Line Out 1: Line Out or SPDIF (The SPDIF output is

capable of providing digital audio to external speakers

or compressed AC3 data to an external Dolby digital

decoder). In general, Line Out 1 is normally Line Out,

when it output digital signal, it will be change to SPDIF

Out automatically (see page 47 for more information).

Line In: In general, Line In is normally Line In. When

you select “Four Speaker” in Creative application

(see page 45 for more information), Line In will be

change to Line Out 2, then you can plug 2 pairs stereo

speaker into Line Out 1 and Line In simultaneously.
