STEP 6 – Clocking
So far, the system has been set up to lock to the clock generated by the source, or in Master Mode for
asynchronous Network and USB interfaces. This is the simplest arrangement, but it does not give the
very best sonic performance due to clock jitter.

Using the Rossini Clock

The performance can be improved further by adding a Rossini Master Clock to the system.

• Play some music.
The Rossini Clock provides the DAC with 44.1kHz and 48kHz word clock simultaneously, ensuring it
can stay locked to any valid sample rate.
• If you want to lock sources connected to the AES or SPDIF inputs to word clock, we suggest that
you consider using the Vivaldi Master Clock to synchronise the system. It has many more outputs
than the Rossini Clock.
Please note if you lock one of the DAC's AES or SPDIF inputs to a Master Clock, the
source equipment (e.g. a CD player) MUST be locked to the same Master Clock,
!
otherwise you will experience periodic clicks, dropouts, noises or distortion on the output.
For more information, please see the manual for the Vivaldi Master Clock.
