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 de-
vices 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.
