SpectraLAB Tests

We used SpectraLAB version 4.32.17 to test the Revolution 7.1 card according to the methodology explained in our previous reviews. The results refer to the LineOut 1 – LineIn link.


44,100Hz/16bit, 1kHz tone signal


Determining IMD at 44,100Hz/16bit


48,000Hz/16bit, 1kHz tone signal


Determining IMD at 48,000Hz/16bit

The spectrograms testify that Revolution 7.1 is a really classy high-quality product, thanks to its excellent signal converters in the first place. Overall noise level lies behind the –110dB mark and the results might be higher if it were not for certain minor harmonics spikes. Note that when the amplitude peak of the test signal equaled 0dB, there was no overshoot.

For a better comparison of the results I also provided the numbers for Audigy2 and Aureon. Note that Revolution 7.1 looks just perfect against these two competitors.
