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:

Scroll through Big Ben's CLOCK SOURCE selections until both INT and VIDEO are lit.

Press the NEXT button until the sample rate ﬂashes, and select the desired sample rate.

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.
