Chapter 5: Software support
• Dolby
®
Surround Encoding - enables audio to be encoded for
playback on home theater receivers (using analog stereo outputs only)
• Dolby
®
Digital Encoding - enables audio to be encoded for playback
on 5.1 home theater receivers (using digital SPDIF output only)
Here are some of the features on the Speaker Setup:
This optional S/PDIF audio module allows digital instead of analog sound
input and output.
For S/PDIF out function, you may use either the module or the S/PDIF
connector at the back panel, but not both.
• Create Center Channel - Generates a center channel for audio
content that does not have it natively (like MP3s, WMAS, etc.)
• Create Channel 3D Pan - Allows game sounds to be panned through
the center speaker when they pass between the left and right speakers
(only works for DirectSound3D games)
• Create LFE Channel - Generates a subwoofer signal for speaker
systems that require it (like Dolby Digital receivers or home theaters
with discreet subwoofer inputs)
• Rear Speaker Phase Shift - Adjusts the output of the rear speakers so
that sounds don’t ‘cancel out’ and remove the bass channel or cause a
‘tinny’ sound (primarily older 4 channel PC speaker systems)
• LFE Crossover Frequency - Adjusts the amount of bass signal
removed from the main speakers and sent specifically to the
subwoofer output (increment in hertz).
