Topic: rme hdsp 9632 connection to krk vxt4

hi guys

i have just bought a new digital audio workstation in which i included krk vxt4 as monitors and rme hdsp9632 as audio card

now, i am almost a beginner, so i am going mad in understanding how exactly i have to connect the 9632 to the monitors; in particular, i would like to know :

1) is it better to have balanced or unbalanced cables? and why?

2) the basic output of hdsp 9632 are rca? are they unbalanced? how can i connect a simple "mono" jack from the 9632 to each of the vxt4?

3) i obviously (?) need another cable to connect the 9632 to the vxt4, bacause they are all "females" plugs?

please help me

bye and thank you
