HD24/96 Technical Reference 72
Sync Sample Clock Pull-down menu to select the source for the sample
clock. Choices are Internal, External word clock
(BNC), or external video (BNC).
Internal operates the HDR24/96 on its internal
clock.
Word Clock (BNC) synchronizes the HDR24/96 to
an external word clock source, for example a digital
console or a clock generator.
When Video is selected for the clock source, the
internal sample clock is synchronized with the
incoming video frame rate to assure that audio
remains in sync with the video.
When using Video as the clock sync source, an
additional pull-down menu appears to select the
video field rate.
Video Field Rate Pull-down menu to select field rate of incoming
video signal. Appears when Video is selected as
Sample Clock source.
