Sample Rates and Per<strong>for</strong>mance<br />
Input sample rate always shows the detected sample rate coming in from your<br />
optical cable. If this value varies continuously, please check if you configured the<br />
input correctly (Did you choose ADAT as input and falsely connect it to an S/PDIF<br />
device or vice versa?).<br />
What will be displayed as Output sample rate depends on the settings in the General<br />
page. If you chose LAGOON as clock source, Output sample rate should always<br />
match the frequency you set in the LAGOON Tools General page. If you chose<br />
Optical In, Output sample rate should be the same as the one you are feeding in into<br />
the optical input of your LAGOON card. If you chose ADAT Sync In, the sample rate<br />
at the output will match the word clock frequency from the ADAT Sync In interface.<br />
DSP load shows the percentage of the DSP power which is currently required by the<br />
system. This depends on which <strong>for</strong>mat (ADAT or S/PDIF) you are using and if many<br />
repeated PCI transfers have to be carried out.<br />
The percentage of PCI-repeated transfers indicates if the PCI bus is behaving as it<br />
should. In most systems it should only display a few percent. If you see a large<br />
number of PCI-repeated transfers (up to 10 percent and above), then perhaps you<br />
have an older mainboard in your PC that is not suitable <strong>for</strong> multimedia demands.<br />
