Page 10 - Onboard Sound Frequency Analysis
ASUS promises solid audio performance with the ProArt B660-Creator D4 motherboard. It comes with a dedicated audio zone electrically separated from the rest of the components to reduce electrical noise. This mainstream performance model uses a Realtek 7.1 24-bit/192 kHz audio codec. Further sound quality optimization is made with a power pre-regulator, de-pop circuit, 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.
