Amplifiers

The Precision Series™ (P-Series), EV´s top line of power am-

plifiers, has become a world standard in touring business.

Their extr

eme reliability, high-level sound and durable design

make them the amp of choice for the Rolling Stones´ world

concert tours. A two-year tour is torture for any piece of

touring equipment and EV´s speakers and amplifiers did an

outstanding job, not only fr

om an acoustical point of view.

During the two-year period, only one fuse blew on one of

the amplifiers!

All EV amps are equipped with a unrivalled and complete

protection and safety package for maximum sound perform-

ance. Their technical specifications r

epresent the highest

league of professional power amplifiers. Precision Series™

guarantees, among other things, outstanding transient

response for uncomplicated sonic reproduction of the origi-

nal signal, and extr

emely low dynamic distortion to ensure

excellent sound quality. Q-Series and CPS-Series are based

on Precision Series™.

All EV Amplifiers feature:
