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.
