RMAA Testing (2)

THD + Noise (at -3 dB FS)This measurement indicates how much Total Harmonic Distortion and Noise is present in the cards output signal. Harmonic distortion presents itself as multiple odd and/or even harmonic overtones in the original signal. The lower the measurement the better and the Forte 7.1 produced excellent THD+N measurements across the test set.

Intermodulation Distortion
This graph shows the measurement of IMD. This type of distortion results from multiple signals being mixed together and producing distortion in the form of overtones that are not harmonically linked to any of the base signals. Lower measurements are definitely preferred for any type of distortion measurements. The lower the measurement the better and the Forte 7.1 produced excellent results through our test sets.

Stereo Crosstalk
This graph is a measurement of the bleed-through effect from one stereo channel to the other. The lower the measured crosstalk values are the less bleed through. On our measured graph, at 24bit 96,196 the crosstalk cannot be measured in the lower frequencies although in the higher range they elevate up a little. The Auzentech Forte 7.1 produced excellent measurements for stereo crosstalk across our test set.
