he Pulse Series amplifi ers are high per-
formance professional power amplifi ers
capable of delivering major power output
from a new generation of switched mode power
supplies. All Pulse Series amplifi ers are housed
in the same size 2U cases and feature light,
powerful switching power supplies along with
massive heatsinks and two dual-speed fans.
Microprocessor supervision of the power sup-
plies, protection and thermal systems ensures
that the amplifi er is always operating correctly
thereby protecting both the amplifi er and your
speakers from failure.
Pulse Series amplifi ers are as equally at home
in critical fi xed installations and in demand-
ing, live touring sound environments. Capable
of maintaining excellent performance when
being driven to their limit with real loud-
speaker loads, Pulse amplifi ers are solid and
reliable—an amp you can count on.
At Crown, sonic performance is always in the
forefront of our minds. Like all Crown amps,
Pulse Series amplifi ers have undergone rigor-
ous testing in order to ensure their sonic qual-
ity and reliability. And every Pulse amplifi er is
backed by Crown's unequaled Three-Year, No-
Fault, Fully-Transferable Warranty that covers
everything.

tact the Crown Technical Support Group at
800-342-6939 or 219-294-8200. Also, visit the

Crown's Three-Year, No-Fault, Fully Transferable Warranty
Crown offers a Three-Year, No-Fault, Fully Transferable Warranty for every new Crown ampli-
fi er—an unsurpassed industry standard. With this unprecedented No-Fault protection, your new
Crown amplifi er is warranted to meet or exceed original specifi cations for the fi rst three years of
ownership. During this time, if your amplifi er fails, or does not perform to original specifi cations,
it will be repaired or replaced at our expense. About the only things not covered by this warranty
are those losses normally covered by insurance and those caused by intentional abuse. And the
coverage is transferable, should you sell your amplifi er.
See your authorized Crown dealer for full warranty disclosure and details. For customers outside
of the USA, please contact your authorized Crown distributor for warranty information or call
