JumpStart LTC

JumpStart LTC generates Longitudinal Time Code to provide a convenient interface for setting dedicated timecode devices.



Many timecode devices, as robust as they are, often have no way to manually set the time – and if they do, it usually involves pesky dip switches or something similar. Some start at Hour 0 each time they are powered up, with no way to resume a previous timecode.

But with JumpStart LTC you can quickly set time code and userbits!

Plug an 1/8" headphone cable into your iPhone or iPod touch and the other end into the "TimeCode In" of your timecode device (with proper connector as necessary). Press "Start" or "Time of Day," and adjust the volume. Your device will jam sync to JumpStart LTC. Quit JumpStart, detach the cable, and put your iPhone or iPod touch away.

Seconds after launch you are ready to roll sound! Easier than JumpStarting your car!
