The XLS Series of power amplifi ers from
Crown represents a new era in affordable,
quality power amplifi cation. The line consists
of three models in a uniform, rugged
chassis, incorporating the best of tried-and-

they are to provide the many years of reliable
service for which they were designed.
In addition, XLS Series amplifi ers include a
number of features which require some expla-

mum advantage.
Please take the time to study this manual so

from your amplifi er.
