Inputs:
The inputs to the Mixer Interface Module can be separated into two groups:
■
The first group is all 24 primary video and key buses from the Key Carrier
Modules. If the system is in the normal (not effects send) mode these signals
are passed along to the Mix/Wipe Modules. When the Model 4000 is in the
effects send mode, one or more (up to four) of the keys and their associated
video (key fill) are rerouted to the Effects send Module. The rest of the signals
are still sent directly to the Mix/Wipe Modules.
■
The second group of inputs are the modified key(s) and video(s) being
returned from the Effects Send Modules. These are then sent to the Mix/Wipe
Module. From there the signals are sent to the Output Modules over the same
key or video path they were on before they were sent to the Effects Send
Module.
The input signals are given in
(Matrix 094800-00) and Table 3-5 (Matrix
094803-00) below.
