Just like a sample clock can be resolved to video, the sample clock can also be resolved to time code
through a simple mathematical relationship. For example, if your HDR24/96 is set to a 48 kHz
Sample Rate and a 30 fps Time Code Frame Rate, the relationship is governed by the following
formula:

(48,000 samples/sec) / (30 frames/second) = 1600 samples/frame

This relationship says that for every 1600 samples that tick on the sample clock, 1 frame ticks on the
time code display. Some digital audio devices will resolve their sample clocks to time code; the
HDR24/96 does not. To make this setup work, an external device like the Aardvark Timesync II is
needed to generate a resolved word clock from LTC.
