Audio 4DJ compatible with TP2.5?

Ok, so im moved away from traktor 2 years ago prefering to use cdj's. Now 2.5 and remix decks has got me back wanting to play out with traktor again.
silly question.... will my audio4 be compatible for using T2.5 or will I need to upgrade to audio 6.

Yes, it's compatible. Same goes to the Audio 8.

sweet

It is comparable. It's what I have.

Same here. Audio 4 DJ and TSP2.5.

Works perfectly for me on Mac.
