8.4 Settings Dialog - LTC 
The Fireface UC can extract position information as APP (ASIO Positioning Protocol) from 
Timecode (LTC, SMPTE) received at the analog input 4. 
A detected Timecode is shown as time information in the LTC In field. The analog input signal 
needs a specific level: slowly reduce the level until the display stumbles or completely fails. 
Then increase the level by 10 dB. 
The field Input State will show further details of the Timecode. 
Basically Timecode can also be used as clock source. However, the calculation of the position 
information is less precise then. Recommended is a clocking of the Fireface UC with a clock 
signal (for example Word) directly from the device that sends the Timecode.
