Apple IPad with DJM 450 / 900 NXS2

Hello,

It will be great when some can give me this two answers 😀

1. DJM 900 NXS2

Is it possible to connect two ipads over lightning / USB with this clubmixer and mix from Channel A to B in high sound quality? I use DJAY 2 software from Algoriddim.

2. DJM 450

Is it possible to connect two or one ipads over lightning / USB with the mixer and mix from Channel A to B. 

if only one ipad, i can use the different Channels A and B to mix on the DJM 450

Thanks!

Marco
