X-Video Operating Modes
Once the X-Video card has been installed, new CLOCK SOURCE selections become available on Big Ben; these
selections configure the X-Video card into one of three operating modes: Master, Slave and Standalone.
Master – In Master mode, the X-Video card generates the reference for all Big Ben's outputs as well as the three X-
Video card's outputs; the X-Video output format may be set to NTSC, PAL or B&W (black & white). Signal present at
the X-Video IN BNC is ignored. To configure the X-Video card to operate in Master mode, follow these steps:
1
Scroll through Big Ben's CLOCK SOURCE selections until both INT and VIDEO are lit.
2
Press the NEXT button until the sample rate flashes, and select the desired sample rate.
3
Press the NEXT button again until one of the three video formats flashes (NTSC, PAL, B&W), and
select the desired X-Video output format.
Slave – In Slave mode, Big Ben is locked to the video reference signal present at the X-Video IN BNC. To configure
the X-Video in Slave mode, scroll through Big Ben's CLOCK SOURCE selections until VIDEO is lit; the video format is
automatically detected as being either NTSC, PAL or B&W (black & white) format.
Standalone- When Big Ben Clock Source is set to any setting besides INT VIDEO or VIDEO, the X-Video card will ac-
cept a video input and regenerate it to the 3 video outputs, but with no clock synchronization with the selected Big Ben
CLOCK SOURCE. Thus, the X-Video card acts as an asynchronous distribution amplifier.
