Reply to traktor audio 6

hi im new on this community and dont know if i can get any info on this subject.
i have been using traktor pro with a reloop digital jockey 2 interface edition which i have grown out off at this stage. i am now considering purchasing an traktor audio 6 ,external mixer and 2 kontrol x1s and upgrading to pro 2.im just wondering if any of you guys know if i can route 4 channels or 2 channels + 2 sample decks through the audio 6 to the external mixer and if the led indicators will show levels etc.thanks.
