Connecting Genlock
Genlock Connections — Internally Generated Reference Signals
The CONTROL Center contains an internal Black Burst generator in the Switcher Unit. Black
Burst signals are output to 8 BNC connectors on the back panel of the Switcher. Devices
connected to any of the Black Burst outputs can be synchronized (genlocked) to the internally-
generated reference signal.
Connecting Sync Signals To CameraMan Cameras:
1. Using high-quality video coaxial cable (75 ohm), terminated with BNC connectors, connect
the genlock input on each of the CameraMan cameras to one of the Black Burst outputs
on the back panel of the Switcher.
2. If necessary, use the Control Unit to adjust the Horizontal (H) Phase and Sub-Carrier (SC)
Phase of each camera to compensate for cable distance and other timing differences in the
cameras (refer to page 40 for details).
Connecting Sync Signals To Other Video Sources:
1. Using high-quality video coaxial cable (75 ohm), terminated with BNC connectors, connect
the genlock input on each of the video sources to one of the Black Burst outputs on the
back panel of the Switcher.
2. If necessary, refer to the Owner’s Manual for the device to which you are connecting to
make timing adjustments.
Genlock Connections — External Reference Signals
If an external reference signal is connected to the Switcher unit, the internal Black Burst
generator will automatically use this signal as its reference. The adjustments and indicators on
the front panel of the Switcher are used for making minor adjustments to the sync signal.
External Reference (Loop Thru) Input
When an external genlock source is connected to the Control Center Switcher it can be
connected to either of the External Reference (Loop Thru) BNC connectors on the rear panel. If
the loop thru capability is not going to be used (i.e. connecting another genlockable device to
the remaining BNC) a 75 Ohm terminator must be connected to the remaining BNC. The inputs
accept either Black Burst or video but the video content must not extend below -20 IRE.
Connect up to eight cameras or
other video sources to Black Burst
outputs.
