EXTERNAL SYNCHRONIZATION

(VZ-37 and VZ-17 only!)

If Visualizer images are mixed and processed (fade-in, fade-out, mix/wipe) with images from one or more video cameras (or
Visualizers) using a special effect unit without TBC (time base corrector), all units connected must be genlocked.

Genlocking is achieved by supplying the same composite video signal (VBS) or black burst (BB) signal to the Extern Sync
input (=Genlock input) of each unit connected.

In order to genlock the WolfVision Visualizer with another video signal, simply connect this signal to the Sync input (#33) of
the Visualizer where a composite video or a black burst signal can be connected.

With a VZ-37 fine adjustment of color-phase (SC) and H-phase can be made in the unit's on-screen menu.

With a VZ-17 it is necessary to open the unit and adjust the settings with a screwdriver on the camera itself. Please leave
this to a technically experienced person, as there is sensitive and potentially dangerous electronics inside the unit!

Start with H-phase adjustment, followed by rough adjustment of "0/180" followed by fine adjustment with SC.

Genlock operation with a playback signal of a video recorder is only possible if the signal is time base corrected via a TBC
device.

* Parallel GND is the ground for the opto-isolated control inputs. DC GND is the ground for DC + 12 V and also for Video out.
If you want to use DC + 12 V for the control inputs make a connection between DC GND and Parallel GND.
** If the relay is open: Resistor value at least 3k3.
