Clocking Apogee Interfaces
InaSymphonyMobilesystem,therstinterface(connecteddirectlytotheExpressCard)
serves as the clock master to the entire system, and may be set to Internal or External clock
in Apogee’s Maestro application. All remaining interfaces must receive a word clock signal
synchronouswiththerstinterface’sclocksource,whetherInternalorExternal.
WhenaSymphonyMobilesystemisbooted,therstinterfacewillswitchtotheclocksource
speciedinMaestro(InternalorExternal)whiletheremaininginterfaceswillswitchautomatically
to their external word clock source.
The two most common ways to accomplish the necessary word clock connections are depicted
