This maybe the wrong three to put it on but if I do go with a beyerdynamic setup I was wondering if I would be able to do this. I have heard great things of the a40 mix amp and was wondering if I can set up the beyerdynamics to the mic/audio in/out and than connect via my ps4 through an optical cable that way I will have all the advantages of the mix amp with my headset. Thank you ahead of time
