Page 11 - Onboard Sound Frequency Analysis
Gigabyte has a great record of having very good performing integrated audio on their motherboards, and the GA-Z97X-UD3H-BK is advertised to be no exception. It comes with a rear headphone amplifier that can drive up to 800 ohm loads, and comes with a dedicated audio zone electrically separated from the rest of the components to reduce noise. This mainstream performance model uses Realtek's ALC1150 audio codec. To see how it performs, we fired up RightMark Audio Analyzer for the answer, and here is the full report.
