Kayak — User Manual 43
Mix/Effects (M/E) Stage
The Kayak system M/E actually has four keyers, each handling a fill and a
key signal, and it can accept three background sources (A, B, and Utility).
Providing individual source selection rows for each bus is impractical, as
the panel would become too large. For ease of use, Kayak panels have alter-
nate buses accessed by delegation, using Key and PVW/AUX delegation
via the Miscellaneous Bus selection subpanels.
Utility Bus
Besides the standard A and B background inputs, each Kayak also accepts
two Utility inputs. The Utility buses can be used to select signals for special
purposes, and has no relation to the background buses. For example, a
video signal selected on the Utility bus can be used to feed a custom pattern
into a wipe generator, or create a custom border wash pattern.
Effects Send
Effects Send provides a method of integrating digital effects devices into
the M/E. Effects Send switches the key cut and key fill outputs of the keyer
of the M/E to a digital effects device for manipulation. The manipulated
key cut and key fill outputs are then received and sent directly to the inputs
of the mixer circuits of the M/E. Effects Send allows you to process a key
effect as though the digital effects circuits were located inside the M/E
itself.
On the Kayak system, Effects Send is integrated into the M/E and is an
extension of the keying control system.

If the Kayak system is equipped with the optional Digital Picture Manipu-
lator option, the effects become part of the internal M/E’s mixer.
