System Overview
The Standard Model 4000 system consists of a Signal Processor Frame, a Frame
Power Supply, a Control Panel and interconnecting cables.
Signal Processor Frame
The Signal Processor frame houses the video and control circuitry for the Model
4000. Frame modules mount in four upper and lower “bays” in the front and back
of the frame.
NOTE:
There are two versions of Model 4000 Signal Processor Frames covered in this
manual; frames shipped before January, 1996 for all model switchers (Matrix 094800-00)
and those modified for the Model 4000-3 (Matrix 094803-00). The matrix number is
labeled on the top left rear of each frame. Any differences between the frames will be
explained in the text for clarity.
Power Distribution
The Model 4000 Signal Processor Frame has a separate power supply
(2 supplies if the optional Redundant Power Supply is installed) which mounts
directly below the Signal Processor frame. Installation and setup of the power
supplies is described in detail in Section 2 - Installation. Replacement and
maintenance of the power supplies is described in Section 4 - Maintenance.
