World-exclusive ROG Command technology was specifically developed by the Xonar team to bring effective noise cancelation to a gaming soundcard set. Intelligent sound detection algorithms and array microphones (two on the dedicated control box) enable up to 50% ambient noise reduction, effectively turning loud locations such as LAN parties into something as quiet as a library.   ow it works? - With external microphone A smart algorithm analyzes sound detected by both the external microphone and one of the micro-mics on the control box to cancel out environmental noise.   - Without external microphone Array microphones on the control box form a virtual 30ﾟcone of precise voice capture.     *Control box intelligently detects plugged-in headsets when engaging ROG Command features     Embrace Exceptional Sound Quality for the Win     118dB Clarity SNR Up to 4X audio clarity compared with the SNR ratios of competing gaming audio cards.   Hyper Grounding technology Noise-blocking multi-layer PCB designed with decades of ASUS professional layout experience.   Digital to Analog Converter (DAC) The PCM1796 digital-to-analog converter on ROG Xonar Phoebus delivers clear and crisp 118dB SNR high fidelity audio. The new soundcard therefore outperforms competing gaming audio products by a factor of four, and onboard audio by an impressive 32 times. It also excels in total harmonic distortion (THD) performance, with a miniscule 0.00039% of sound output experiencing distortion.   EMI Shielding Stylish and efficient EMI shield blocks electromagnetic interference to help provide cleaner audio                  Headphone Amplifier Since many gamers choose to refrain from disturbing others while insisting on the best sound quality, ROG and Xonar teams integrated the top-flight TPA6120A2 headphone amplifier on ROG Xonar Phoebus, driving up to 600 ohm impedance for genuinely impactful headphone output.       3 Headphone Gain Settings Three different gain settings cater to various headphone impedance levels, with aesthetic lighting that changes accordingly: blue for ‹32 ohms and red for the two settings over 32 ohms.     * SNR (Signal-to-Noise Ratio) unit is dB. SNR= 10log (Psignal/Pnoise); p represents power ** Compared with the SNR ratio (109dB) of average competing gaming audio cards   Control Box within Easy Reach   Hassle-Free Headset Connections Clad in the trademark ROG red and black color scheme, the ROG Xonar Phoebus control box offers gamers improved response and convenience. Connected to the card via the back I/O, the control box can be placed on the desk so it remains within easy reach. The control box further offers microphone and headphone connectors, making it possible to use even short-wired headsets with ease, as it brings the connectors closer to gamers.   Instant Volume Tuning Gamers can easily adjust volume and one-click mute quickly without bringing up game or operating system menus, or having to hunt around for display remote controls.     Illuminated Gold-Plated Jacks Gold-plated jacks ensure greater durability. To help with gaming in the dark, the control box headphone-out lights up green, while the microphone-in glows red!   New Xonar Audio Center   Effortless adjustment with New Xonar Audio Center The latest Xonar audio center brings great sound combined with the spirit of ROG to provide gamers impactful and precise audio control delivered in style.
