Introduction
The PULSE series of amplifiers are high performance 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 cooling fans. Microprocessor supervision of the power supplies,
protection and thermal systems, ensures that the amplifier is always operating correctly thereby
protecting both the amplifier and your speakers from failure.
We set out to design an amplifier that is as equally at home in live touring sound environments as it is for
installation amplification. We especially wanted to produce amplifiers that are capable of maintaining
excellent performance when being driven to their limit with real loudspeaker loads.
Sonic performance is always in the forefront of our minds and to this end the PULSE series represents the
pinnacle of many years work with professional amplifiers. PULSE amplifiers have impeccable technical
specifications, and extensive listening tests by many people with a wide variety of loudspeakers leads us
to believe that they sound pretty good too!
