3. External SourceAn externally-slaved Cantar stamps the audio files with the same TC as the one running in thevideo camera. This requires a link from the camera to Cantar.Set 'TC Source' to 'Ext. Clock' in the Audio & Timecode Menu.The 'E' Timecode icon will blink in the Timecode area, meaning that Cantar is waiting to beslaved to an external LTC source, e.g. a video camera.Cantar is usually in the Record position before the camera, so it monitors the LEMO-5 forincoming LTC and grabs it when coherent TC is received. That is why the Timecode icon keepsblinking orange indicating a Timecode Jam, until the camera is up to speed.Before closing the audio file, Cantar stamps the TC by using the latest valid Timecode so as toeliminate spurious transmission errors and false camera starts. If there is no external timecodesignal, an 'LTC Not Detected' warning appears.Nevertheless, the external TC is grabbed if it is received before the Take's end.Cantar X339
