Hello everybody.
I got a doubt. If I want to connect my Laptop PC to the multichannel
amplifier (Denon) and I haven't the line out connector on the PC, is it
possible to connect it using the headphones output without the risk of
damaging the amplifier?

Yes.

The headphone output voltage may be a little higher than line level though
so don't turn it up full until you've got used to the setup and checked it
out.
