am curious as to if perhaps the headset works is on a different audio level. I know I haven't blown the piece that connects to the controller because when I stick the old headset back in it, it works properly. If anyone is curious the purpose of this is to enable my friends and I to jam out over xbox live while someone else is playing Halo. Thanks again in advance for any ideas.
