A full Vivaldi system
The Vivaldi’s clocking system has been designed to be very comprehensive to cope with multiple
sample rates with a mixture of clocked and un-clocked sources. This applies particularly to streaming
computer audio files with different sample rates, or using an Upsampler with a variety of output sample
rates.

The system shown above makes excellent use of the Vivaldi’s facilities. The Upsampler can be
sourced from the Transport, a PC, a NAS drive, an iPod/Phone/Pad or a USB flash drive. The multiple
clock connections (shown in green) ensure that the DAC and Upsampler can always access a suitable
clock, despite changing file sample rates and changing Upsampler output rates.
The Vivaldi Master Clock has 2 Groups of outputs, each of which can be set to any of 6 standard clock
frequencies. The DAC and Upsampler have 3 and 2 Word Clock inputs respectively, to ensure they
can have access to a suitable clock despite changing sample rates in the system.
