Section 3 — Functional Description
Mixer Interface Module (064813) (Slot A8)
The Mixer Interface Module:
■ Routes the video and key signals from Key 1, Key 2, and the A Bus from
both M/Es to the Mix/Wipe Modules and the optional Effects Send
Module
If the Effects Send is not installed, this module simply passes these video
and key signals from the Keyer Modules to the Mix/Wipe Modules. See
Figure 3-5.
When Effects Send is installed, this module acts as a switch. If the switcher
is in normal mode, the Mixer Interface Modules switch the video and keys
from the keyer to the appropriate Mix/Wipe Module. If the switcher is in
the Effects Send mode, the Mixer Interface Module switches the
appropriate video and key signals from the Keyer Module to the Effects
Send Module which sends the signals to the effects generator on aux bus
outputs. Signals from the effects generator are reentered into the switcher
on aux buses. These signals are routed back to the Effects Send Modules
where they are sent to the Mixer Interface Modules and on to the Mix/
Wipe Modules.
