STEP 8 – Setting the Sync Mode for Computer Audio sources

Using the DAC in Universal Master Mode

You can improve the quality of playback from the Upsampler's USB and Network interfaces by locking
the Upsampler to the DAC's clock. This does not work well in standard Master Mode as the sample
rate may change between 44.1k-related rates and 48k-related rates. To solve this problem, the Vivaldi
DAC with software v1.10 (or later) has a Universal Master Mode which produces a 38.4kHz word clock
from which either base rate can be derived easily. Vivaldi Upsampler v1.10 (or later) can lock to this
frequency.
