"As you can see, all the connectors you are likely to need are on the one card. Most convenient are three dedicated line outputs for the full 5.1 speaker complement, and. unlike some cards these outputs are not shared - you don't have to choose between Digital out and the third speaker pair. Another feature you won't find on many cards is a headphone amplifier. By changing a jumper on the card you can set the line in output to be a headphone out - this includes enough amplification to drive even 300 ohm headphones using a simple pair of LM386 op-amps. "
