TE C H N I CAL S PE C I F I CATI O N S Pulse Series Power Ratings Pulse 4x300 Into 8 Ohms Into 4 Ohms Into 2 Ohms 170W 300W 330W Cooler, Lighter, Stronger The Pulse Series combines state-of-the-art switched mode power supplies to not only reduce amplifier weight by as much as 70% compared to conventional amps, but also to provide solid, consistent performance at all power levels. Occupying just 2U of rack space, Pulse uses massive heatsinks and front-venting fans to keep the electronics really cool, plus a built-in microprocessor which continually monitors all the protection aspects of Pulse - these factors all dramatically enhance reliability. Pulse amplifiers will perform for longer periods than conventional amplifiers at high output levels. The combination of the switched mode PSU and a rugged steel chassis means inherent strength.
