Effects Send Modules (064809)
There are two Effects Send Modules in the Model 4000. Both of which receive video
and key signals from the Mixer Interface Modules.
Each Effects Send Module can send two keys and two video signals (key fill) onto
aux buses. The aux buses can then send the video and key to a DVE. The DVE will
then return the modified signals back through the Crosspoint Module to the same
aux bus. The aux bus will route the video and key signals back to the Effects Send
Module which will send the signals back to the Mixer Interface Module.
The Effects Send Modules will encode, decode, shape, and unshape the video as
necessary.
Effects Send Module 1 in slot B 9 (Matrix 094800-00) or B12 (Matrix 094803-00) r
routes the video and key signals out Aux 1 and 2. Effects Send Module 2 in slot B
11 (or B13) routes the video and key signals out Aux 3 and 4.
Inputs:
There are two sets of input signals to the Effects Send Module:
■
The keys and their associated video that are to be “sent.” These signals come
from the Mixer Interface Modules. The input signals from the Mixer Interface
Modules are sent to the Effects Send Modules. These inputs are sent out on the
aux bus(es) to a DVE
■
The other inputs are the same signals after they have been modified by the
DVE and returned via the aux bus
Outputs:
There are two groups of outputs for the Effects Send Module:
■
The output signals to the Mixer Interface Module. These signals come from the
DVE via the aux buses
■
The aux bus signals to the DVE. These signals come from the Mixer Interface
Module
Processors Used:
■
Both modules use the HOS processor
