Audio
by John Anthony
- Speakers and headphones are the primary audio output
devices for a PC.
- Some monitors have speakers built into their sides.
Other speakers are free standing.
- Passive speakers plug into and are powered directly
from the output signal provided by the 'speaker out' port
on the sound card.
- Active speakers amplify the sound signal from the sound card
using battery or rectified AC house power.
