Thanks Geno,
was a bit confused on that, because I've read somewhere that both RS 232 & RJ-45 ports are intended for control systems (AMX, Crestron, etc.).
Probably I misunderstood that, though.
A friend of mine just got one and I'll be helping him out on the setup by tomorrow (its going to be his very 1st Denon AVR though).
Thanks again & have a nice weekend!
