The SMPTE LTC Reader reads a Linear Timecode (LTC) in an audio signal, per the SMPTE 12M specification. The LTC Reader gives you readouts of the Hours, Minutes, Seconds, and Frames per second. There is an LED to indicate if there are any dropped frames, and a user set offset.
Use the Control Pins connected to a Control Script component with an appropriate Lua script to trigger actions within Q-SYS at a specific point in the audio file containing a Timecode, or at a specific point generated by the SMPTE LTC Generator.

---|---|---|
Hours |
Displays the number of elapsed hours. |
0 - 23 |
Minutes |
Displays the number of elapsed minutes. |

Drop Frame |
The indicator illuminates to indicate Drop Frame mode. |
N/A |
Offset |
The frame offset is added to the decoded time to compensate for the fact that the timecode lags the current frame by one frame. Add 1 frame to compensate. You would add more frames to compensate for the time it takes Q-SYS to make any change(s) required by the Lua script. |
