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 192KHz (44.1K, 48K, 96K, 192KHz). Usually audio CDs and MP3 les are 44.1KHz;
DVD-Video uses 48KHz; DVD-Audio or other HD media may contain 96KHz or 192KHz high-
denition audio content. Select the corresponding sample rate for your playback sources to get the
best audio delity. Even if your setting diers from the audio source’s sample rate, the Essence STX II
engine will do super high delity sample-rate-conversion with a double oating-point lter, which
can reduce total harmonic distortion (THD+N) by -140dB.
