Audio

SupremeFX

Exceptional RMAA Performance - Built-in ROG SupremeFX audio technology ensures pristine audio for ROG Strix B550-A Gaming. Along with providing a flat frequency response for a neutral, detailed sound signature, it offers two front-panel outputs driven by op-amps that deliver high-quality audio to gaming headsets.

Audio cover

Effective shielding against electromagnetic interference preserves the integrity of audio signals for the best sound quality.

Audio-line shielding

Blocks electromagnetic interference from the motherboard or add-ons to provide cleaner audio.

Dual OP amplifiers

With two op-amps onboard, you can pump exceptional audio to your favourite cans, with 32-600Ω-headphone impedance for incredible flexibility.

Premium Nichicon audio capacitors

Fine-quality Japanese-made components produce a warmer, natural sound with exceptional clarity and fidelity.

Two-way AI Noise Cancelation

This utility leverages a massive deep-learning database to reduce background noise from the microphone and incoming audio while preserving vocals simultaneously. Distracting keyboard clatter, mouse clicks and other ambient noises are intelligently neutralised so you can hear and be heard with crystal clarity while gaming or in calls.

*A splitter cable is necessary when using a 3.5 mm headset.

*Actual performance varies by configuration

*Testing configuration: CPU: 11th Gen Intel Core Processor; Motherboard: ROG MAXIMUS XIII HERO; Graphics card: NVIDIA RTX 3070; DRAM: G.SKILL F4-3200C16Q-32GVK; Power: SUPER FLOWER 550W; HDD: ADATA SX910 SSD 128G; Cooling: Enermax T.B.APOLLISH; Game: CALL OF DUTY: MODERN WARFARE; Voice Communication App: Discord (In-app noise-cancelling effects disabled); Background noise: Keyboard typing, mouse-clicking, people talking, and music playing

Minimal Performance Impact

Sonic Studio III

Sonic Studio supports HRTF-based (head-related transfer function*) virtual surround for VR headsets, casting an immersive aural landscape that draws you deeper into the action. The intuitive Sonic Studio interface also offers a range of EQ options and one-click presets, allowing you to tailor acoustics to suit your headset's personal preferences or characteristics.

SONIC STUDIO LINK

The new Sonic Studio Link allows you to apply Sonic Studio effects on all playback devices. Press the Sonic Studio Link button to enjoy the impact on any connected device.

SONIC STUDIO VIRTUAL MIXER

Mix your voice and video game audio using this software specifically designed for streaming applications—a variety of settings and monitoring.

APP-SPECIFIC PROFILES

Apply customised audio settings to various applications so that each is perfectly tuned to the way you want to listen.

*A head-related transfer function is an audio algorithm derived from sound data recorded through a dummy head. Test tones are played from a spherical grid around the dummy head to obtain subtle changes in sounds that come from different directions. The results are combined into an algorithm that allows Sonic Studio's virtual surround to process audio that’s true to life.

DTS: Sound Unbound

ROG Strix B550 series motherboards are pre-loaded with the DTS Sound Unbound app that envelops you in audio as never before, conjuring whole new levels of immersion for incredible gaming and entertainment experiences. By leveraging Windows Sonic spatial technology, DTS Sound Unbound delivers audio in a virtual 3D space — putting you right in the middle of the soundscape, where you can sense the location and direction of every gunshot, footstep or other sounds in your virtual environment.

*DTS Sound Unbound requires in-game support. Check with developers for supported titles.

STEREO SOUND - Discrete left and right audio channels enable headphone or two-speaker setup.

SURROUND SOUND - Audio is split and served over multiple speaker channels – e.g., 5.1 or 7.1 – to create an enveloping experience on a single, logical plane.

SPATIAL SOUND - A virtual audio ‘sphere’ effect creates astonishing 360° immersion — with you at the centre, where sounds seem to travel in all directions.

All-round Performance

ROG Strix B550-A Gaming provides robust power delivery to fuel Ryzen’s cores, comprehensive cooling, and support for faster memory — so it has everything you need to load up your build with high-performance components for playing in the big leagues.

Power Design & Cooler by Design

Digital power control and an array of power stages ensure ROG Strix B550-A Gaming has the muscle to control the latest AMD CPUs. ROG Strix B550 series features the most comprehensive cooling options ever, configurable via Fan Xpert 4 or the UEFI BIOS.

CPU Fan Header & AIO Pump Fan Header

A dedicated pair of PWM/DC fan headers for CPU coolers. A dedicated PWM/DC header for self-contained water-cooling setups.

M.2 Heatsink

Keeps the M.2 SSD at the optimum operating temperature for consistent performance and reliability

Chassis - 4-pin PWM/DC Fan Header

All onboard headers support auto-detection of PWM or DC fans.

VRM Heatsink

MOS heatsink provides a large contact area for MOSFETs and chokes.

Thermal Pad

A high-quality thermal pad helps transfer heat from the inductor and phase array to the heatsink.

ASUS OptiMem II

To provide AMD's latest CPUs unfettered access to memory bandwidth, motherboard trace routing has been reimagined with the ROG Strix B550-A Gaming. Integrated OptiMem II technology carefully maps memory signal pathways across PCB layers to reduce vias, and it also adds shielding zones that significantly reduce crosstalk. A highly customised Daisy Chain layout delivers time-aligned signalling to enhance further overclocking headroom for fully stacked memory configurations.
