he Pulse Series amplifiers are high per-
formance professional power amplifiers
T
capable of delivering major power output
from a new generation of switched mode power
supplies. All Pulse Series amplifiers 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 amplifier is always operating correctly
thereby protecting both the amplifier and your
speakers from failure.

Crown’s Three-Year, No-Fault, Fully Transferable Warranty
Crown offers a Three-Year, No-Fault, Fully Transferable Warranty for every new Crown ampli-
fier—an unsurpassed industry standard. With this unprecedented No-Fault protection, your new
Crown amplifier is warranted to meet or exceed original specifications for the first three years of
ownership. During this time, if your amplifier fails, or does not perform to original specifications,
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 amplifier.
