Alpha Theta 3000x & DJM-A9

Just received my pair of 3000X and A9, this is my 1st Pioneer DJ equipment which I've purchased. I'm old school (very old) who has always used my vinyl collection with SL1210's and A&H Xone mixers..

So this was quite a heavy cost investment.. but looking forwards to my digital journey with this kit.

Any tips and tricks (or abuse because you may think I've purchased stupidly) more than welcome, happy to hear thoughts good or bad.
