Sample Rate Conversion<br />
These settings allow you to adjust the selected sample rate by a fixed ratio.<br />
The ratio 1.000 has no effect on the selected sample rate.<br />
The ratios 1.001and 0.999 would be used to <strong>com</strong>pensate for 29.97 to 30F<br />
timecode transfers.<br />
• Press the Setup Button<br />
• Use the Rotary Wheel to select the Clocks menu.<br />
• Press the Parameter Down button and use the Rotary Wheel to select<br />
the .Modify heading.<br />
• Use the Value Up and Value Down Buttons to select a modifier.<br />
• Press the Enter button to confirm the selection.<br />
Note that with no sample rate conversion, this setting modifies the playback<br />
rate and therefore the pitch of playback audio. Modified rates are not<br />
available at present for PCM rates of 176.4kHz or 192kHz, or in DSD mode<br />
Each audio channel is fitted with a sample rate converter that can change the sample rate of the<br />
output audio. For I/O Cards fitted with sample rate converters, if the sample rate converter is in circuit,<br />
you can adjust the playback clock rate and the I/O clock rate independently. The sample rate menu<br />
heading (.SmplRte) in the Clocks menu sets the I/O clock rate and the playback clock menu<br />
(.PlayClk ) determines the playback speed of the unit.<br />
