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.

The Flagship of the Pre­cision Series Compact amplifiers. It’s the first Precision
Series amplifier utilizing a switch-mode power supply, but
also the first switch-mode amplifier with EV’s Precision
Series sound. With up to 2 x 1600 watts into 2 Ohms and
2 x 1100 watts into 4 Ohms it is not only the most power-

ful in line, but also the lightest model with only 8,15 kg
(17.96 lbs). The CP3000S is state-of-the art for all kinds
applications. It’s specifically designed to allow for long­term driving of low loads with subwoofers without stress.
It’s reliability coupled with it’s pleasing, rich sound makes
it the first choice for all mid and hi speaker cabinets.

With up to 2 x 1100 watts
into 2 Ohms and 2 x 800 watts into 4 Ohms the
CP2200 is not only a perfect complement to many
fullrange speaker cabinets, but also mid- and hi-

frequency components in larger concert-sound sys­tems. The CP2200 utilizes a conventional trans­former power supply, but still weights only 16 kilo­gramms (35.2 lbs).

Supplies up to 2 x 900 watts
into 2 Ohms and 2 x 600 watts into 4 Ohms. Dedi­cated for smaller size full range speaker systems and

hi-frequency components in multiway systems. The
CP1800 utilizes a conventional transformer power
supply.

With up to 2 x 600 watts
into 2 Ohms and 2 x 400 watts into 4 Ohms dedicated
for small fullrange cabinets and individual hi-frequency

components in multiway systems. The CP1200 utilizes
a conventional transformer power supply.
