Downstream Keyers (Half M/E and DSK Option)
Besides the four standard full-function keyers, an additional four simple
(Linear and Luminance only) Downstream Keyers are available as an
option (as part of the Half M/E and DSK Upgrade). These DSKs can be
coupled to any M/E in the system to operate downstream of that M/E. The
DSKs do not support chroma keys or DPM effects.
