PULSE 4X300

The Pulse Series amplifiers are high per- formance professional power amplifiers 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.

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.

Features

•Switch Mode Power Supply delivers great performance without the weight.

•Microprocessor supervision of power sup- plies provides overall system protection.

•Accurate front-panel indicators and level controls.

•Choice of balanced XLR and ¼-inch phone inputs.

•Choice of Speakon® and/or binding post outputs.

•Four-channel operation for increased system flexibility.

•All this performance and reliability in only 2 rack spaces.

At Crown, sonic performance is always in the forefront of our minds. Like all Crown amps, Pulse Series amplifiers have undergone rigor- ous testing in order to ensure their sonic qual- ity and reliability. And every Pulse amplifier is backed by Crown’s unequaled Three-Year, No- Fault, Fully-Transferable Warranty that covers everything.
