If you are in need of an additional audio you can now easily connect a Clip-on Microphone with an audio interface for an iPhone and record it with embedded Timecode with our "Recorder" App. You can also use it without an additional microphone for recording comments (e.g Script/Continuity or documentaries)
How it works:
Download the App in the App Store, open it, select a Tentacle Sync E in Green Mode for receiving Timecode via Bluetooth and connect a microphone like those for example to your iPhone
