The SCore Ext. Sync card acts as a connector panel for audio clock syn-
chronization inputs and outputs. Three inputs (VIDEO IN, WCLK IN, and AES
SYNC IN) can be used; their signals are sent to the SCore Live sync bus on the
backplane. While the video sync is separated on the card, the other signals
are just driven onto the bus. A green LED indicates that the applied external
sync is used by the system. The system clocks can be used from the WCLK
OUT and AES 3x OUT outputs.
Important If the system is using MADI links, the deviation of the external sync signal
from the nominal clock frequency must not exceed ±100 ppm. If no MADI
links are used, a deviation of ±2500 ppm is tolerated.
