Linear Timecode (LTC) is a form of SMPTE timecode encoded into an audio signal. The Hog 4 OS can listen to LTC by inputting the LTC signal to a USB LTC widget attached to a DP8000.
To bring LTC into the system using a DMX Processor 8000:
Connect an external USB LTC widget to one of the USB ports on the rear panel of the DMX Processor 8000 (up to 8 USB LTC widgets are supported on the DP8000; each LTC input is mapped to an "Index")
Connect the LTC source to the LTC widget using a balanced 3-pin XLR connector
Setup → Network : opens the Network window.
In the network window select the DP8000 that you connected the LTC Widget to
Settings : opens the Settings window.
In the Timecode Widgets pane, use the drop down menu to map the attached LTC widget to an index.
