ASUS Strix Raid DLX 7.1 PCI Express Sound Card

The ASUS Strix Raid DLX 7.1 is a PCIe sound card built for high-fidelity audio. It converts digital signals into analogue 7.1-channel surround sound, supporting 24-bit/192kHz high-resolution playback. With a signal-to-noise ratio of 117 dB and 0.0009% total harmonic distortion at the line-out, it provides a clean audio signal. The card features five analogue outputs and a dedicated subwoofer port for various speaker configurations, as well as an S/PDIF output for digital connections to external equipment.

The card uses a C-Media 6632AX chipset and a dedicated digital-to-analogue converter. Its integrated headphone amplifier supports studio headphones with an impedance of up to 600 Ω. Installation requires a standard PCIe slot. The card is compatible with Windows 7, 8, and 8.1. A separate desktop control box allows for physical volume adjustments, while an illuminated owl-eye motif on the shroud indicates system status. Minimum system requirements include 256 MB of RAM and 60 MB of storage for driver installation.
