I have a HMC 150 and an HMC 40 and was wondering if it is possible to daisy chain (lack of better term) them together so that when the 150 starts to record so does the 40? Any help would be appreciated in setting this up and what else is needed, i.e. cables.
Check you manual- I don't believe so. I'm assuming you're talking about timecode sync. Lots of other ways to do this- like feeding a common audio timecode into one channel on both cameras, to using the same remote control to reset both cameras to a common time of day timecode, etc.
