Electro-Voice®is a leading professional audio company
and has over 75 years of experience in the design and
manufacture of loudspeakers and microphones. But
many are not aware that Electro-Voice
®
has also more
than 50 years of expertise in the designing and building
high performance professional power amplifiers as well.
Over the years, an unwavering commitment to be the
benchmark in professional amplifier design has made
Electro-Voice

the “gold standard” of amplification for
stadiums, arenas, theatres, cinemas, discotheques and
clubs all around the globe. Due to their sonic purity and
extreme reliability, EV amplifiers have become established
in top concert sound and professional installation projects
worldwide.
ELECTRO-VOICE®–
WORLD-CLASS POWER AMPLIFIERS
For more than 10 years, EV’s Precision Series Linear
Amplifiers including the flagship P3000, have proven
themselves with their outstanding audio performance
and reliability in many demanding audio applications. In
this tradition we are introducing the new Precision Series
Compact amplifiers, which offer our proven Precision Series
performance and reliability in a new compact, lightweight format. This is made possible by incorporating a
highly efficient Class-H design, which results in substantially less heat being generated. This allows the overall size of
the amplifier to be reduced substantially without sacrificing
performance or reliability.
PRECISION SERIES COMPACT AMPLIFIERS -
HI-EFFICIENCY IN A LIGHT & COMPACT FORMAT
In EV’s Class H design, rather than supplying the voltage
for the maximum output power permanently, the permanent voltage rail is designed to cover the average music
signal. If dynamic peaks require a higher output voltage,
the voltage rail is switched to the maximum. This process
saves nearly 50% of the power consumption in a conventional design and results in a dramatic reduction in heat
output. The real test in a successful Class-H design is to
make the voltage switching totally transparent to the
user. This is where EV’s amplifier engineering excellence
makes the difference over other so-called “Class-H” designs.
The audio performance of the Precision Series Compact
amplifiers speaks for itself. They truly set the new standard
in Class-H amplifiers and meet the expectations we set
the original Precision series models.
HOW IT WORKS - INNOVATIVE ENGINEERING
UNIQUE PERFORMANCE - UNMATCHED RELIABILITY
• Four models ranging from 2 x 600 W to 2 x 1600 W
• Legendary EV’s Precision Series sound
• 30% Dynamic Headroom
• Class H-Design for less heat dissipation
• Very light and compact format
• High precision detent front controls
• Dynamic audio limiter
• Robust construction & reliable design, made in Germany
• Unique protection package including Back-EMF
protection
A conventional amplifier design has nearly double the power consumption and requires
double the power dissipation over EV’s Class-H Design of equivalent output power.
The Precision Series Compact amplifier runs much cooler even under adverse conditions.
The THD of the amplifier is limited to a maximum of 1% for signals up to +21dBu.
Even if overdriven, the amplifier will not create any objectionable “clipping signal
effects” that are so fatal for speaker components.
