Q:
What is the difference between LTC 0 (fastest), and LTC 4 (smoothest)? I have options for LTC 0, LTC 1, LTC 2, LTC 3, LTC 4 in the pop-up for setting clock reference in the session setup window under SYNC I/O setup.
 
A:
LTC 0 (fastest) Allows the quickest resolving to incoming LTC, but with greater jitter. This is the default setting, and should be used when fast lock ups are critical.LTC 2 (average) Offers a compromise of lock up time and jitter quality.LTC 4 (smoothest) Offers the lowest jitter from LTC resolve, but can take six to ten seconds to achieve full resolve. This setting is most appropriate when loading critical audio from an analog master, where reducing or eliminating jitter is more important than lock speed. Be sure to allow adequate pre-roll before punching in.
