You failed to mention if you are connecting your computer to your home speaker amplifier or connecting an iPod or something else.
It depends upon what type of amplifier you are using.
Most have a built-in preamplifier.
Some more elaborate home stereo systems have a separate preamplifier.
Plug it in and see if it works.

I would like to output MP3 music to my home speakers. Can I connect computer directly to my amplifier and play or will I need a pre-amp?
