1 Welcome
The Xs Series of power amplifiers from Crown
®
represents a new era in affordable, quality
power amplification. The line consists of five
models: four 2-channel units and one 4-chan-
nel unit, each in a uniform, rugged chassis. The
Xs Series incorporates the best of tried-and-
true design principles and innovative features.
Modern power amplifiers are sophisticated
pieces of engineering capable of producing
extremely high power levels. They must be
treated with respect and correctly installed if
they are to provide the many years of reliable
service for which they were designed.
In addition, Xs Series amplifiers include a
number of features which require some expla-
nation before they can be used to their maxi-
mum advantage.
Please take the time to study this manual so
that you can obtain the best possible service
from your amplifier.
