The HDSP MADI's outstanding clock control allows for a synchronization of the output signal to the word clock's input signal not only at identical sample rates, but also at half, quarter, double and quad sample rates. A playback of 96 kHz can easily be synchronized via a 48 kHz word clock signal.
SyncCheck
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. This is why digi- tal systems always need a single device defined as ‘master’, which sends the same clock signal to all the other (‘slave’) devices.
Remember that a digital system can only have one master! If the HDSP MADI’s clock mode is set to Master, all other devices must be set to Slave.
RME’s exclusive SyncCheck technology (first implemented in the Hammerfall) enables an easy to use check and display of the current clock status. The SyncCheck field indicates whether no signal (No Lock), a valid signal (Lock) or a valid and synchronous signal (Sync) is present at each of the digital clock source inputs. The ‘AutoSync Ref’ display shows the current sync source and the measured frequency.
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.
