STEP 4 – Choosing a Sync Mode
So far, the system has been set up to lock to the clock generated by the source. If you are using the
1394 or SDIF interfaces, the DAC will lock to a word clock generated by the source. This is the
simplest arrangement, but it does not give the best sonic performance due to clock jitter.
Using the DAC in Master Mode
If your CD transport (or other source equipment sampling at 44.1kS/s) has a word clock input, you can
reduce the jitter in your system by using the DAC in Master mode and slaving the source to it. If not,
you can miss out this section.

clock and the DAC is receiving data at 44.1, 88.2 or 176.4kS/s or DSD. If the system is
not set up correctly and fails to lock, you will hear clicks / noises from the speakers and
the signal may be distorted.
