This is exactly the point of the NADAC dedicated output of the CLOCK (left most connector). This output provides a frequency that fits for any sampling rate used by NADAC and doesn’t require the CLOCK to be adjusted accordingly.
The CLOCK display shows its internal sampling rate setting, while NADAC display shows its internal SR setting. They can be different, but the special CLOCK output for NADAC allows for a perfect lock anyhow.
Does the MERGING+CLOCK sampling rate
...
follow the MERGING+NADAC / MERGING+PLAYER sampling rate ?
No, it is independent. Again, the special CLOCK output for NADAC allows for a perfect synchronization, without the need to adjust any sampling rate.
...
When listening to an AES or SPDIF source, is the MERGING+CLOCK synchronization used ?
No, to avoid any glitch drift or synchronization error, the AES or SPDIF source is automatically used to synchronize your MERGING+NADAC/MERGING+PLAYER.
In such case, connect the MERGING+CLOCK to your AES or SPDIF source (and set such device to use the Clock synchronization).
And even if your AES or SPDIF source has no possibility to synchronize on an external WC, you may still listen to this source without any glitch.
