Introduction
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.
