Sample Rate
The sample rate determines the number of audio samples per second that the Digital-to-Analog
Converters (DAC) and S/PDIF digital interface will output. The Essence STX II card can support
sample rates up to 19KHz (44.1K, 48K, 96K, 19KHz). Usually audio CDs and MP files are 44.1KHz;
DVD-Video uses 48KHz; DVD-Audio or other HD media may contain 96KHz or 19KHz high-
definition audio content. Select the corresponding sample rate for your playback sources to get the
best audio fidelity. Even if your setting differs from the audio source’s sample rate, the Essence STX II
engine will do super high fidelity sample-rate-conversion with a double floating-point filter, which
can reduce total harmonic distortion (THD+N) by -140dB.
Sample Rate.
Select the sample rate that corresponds to (or exceeds that of) your playback
sources, for optimal audio fidelity. Essence STX II card supports sample rates up to 192KHz

• Audio CD, MP, WMA, Wave files are 44.1KHz;
• The audio of DVD-Video is 48KHz;
