Circuit Description
This section provides a detailed description of user-serviceable circuits used in the
8382. We do not provide detailed descriptions of the digital circuitry because most
of this is built with surface-mount components that cannot be removed or replaced
with typical tools available in the field. Field repair ordinarily consists of swapping
entire PC boards.
The section starts with an overview of the 8382 system, identifying circuit sections
and describing their purpose. Then each user-repairable section is treated in detail
by first giving an overview of the circuits followed by a component-by-component
description.
The drawing on page 6-25 shows circuit board locations.
Overview
The Control Circuits control the DSP, display, and input/output sections of the 8382
system.
The Input Circuits include the connectors and RF filtering for the analog and digital
audio inputs, the digital sync input, and the circuitry to interface these inputs to the
digital processing.
The Output Circuits include the connectors and RF filtering for the analog and digi-
tal audio outputs, and the circuitry to interface the digital processing to these out-
puts.
The DSP Circuits implement the bypass, test tone, and audio processing using digital
signal processing.
The Power Supply provides power for all 8382 circuit sections.
A block diagram of the DSP signal processing appears on page 6-56.
