Look at all those pretty lights! The timecode input on the 552 sound mixer really is a fantastic addition to a location mixer. Set it up in the menu and the solid blue light lets you know that timecode is being received, the light flashes if timecode is not present. The built in recorder can be set to turn when running timecode is detected and stamps the start of the file with the appropriate time code. This makes it the perfect system for backing up when using wireless links to camera, making it possible to use record run timecode where previously you might have used time of day, a separate recorder and lock-it boxes. If you only need two tracks of audio this is perfect. 

I’m currently trying out a timecode radio link system which seems to be working very well, turning the recorder every time the camera runs. It’s a back up to for sound going to camera on a VHF radio link so we will see how it goes. An update to the system is due in the new year. However there are various systems around that do a similar thing. Check the frequencies they use though as they are notorious for jamming the signal from nearby car key fobs!
