CLK multiplier 6
Both S/PDIF outputs, optical and coaxial, receive same clock rate settings.
For the S/PDIF output pair are 3 multiply functions available:
x 1, x 2, x 4
Due to the maximum possible S/PDIF clock frequency of 192.0kHz, the
functions of these multipliers are dependent on the adjusted basis clock.
Example 1
The basis clock runs at 32.0kHz, 44.1kHz or 48.0kHz:
x 1: S/PDIF outputs run at 32.0kHz, 44.1kHz or 48.0kHz
x 2: S/PDIF outputs run at 64.0kHz, 88.2kHz or 96.0kHz
x 4: S/PDIF outputs run at 128.0kHz, 176.4kHz or 192.0kHz
Example 2
The basis clock runs at 88.2kHz or 96.0kHz:
x 1: S/PDIF outputs run at 88.2kHz or 96.0kHz
x 2: S/PDIF outputs run at 176.4kHz or 192.0kHz
x 4: S/PDIF outputs run at 176.4kHz or 192.0kHz
Example 3
The basis clock runs at 176.4kHz or 192.0kHz:
x 1: S/PDIF outputs run at 176.4kHz or 192.0kHz
x 2: S/PDIF outputs run at 176.4kHz or 192.0kHz
x 4: S/PDIF outputs run at 176.4kHz or 192.0kHz
The factory default is set at x 1.
MC-3.1 VIDEO SETTINGS
SD VIDEO
This menu enables you to set the internal standard definition (SD) video
sync reference generator to 3 different video sync signal standards:
1) PAL: 25fps, 625 lines
2) NTSC: 29.97fps, 525 lines
3) NTSC BW: 30fps, 525 lines (black + white)
The video standard settings apply to both video outputs simultanuously.
SD FORMAT
Within this menu, you can choose a specific output format of the previously
set video sync signal standard:
1) B + B:
Black + Burst, this function outputs a SD video composite sync signal with
inserted color bust.
2) COMP:
Composite Sync, this function outputs a SD video composite sync signal
without color bust.
3) CB:
Color Bar, this function outputs a SD video color bar signal.
Video and Audio Signal Relations
MC-3.1 auto-detects integer relationsships between the adjusted video
standard and basis clock rate. This applies especially when PAL is selected
as video reference and the basis clock rate (CLK BASIS) is set to 48.0kHz,
96.0kHz or 192.0kHz. In that case, the AES/EBU and S/PDIF generators use
the video frame to lock the Z-preamble of the AES channel block start,
aligned to AES11-1997/2003 and EBU R83-1996.
