3.4 NTSC Standard

This parameter selects the NTSC video standard.

4.1 Analog Audio Std

This parameter sets the analog audio input and output level of the FS1 with
reference to full scale digital, from consumer levels (+12 dBu) all the way to
professional (+24 dBu).

Note:

Audio levels are discussed at the end of Chapter 3 (FS1 Audio Level Choices—

Pro or Consumer).

4.2 Audio Delay (mS)

This parameter allows you to adjust the delay to compensate for video timing issues
(delay/latency). Pressing the Adjust buttons changes the delay from -16 to 256 ms
(the default is zero delay).

Note:

If parameter 4.5 Audio Follow Video is set to On, then the Audio Delay

selection is independently kept for each separate input: SDI 1, SDI 2, Composite, S-
Video
, and Component. If Audio Follow Video is set to Off, then another Audio Delay
selection is used.
