GENLOCK

Generator locking (genlock) is a tri-level signal used to synchronize video and audio systems. Genlock is based
on SMPTE 296M and 274M.
There are two (2) important genlock sync modes:
 Monitor Sync
 Sensor Sync
NOTE: For genlock to function correctly, the cameras must be on the same firmware version, and must be using
the same project time base and sensor frame rate.
MONITOR SYNC
Monitor Sync occurs when a genlock signal is provided that is compatible with the current monitor output
frequency. Monitor Sync is achievable even if the BRAIN is using another form of synchronization to sync the
camera sensor.
1. Connect the desired genlock device to the BRAIN using a 3BNC-to-00 LEMO Sync Cable.
A. Connect the green BNC connector to the genlock device.
B. Connect the 00B LEMO connector to the SYNC port on the BRAIN.
2. Go to Menu > Settings > Display > Monitor Control.
3. On the Monitor tab, select Brain HDSDI from the drop-down menu.
4. Select the desired monitor output frequency from the Frequency drop-down menu.
NOTE: Select Auto to automatically match the HD-SDI output to the current project time base.
Monitor Sync is achieved automatically when a genlock signal is provided that is compatible with the
current monitor output frequency. When Monitor Sync is achieved, the GEN indicator in the Lower Status
Row illuminates green.
