erwise, they will apply only to output board zero in chassis zero.

To enable V-fade in the Auto mode, set S28-7 and S28-8 both to OFF. In this
case, one of the two Video References must be selected on S28 5-6 (as just
described above).
To disable V-fade, set S28-7 to ON. In this case, the position of S28-8 doesn’t
matter.

ommended.
