Mapper

The Mapper
are now 3 Mapper options:
Map 1 is the new default mapper. It drives the Ring DAC™ core at either 5.644 or
6.14MHz.
Map 2 is the classic mapper design, used on all 1.xx versions of the Vivaldi DAC and
based on the design used by dCS for the last 20 years. It drives the Ring DAC™ at 2.822
or 3.07MHz.
Map 3 is an experimental design, which also runs at 5.644 or 6.14MHz.
Our listening tests concluded that
choice.

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 – The DAC uses its own stable clock while the

correct master mode operation, the source equipment MUST be locked to the DAC. This
is the recommended setting if you have a Vivaldi Transport, but not a Vivaldi Clock. The
