External Sync (MAV Plus Video Models)

The MAV Plus switcher switches between inputs during the vertical interval period, resulting in glitch-free video switching. The MAV switcher can use an external signal to synchronize switching during the vertical interval. Without the external sync locking feature, switching between inputs can result in a brief rolling (sync loss) or a brief change in the picture size.

KExt(ernal) Sync connector — Connect an external sync signal to this BNC connection for genlocking the video signal in broadcast or other sync-critical applications.

Figure 25 shows a basic external sync configuration. The Ext Sync connector receives the timing signal. A tee connector on the connector allows the signal to be passed on to another video device, if required. Terminate the tee connector if desired.
