Noise Level And Interference

DMX 6Fire 24/96

Audigy Platinum

The second test dealt with the level of noise and interference, especially measuring the background noise of the card and indicating the sensitivity of the card to various forms of interference that arise near computers: power supplies, transformers or monitor screens. Here again the DMX 6Fire 24/96 beats the Audigy Platinum, with respective results of 89.7 dB versus 85 dB (A-Weighted).

Dynamic Range

In addition to the preceding test, the dynamic range test estimates the level of noise generated in the presence of a sound signal, in this case a sine wave (1KHz at -60dB) at the card input. This test gives a true idea of the card's dynamics during a recording. Yet again the DMX 6Fire 24/96 wins, with a slight lead at +82.8 dB against +81.9 dB.
