1.3 3D Surround Sound
Our 3D surround function takes any ordinary stereo signal as input and
produces an output signal with dramatically widened stereo imaging and
enhanced realism. And requires no extra speakers or special encoding of
input signals.
You can turn 3D sound on or off by program CMMIX.COM at DOS.
At Windows you also can turn it on or off by Audio Rack mixer. And
you can run Windows applications DEMO3D to test 3D surround
sound functions.
1.4 What is SPDIF IN/OUT ?
SPDIF is a digital audio IN/OUT standard. It support a non-distortion
stereo 44.1K 16bit digital audio transmission. You can get digital audio
through SPDIF IN from CD-Audio digital output or the other digital
audio output. You also can output digital audio through SPDIF OUT to
those equipment’s that accepted SPDIF IN format.
The AudioPlus 6400 3D SPDIF IN function is design for non-distor-
tion digital recording from digital audio output of CD-ROM (or other
equipments), not for playing from these equipments. Therefore, if
you want to record from your CD-ROM digital audio output through
AudioPlus 6400 3D SPDIF IN, please connect CD-ROM analog and
digital audio cable to sound card. Make sure that volume of CD(analog
audio) in mixer is ON and volume of Dig-CD(digital audio) is OFF.
Then you can playing from analog audio and recording from digital
audio for the best effect. If you turn on the volume of Dig-CD(digital
audio) in mixer, due to some CD-ROM drive design,there is noise
input during CD-ROM door open or close. Besides, SPDIF can not
adjust volume. So we recommended you to follow the steps that de-
scribe above.
