Within the Device-Tab you can change the Fallback frame count and the LTC Audio Device.
Device Settings and Device Name can only be changed, when all Channels are disabled.
By default, the Device port is 5000.
The Fallback frame count setting is used for fallback scenarios, where the just:in mac channel buffers the amount of frames (=fallback frame count), before switching to the fallback destination or before stopping the recording. We recommend a value between 100-150.
The LTC Audio Device setting can be used for selecting an Audio In Device, like an USB audio in adapter to sync all channels to a LTC source.
