Product Overview

Enjoy Stunningly Detailed Audio with this Plug-and-Play USB Sound Card

Xonar U7 MKII is designed to provide the best audio experiences for PC gaming and media streaming. It delivers stunningly clear and impactful sound when listening with headphones or speakers that far surpasses onboard PC audio hardware. With convenient USB connectivity, Xonar U7 MKII gives you instantly upgraded sound quality without the need to open your PC case to install an internal sound card. Its USB design also eliminates the need for a separate power supply, so just connect one cable and start listening.

Powerful Sound from a Compact and Portable Device

Xonar U7 MKII engineering overcomes the space and power supply limitations of other external USB-based audio devices to offer precise and immersive 7.1-channel surround. Sound processing uses 192kHz/24-bit fidelity for true high definition output, maintaining consistent quality across all surround channels.

114dB Signal-to-Noise Ratio (SNR)

Up to 16X audio clarity compared with the SNR ratios of average onboard audio.

Hyper Grounding Technology

Exclusive ASUS Hyper Grounding PCB fabrication ensures strong signal insulation to reduce distortion and interference, also known as component crosstalk.

Digital to Analog Converter (DAC)

High quality Cirrus Logic® CS4398 DAC (digital-to-analog converter) brings clarity with excellent signal-to-noise ratio (SNR) and low total harmonic distortion (THD)

Integrated Headphone Amplifier Pumps Up Every Sound Detail

Since many gamers choose to refrain from disturbing others while insisting on the best sound quality, Xonar teams integrate a headphone amplifier on Xonar U7 to boost immersive headphone output.

Dedicated Headphone and Mic Volume Controls

Dedicated headphone and microphone volume enable instant audio level adjustments without the need to pause your game or navigate software menus, ensuring uninterrupted gaming and media streaming experiences.

Fast and Easy Switching Between Headphone and Speaker Output

The headphone volume control knob doubles as a clickable output selector for instant, convenient switching between listening with headphones and speakers.

Plug-and-Play USB Convenience

With its USB design, Xonar U7 MKII dramatically upgrades your PC's audio performance simply by plugging it in. It draws power directly from the USB port, eliminating the need for a separate power adapter. Its compact design fits almost anywhere and is easily portable, so you can bring it with your laptop and enjoy great-sound audio on the go.

Take Full Audio Control with Sonic Studio

Xonar U7 MKII features the latest Sonic Studio software suite for full control over every sound technology, from equalisation (EQ) to 7.1-speaker level-balancing. Sonic Studio has a single navigation page that puts everything in front of you, with an intuitive point-and-click interface that allows you to pre-set audio profiles to suit different audio requirements.

Gain the Gaming Edge with Sonic Radar Pro

Fire up your favourite game and Sonic Radar Pro displays a ‘radar' HUD (heads-up display) that pinpoints in-game actions relative to your position, so you'll know exactly where you are on the battlefield and what's happening around you!
