Rightmark Audio Analyzer



We used Rightmark Audio Analyzer together with a loop-back cable to analyze the quality of the on-board audio solution. It is the first motherboard we tested so far to receive RMMA's "Very Good" rating.

Please note that even though the sound chip supports 5.1 Audio, ECS has not included the required connectors on the back output jacks.

Summary

Frequency response (from 40 Hz to 15 kHz), dB:+0.25, -0.32Good
Noise level, dB (A):-86.4Good
Dynamic range, dB (A):86.2Good
THD, %:0.0025Excellent
IMD, %:0.019Very good
Stereo crosstalk, dB:-85.4Excellent
IMD at 10 kHz, %:0.105Average

General performance: Very Good

I must say I was genuinely suprised by the high audio quality the ECS G31T-M offers.
