be eliminated. A setup using word clock generator will
typically not suffer from this kind of problem due to every
device being slave to the same reference. Therefore there
will not be any chain of devices that potentially could
accumulate phase errors.
ADAT interfaces are typically more sensitive to sub sample
delays or phase offsets than AES interfaces.
