Section 1 — System Overview
Physical Description
The switcher consists of three main areas: the Control Panel, the
Signal Processor Frame, and the Frame Power Supply (see s) The
electronic circuitry for the Model 2200 is contained on circuit
boards and modules in the Signal Processor Frame and Control
Panel.
Signal Processor Frame
The Signal Processor Frame is a large rack-mounted unit that
houses the system Controller, Mix/Effect logic and processors,
Input/Output interfaces, and Expansion circuit modules.
In addition to the basic system, a typical system may have several
options such as Chroma Keyers, Secondary Wipe Generators, and
Effects Send. Most options are available as circuit board modules
(or submodules called “mezzanine” boards) that are installed in
the Signal Processor Frame.
Refer to the Model 2200
Installation and Service
manual for a
complete description of the Signal Processor.
A main processor and separate M/E processors reside within the
Signal Processor Frame. Since each M/E has its own processor,
failure of one processor does not disable the entire switcher.
Individual effects can continue to operate independently in a
limited capacity.
