ROG Command technology
Precise positioning and lifelike immersion

Get the drop on opponents with improved audio positioning and bask in game music with crystal-clear 118dB SNR sound. All done by the creators of Xonar Xense (2011 CES Innovations Award winner) and Xonar Essence One (2012 CES Innovations Award winner). The commitment of the Xonar team delivers leading-performance gaming products, merged with the excitement of a unique, stylish and gamer-focused design. ROG Xonar Phoebus, named after the Greek god of the sun and music, comes with exclusive ROG Command technology, Hyper Grounding technology, EMI-shielding and top notch components, combined with the latest Dolby® surround enhancement to ensure you hear exactly what game designers want you to hear.

ROG Command Technology Boosts In-game Voice

Clearer communications with up to 50%
environmental noise cancelation

Beyond excellent sound quality, ROG Xonar Phoebus gives you clean and seamless communications for a totally immersive experience. 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.

Excellent sound quality
How it works?

With external microphone - 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 - 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 ‹64 ohms and red for the two settings over 64 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.

Hassle-Free Headset Connections
