Page 10 - Onboard Sound Frequency Analysis
ASUS promises solid audio performance with the ROG Strix B660-I Gaming WiFi motherboard. This mITX gaming motherboard uses a ROG SupremeFX 7.1-Channel High Definition Audio 32-Bit/192 kHz audio codec. Further sound quality optimization is made with audio-grade capacitors and audio shielding. To see how it performs, we fired up RightMark Audio Analyzer for the answer, and here is the full report.
