Reply to some questions about HDJ2000 and ADAM A8X

hello,

just got the pair of A8X and HDJ2000.

i would like to know if there's any recommendations for the burn in on Adam A8X and for the PIONEER HDJ2000.

what do you recommend?

another thing, can you explain me how to use the high/low shelf properly on adam a8x.
i know it depends on my room space, but is there any manual about it?

does the XLR connection cable's better than the regular jack ?
the quality is better?

i'm kinda newbie in this aspect and, i hope some of you can help me.


best regards.
