Electro-Voice’s Precision Series Compact amplifiers offer 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 considerably less heat being generated. This allows the overall size of the amplifier to be reduced substantially without sacrificing performance or reliability.

The audio performance of CP-Series power amps are simply extraordinary. The new switchmode power supply technology, completely designed from scratch and the consistent use of Class-H technology provide extensive headroom far above the stated nominal output and conspicuous reduction in leakage power at the same time.

The flagship of EV’s Precision Series Compact amplifiers is the CP 4000S. With up to 2 x 2100 watts into 2 ohms and 2 x 1500 watts into 4 ohms, it is both the most powerful model in the line and lightweight, at only 19.2 lbs (8.7 kg). The CP 4000S is state-of-the-art for all kinds of applications. It is specifically designed to allow for long-term driving of low loads into subwoofers without stress. The CP 4000S’s reliability and its pleasing, rich sound make it the first choice for all mid- and hi-range speaker cabinets.

The employed switching power supply combines the headroom-advantage of a transformer power amplifier with low weight of a pulsed power supply unit resulting in an improved performance-to-weight ratio. Special attention had been given to high efficiency and interference immunity already in the designing stage with the result that trouble-free operation of CP-Series power amps is possible even in EMV-critical environments.

Being protected against thermal and electrical overload, short circuit and the occurrence of HF/DC at the outputs, Electro-Voice CP-Series power amps fulfill even the most demanding requirements of Pro-Audio touring applications. Back-EMF-Protection eliminates the risk of the output transistors being damaged by electrical energy back-feed. The power outputs are switched via relay with a time delay during soft-start and an inrush current limiter additionally prevents mains fuses from blowing.

The recessed mounted dB-scaled level controls ensure reliable protection against mechanical damage. These particularly precise, secure to operate detent-potentiometers are located on the front panel. CP-Series power amps provide the opportunity for retrofitting an internal analogue signal processor board with x-over and filter functions.

The easily readable LED display provides a quick overview of the power amp’s current operational status. The power outputs CHANNEL A, CHANNEL B and BRIDGED OUT are carried out as extremely durable Speakon-type connectors. Also located on the rear panel is a Ground-lift switch, which helps eliminating ground-noise loops by separating the power amp’s enclosure from the circuit ground. In normal operation, all CP-Series power amps are capable of driving loads as low as 2 ohms. In Mono-Bridged mode the allowable minimum load is 4 ohms.
