Introduction
Introducing Your
“Digital Media Platform”

Thank you for purchasing MEGA651 PC, the Best of Computing & Home
Entertainment. Based on the design idea of consumer product, the MEGA651 is
not just a PC anymore. The equipped “All-in-One” features position MEGA651
as a “Digital Media Platform”.
From the recent years, the ownership and usage of desktop and notebook
PCs across W.W households has turned computers into a commodity item. While
Microsoft strongly promotes the “Media Center” platform concept “Windows XP
Media Center Edition” on HP “Free Style”, Intel is also exploring their “Digital-
Home” concept for the “Home-use” PC.
To meet the new concept of Home PC, the MEGA651 has been positioned
as a digital media platform to perform TV-recording (optional), home theater
(DVD+5.1 channels), digital audio playback (MP3, Audio CD), photo and video
stream data browsing/authoring/burning (optional with Media Center and bundled
applications). Meanwhile, it could also support high game performance (AGP
4X slot). The remote controller also allows you to use it like a Hi-Fi Stereo.
An innovative feature to implement all the Hi-Fi Stereo
into home-PC with a fancy equalizer LCM and control
panel in the front bezel.

SRS
MEGA651 is equipped with SRS audio enforce-
ment technology. SRS (Sound Retrieval System) was
the first generation of 3D sound, dramatically improv-
ing the quality of standard stereo. SRS is based on the
human hearing system and was designed to retrieve
the natural spatial cues and ambient information that
is present in audio but masked by traditional record-
ing and playback methods.
Whether the signal is mono or stereo, SRS ex-
pands the audio material to create a realistic three-
dimensional sound image. SRS has no sweet-spot and
fills the room with a sound experience much closer to
that of a live performance.
SRS is a trademark of SRS Labs, Inc. SRS tech-
nology is incorporated under license from SRS Labs,

ater function when PC button is pressed on.

music, viewing pictures and playing DVD..., etc.
