in a video combiner, this potential timing discrepancy could cause a
problem.
For this reason, there is a control in the Engineering menu Input
submenu that forces all four Aux bus outputs to be zero timed to each
other, again according to the "latest" source assigned to any Aux bus. In
this submenu, press the
Effects Loop Inputs softkey to access the
Combiner pushknob. Set this control to Combiner On if using a DVE
video combiner; otherwise, leave it set to
Combiner Off
.
STEP 1: You must supply a cable that connects pin 23 (+ GPI 2 Out)

of the A57 GPI A to one or more of the common GPI return
pins (14-21) listed in the following table.
Pin Number Pin Function

NOTE: If you are using two Aux outputs to feed video and
key as a pair to a DVE with key channel, you may need to
connect two front/back switch signals to the 8150, one for
each Aux output (video and key). If you are connecting two
DVEs with key channels, you may need to supply two
front/back switch signals from each DVE.
