5.2 Getting to Know Your SG-7 Sync Transcoder
The KRAMER
SG-7
Universal Sync Transcoder interfaces between the widely used professional video
sync formats - Composite sync, Horizontal sync, Vertical sync - Analog and TTL levels. In many video
studios and professional applications there is a need to convert from one format to the other, and the
KRAMER
SG-7
is the perfect choice - as it operates simultaneously in all directions.
Front/Rear panel features of the SG-7 are described in Figure 4 and Table 3.
NOTE
