This has bothered me for quite a while :ugh:... I cannot work out what the 'line-out' port is for on computers/laptops. The port is the same size as the one for headphones and is usually right next to it. Can anyone enlighten me?

Thanks, isi3000 :)

Quite simply, 'line out' provides a matching input for, say, hi-fi systems which have a line-in socket. Loudspeakers expect an impedence of 4 - 8 ohms; line-in terminals 600 ohms as I remember. If you have a mismatch you might well have a distorted input - apart from the possibility of blowing your input circuits if you put a lot of power into an amp which isn't expecting it.

Right ok thanks jimtherev :}.
