13. reason for this lies in the often technically inadequate implementation of MIDI Time Code causing MIC to be saddled with high jitter from extemal sources It is impossible to pass on a stable jitter free Word Clock from such an MTC signal However as it is sometimes necessary to perform this conversion to continue with a production begun in semi professional circumstances TimeMachine generates the clean Word Clock necessary for sonic quality by taking an average value from the incoming MIC if the jitter in the incoming MIC were allowed to affect the Word Clock the connected digital devices would all have their audio quality compromised by locking to such a reference clock Settings TCIN MTC CL MTC Connections MIDI or COM Po Word Clock Super Clock AES EBU S PDIF ext MTC in Contents If you should find yourself in such a situation there is sometimes this Glo nte nts better way to synchronise As long as your MTC source eg a stand alone Hard Disk Recorder with a digital input can be externally synchronised you should switch the Word Clock source of the recorder to digital in having connected it to the AES EBU or S PDIF digital output of the TimeMachine Now use the MIC produced by the recorder as a positional reference so that your entire system follows the external device Settings CL Internal V Sync TCIN MTC Connections Stand alone HDR to a professional system Audio Signals
