Reply to S4 Booth Outputs

So me as many others have a need for booth outs and being that this is a huge issue I need to get this taken care of fast

This is what I was advised to do get a mixer that was recommended by a sweetwater rep to use a Mackie 802-vzlz3 at times I do need additional mike outs and can use the additional channels they do have a smaller one but this is perfect

Here is the Mackie http://www.sweetwater.com/store/detail/802VLZ3/

He said they way I should hook this up is with a Y cable out from the S4's headphone jack and not plug in the S4 direct to the mixer...

Does this make sense to anyone
