PULSE  
2X650  
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.  
Features  
Switch Mode Power Supply delivers great  
performance without the weight.  
Choice of balanced XLR, ¼-inch phone and  
removable barrier block inputs.  
Choice of Speakon® and/or binding post  
outputs.  
Microprocessor supervision of power sup-  
plies provides overall system protection.  
Pulse Series amplifiers are as equally at home  
in critical fixed 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 amplifiers are solid and  
reliable—an amp you can count on.  
All this performance and reliability in only  
2 rack spaces.  
Accurate front-panel indicators and level  
controls.

Crown’s Three-Year, No-Fault, Fully Transferable Warranty  
Crown offers a Three-Year, No-Fault, Fully Transferable Warranty for every new Crown ampli-

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,
