These settings are usually "set and forget".

Sync Mode

This page sets the clocking for the digital input that is currently selected. The DAC
remembers the
Audio – The DAC extracts the clock from the data stream connected to the selected digital
input and locks to it. Use this setting for sources that do not have a suitable Word Clock
input. This arrangement does NOT give the best jitter performance or the best sound
quality. The
Master – This is the normal mode for the asynchronous
Master clock is not available. The DAC uses its own internal clock to control the internal
DAC and regulate delivery of data packets. In this situation, the DAC is acting as the
source device.
When using the AES or SPDIF inputs in Master Mode, the DAC again uses its internal
clock to control the DAC and outputs a clock signal at the

computer audio system, where the data rate may keep changing. Connect the
Clock In1 input to a Clock output set to 44.1 or 88.2 or 176.4kHz and connect the
Clock In2 input to a Clock output set to 48, 96 or 192kHz. When the sample rate changes,
the DAC will automatically select a Word Clock frequency that is synchronous with the
data. The selected word clock input appears on the main display.

If the DAC cannot find a word clock that is synchronous with the data on the selected AES
or SPDIF input, it will default to
