Delta-Link MADI HD
TheDelta‐LinkMADIHD,liketheProToolsHDcard,isdesignedtooperateasaClockSlave.
OncethecardandDelta‐LinkMADIHDareconnectedtogether,theycanbeseenasaunit

theʺDigitalandAnalogʺconnectionstootherdevicesprovidedbyProToolsinterfaces.

AlthoughareferencesignalisembeddedinthePrimaryport,theMADIconnectionrequiresa

inputconnector.

DependingonthetypeofunitthatisconnectedtotheMADIport,theSampleRatewillnolonger
changeautomaticallywhenasettingisselectedinthePCorMacsoftware(becausethereisno

ToolssoftwareandonthehardwareconnectedtotheMADIport).
WordClock / FrameClock
TheWordClockinputcantranslateWordClockorFrameClocktotherequiredSampleRate.
