Performance: Audio Games »Rightmark Audio Analyzer
We used Rightmark Audio Analyzer together with a loop-back cable to analyze the quality of the on-board audio solution.
Summary
| Frequency response (from 40 Hz to 15 kHz), dB: | +0.28, -0.32 | Good |
| Noise level, dB (A): | -82.1 | Good |
| Dynamic range, dB (A): | 81.9 | Good |
| THD, %: | 0.0073 | Very good |
| IMD, %: | 0.053 | Good |
| Stereo crosstalk, dB: | -79.5 | Very good |
| IMD at 10 kHz, %: | 0.155 | Average |
General performance: Good
I am a bit dissapointed by that result. If a board claims to be a top notch gaming board, it has to offer better sound quality than "Good".
