I'm working on a shoot with a C300, 1D-C and 5d. I'm recording to 664, sending audio and TC to C300 hardwire, and sending a mono scratch track to 1D-C and 5d via lectro 401.
C300 and 5d are fine, but 1D-C is failing to record the scratch track. I'm sending it line level (as per 1D-C menu). The level setting menu sees tone but upon playback there is no sound.
We've managed to work around it by keeping the 1D -C close and opening camera mic, but obviously, this won't work all the time. Has anybody experienced similar problems?
