The Auzen X-Fi Bravura 7.1 is a sound card for playing Movies, Music, and Gaming. Enjoy breathtaking audio for music and movies with DTS™ Neo:PC and DTS™ Interactive (coming soon)[?]. And when it's time to unwind with your favorite PC Game, you won't be left behind with EAX 4.0. The Auzen X-Fi Bravura 7.1 is another in a long line of Auzentech sound cards with real technological innovations, such as optimal design for analog audio, I/O Mode Control, Independent Headphone Output Circuitry for professional headphones, and Auzentech's proprietary Pointing Ground Power Supply (for audio that is free of power supply noise).

Overview: The Auzen X-Fi Bravura 7.1 is designed for optimal audio output, both both digital and analog. The Creative X-Fi PCI Express Core Interface audio processor is on the back of the board while the analog circuitry is on the front, allowing for greater signal differentiation and better-performing analog circuit design.

PCI Express: PCI Express™ (PCIe) is a serial bus standard that provides a higher throughput than the older, parallel PCI bus standard. Unlike PCI Express™ sound cards built with PCI processors adapted for the PCIe slot, the X-Fi™ Bravura is built around Creative Labs' PCI Express™ processor. As a native-PCI Express™ sound card, the X-Fi™ Bravura can take full advantage of the higher-throughput of the PCIe bus.

I/O Mode Control: Auzen X-Fi Bravura 7.1 provides presets for Analog I/O to adapt to the environment of the user.

Multichannel Speaker output: The Auzen X-Fi Bravura 7.1 uses 114dB Digital to Analogue Converters (DAC) with high quality metalized capacitors for the filter circuitry. The Operational Amplifiers (OPAMPs) for all channels are upgradable.

Independent Headphone Output Circuitry: With a maximum sampling rate of 24/192 kHz output, the Auzen X-Fi Bravura 7.1 is suitable for professional headphones. The proprietary headphone amplifier uses an independent 120dB DAC, an upgradable OPAMP, and film capacitors for the DAC filter.

X-Balance Pointing Ground Supply™: Auzentech's proprietary Pointing Ground Design™ shares one point for the DAC, OPAMP, Power supply and to the output jack, stopping noise from interfering with the signal, outputting a signal with much less distortion. In the Auzen X-Fi Bravura 7.1, the design has been improved over previous models for even greater output filtering and driving capacity. The X-Balance Pointing Ground Supply™ uses Conductive Polymer Capacitors with ten times the ESR rating than normal condenser capacitors and a superior instant power supply capacity.
