If several digital devices are to be used simultaneously in a system, they not only have to oper-
ate with the same sample frequency but also be synchronous with each other. Therefore a Mas-
ter has to be defined within the digital system, sending the same clock signal to all the other
devices.
RME’s exclusive SyncCheck technology (first implemented in the Hammerfall) enables an easy
to use check and display of the current clock status. Input Status indicates whether there is a
valid signal (Lock, No Lock) for each input (Word Clock, ADAT, SPDIF and LTC), or if there is a
valid and synchronous signal (Sync). In the field Clock Mode the clock reference is shown (Cur-
rent…). See chapter 35.1.
In practice, SyncCheck provides
the user with an easy way of
checking whether all digital devices
connected to the system are
properly configured. With
SyncCheck, finally anyone can
master this common source of
error, previously one of the most
complex issues in the digital studio
world.
Note on SPDIF and Word
: Thanks
to its lightning fast SteadyClock
PLL the Fireface UC is not only
capable of handling standard
frequencies, but also any sample
rate between 28 and 200 kHz. For
varispeed operation the word clock
input is the preferred source.
