The Auzen X-FI™ Prelude 7.1 soundcard marks the first time Creative has
permitted a third-party soundcard vendor to use the Creative X-FI™ chipset in
its own soundcard design. The Auzen X-Fi Prelude 7.1 soundcard will fully
support EAX 5.0 and have the same expandability as the Auzen X-Meridian™ 7.1.
Additional features such as Dolby® Digital Live, DTS® Interactive, and DTS NeoPC™
will be available soon via driver updates.
EAX®
Take advantage of the latest EAX® sound card technology of Creative Labs. Enjoy
a 3D soundscape during gameplay. Bullets whiz past your head. Explosions shake
the room. Take your games to the next level with EAX® ADVANCED HD™ sound
effects, available in Vista via OpenAL.
Why X-Fi® ?
* The speed you need: Powerful audio processing engine boosts real game
performance by more than 15% over ordinary motherboard audio.
* Hear your enemies before they find you: Slip on your headphones or put your
multichannel speakers to work for you with positional audio that's so accurate
you can locate enemies by sound.
* Revitalize compressed audio: X-Fi Crystalizer technology restores the detail
and vibrance to your compressed music and movies. In games, X-Fi Crystalizer
makes gunshots sound crisp and sharp and explosions really boom for the most
intense gaming experience yet. All the highs and lows are intelligently enhanced
so you'll hear everything in crystal clarity.
* Turn stereo music and movies into surround sound: X-Fi CMSS-3D technology
expands your stereo MP3s and digital movies into surround sound over
multichannel speakers, stereo speakers or even headphones. Voices are centered
in front of you and ambient sounds are moved all around you.
* Enjoy clearer voice chat: Talk it up and hear the difference X-Fi makes. Every
voice comes through loud and clear.

Hardware
Better Circuit Board. Better Audio.™
The Auzen X-Fi Prelude is a one-of-a-kind circuit board designed by Auzentech's
engineers, leaders in the fields of analog and digital audio. Assembled with
superior components, the board includes Auzentech-only innovations such as user-upgradable
Operational Amplifiers, combo-ports that support both coaxial and optical
connectors, and more.

National LM4562NA High Performance Audio OPAMP
The LM4562 from the NATIONAL combines extremely low voltage noise density
(2.7nV/ √ ^Hz) with vanishingly low THD+N (0.00003%) to satisfy demanding
audiophiles.
TI OPA2134 SoundPlus™ High Performance Audio OPAMP
The OPA134 series are ultra-low distortion, low noise operational amplifiers
fully specified for audio applications. A true FET input stage was incorporated
to provide superior sound quality and speed for exceptional audio performance.
Swappable OPAMP Socket (Front L/R only)
OPAMP IC can be easily replaced with another one. The swappable dual DIP type
Operational Amplifier(OPAMP) provides convenient do-it-yourself upgrade for
ultimate analog sound quality and color.
Optical / Coaxial COMBO Port
The SPDIF Output port has 25mbps bandwidth and supports DTS-
HD/DolbyTrue HD. It is possible to shift between Optical and Coaxial in this
port.
AKM AK4396VF DAC
The AK4396 is a high performance stereo DAC for 24bit 120dB stereo, 96kHz
sampling rate, DSD Input, ultra-low out-of-band noise, 180mW, digital attenuator
manufactured by Asahi Kasei Micro systems.
AKM AK5394AVS ADC
The AK5394A is a 24bit, 96kHz sampling 2ch A/D Converter for professional
digital audio systems. The modulator uses the new advanced multi-bit
architecture and achieves 123dB dynamic range and wide bandwidth with superior
distortion characteristics.
Solid Condenser for maximum durability & stability
The solid capacitor has been adopted to provide higher durability and stability
than usual condensers, and to stabilize the electric power source.
Additional Features Coming Soon
The following features will be made available via driver updates.See the
schedule for driver availability. The X-Fi Prelude 7.1 soundcard is
hardware-ready for these features.
Dolby® Digital Live
Enjoy audio from your PC or game console through your home theater with Dolby®
Digital Live. A real-time encoding technology, Dolby Digital Live converts any
audio signal into a Dolby Digital bitstream for transport and playback through a
home theater system. With it, your PC or game console can be hooked up to your
Dolby Digital-equipped audio/video receiver or digital speaker system via a
single digital connection, eliminating the confusion of multiple cables and
ensuring the integrity of the audio signal. Note: The following Dolby®
technologies will not be supported on the X-Fi Prelude 7.1 due to feature
overlap: Dolby® Pro Logic® IIX, Dolby® Virtual Speaker, and Dolby® Headphone.
Available in future drivers : Schedule
DTS® Interactive
DTS® Interactive provides a single cable connection, either coaxial or optical,
to your DTS-enabled surround sound system. An Auzentech sound card that supports
DTS Interactive will re-encode your stereo or multi-channel audio sources into a
DTS audio signal and send it to any DTS enabled system. The receiving system
could be powered PC multi-channel speakers, an Audio Visual surround receiver,
or any other surround sound decoder. The installation process is simple and
avoids analog cable clutter. Source files may have as few as two- and as many as
5.1-channels before being up-sampled.
Available in future drivers : Schedule
DTS NEO:PC™
DTS NEO:PC™ is an up-mix component of DTS Connect® that allows multi-channel
output from two-channel sources. It can be combined with DTS Interactive™ to
send the signal to your audio visual receiver.
Available in future drivers : Schedule
