Preview Mixer Module
The Preview Mixer Module and all the submodules on the module are
identical to the Program Mixer Module.
Output Modules
The Output Modules (Figure 3-20) have two functions. They combine the
video and the video clock, and they convert the video from the TTL internal
signal to the ECL digital video on the output. The Serial Output Module
also converts from the parallel internal signals to the serial video output.
