2.  Set the Output Resolution:  Choose the Output Resolution to be either 16 bit or 20 bit.

3.  Set the Recording Resolution:  Select the Dithering Tab and set the recording resolution to 16 bit or 24 bit.  Selecting 32 bit will still open a 24 bit stream via the USBPre.

4.  Set the System performance:  Choose Highspeed, Fast, Normal, or Relaxed.  The latency times associated with each are displayed below.

5.  Set the Dithering check box:  The use of dithering will improve the conversion to a lower bit depth on both the output and the input. Enable the "use dithering" check box in two situations. 1) The ASIO recording resolution is set higher than the application recording resolution. 2) The application output resolution is higher than the ASIO output resolution.
