Weak audio from deck A

[b dub]

I have tried several things to correct this problem including changing usb cables and trying different outs on the Audio 8. Deck A is the only one that comes out at half volume while all the other decks sound fine. There are no effects active and it is all configured correctly. I have Mac osx 10.5.8 and Traktor Pro 1.2.4. Any ideas of things i could try are appreciated.

internal? external? timecode?

have you double checked the gain?

would i be correct in assuming you've tried all decks with the same track to elminate if it's the deck or a specific track?

External mix, no time code, same track, gains are equal. Sounds full on all other decks except A. This one is over my head.
