This manual contains service information on Crown
power amplifiers. It is designed to be used in conjunc-
tion with the applicable Owner's Manual. However,
some important information is duplicated in this Ser-
vice Manual in case the Owner's Manual is not readily
available.
NOTE: THE INFORMATION IN THIS MANUAL IS INTENDED
FOR USE BY AN EXPERIENCED TECHNICIAN ONLY!
SCOPE
This Service Manual includes several sections. These
sections include Parts Ordering, Specifications, Volt-
age Conversion, Circuit Theory, Factory Test Proce-
dures, Mechanical Parts Lists, and Module Parts Lists.
Schematics are attached. Note that component parts
with circuit board comprise a complete module. Mod-
ule part numbers are always associated with a spe-
cific circuit board, although an unpopulated circuit
board may be built up with different parts to create
different modules. Note that Crown does not sell blank
(unpopulated) circuit boards.
Each of the compact audio power amplifiers are
designed for professional or commercial use. Provid-
ing high power amplification from 20Hz to 20KHz with
minimum distortion, they feature balanced inputs with
bridged and parallel monophonic capability. Specific
features vary depending on model family.
WARRANTY
Each Owner's Manual contains basic policies as re-
lated to the customer. In addition it should be stated
that this service documentation is meant to be used
only by properly trained service personnel. Because
most Crown products carry a 3 Year Full Warranty
(including round trip shipping within the United States),
all warranty service should be referred to the Crown

Center or obtain instructions for receiving Crown Fac-
tory Service please contact the Crown Technical Sup-
