Audio Cable Types: Timecode Audio Cable Types

There are many different Audio Cable Types that you may need for sound work. Lets take a look at the different types of timecode connectors you may need for connecting / jamming timecode to a camera or other device.

Most professional cameras used for filming have only 3 audio cable types. They are a 4pin Lemo / 5pin Lemo and BNC. Similar to cameras most of the professional sound mixer / recorders send or receive timecode via 5pin Lemo or BNC.

There are other ways of sending timecode so it is recorded onto an audio track that can be registered in post production video editing software. This usually requires different audio cable types to get timecode from your device to a wireless radio link or a hard-line straight into camera. This is LTC which stands for Linear (or Longitudinal) Timecode.

LTC is not the professional way to use timecode as devices without professional clock crystals will drift in the edit. I and many others advise instead sending an audio feed to camera to match your mix and then editors can use syncing software like PluralEyes more effectively to sync rushes.

Audio Cable Types: BNC / Lemo

This is going to be your most popular cable for timecode when it comes to Sony / Canon and Panasonic cameras. BNC cables are very reliable and easily secured using a locking mechanism. I personally go out from my Sound Devices 664 via Lemo 5pin to a BNC connector that then can be extended with another BNC cable and different mounts can be attached at the other end.

My Workflow for different cameras:

Alexa / Red One Cameras 664 > Lemo 5pin > BNC > BNC Female Coupler > BNC extension > BNC Female Coupler > BNC > Lemo 5pin

Red Epic / Scarlet / Dragon 664 > Lemo 5pin > BNC > BNC Female Coupler > BNC extension > BNC Female Coupler > BNC > Lemo 4pin

Other Cameras Using BNC connections (Sony F65/F55) 664 > Lemo 5pin > BNC > BNC Female Coupler > BNC extension

As you can see I am then able to save money on multiple specific cables and combine uses for them to connect to all cameras. The end sections can be left in the camera and I can then connect to the BNC that is free from messing with the camera.
