Electro-Voice CP4000S 2100W Per Channel Class-H Power Amplifier

The power amplification stages of the Electro-Voice CP4000S follow Class-H technology design, i.e. the power amp provides extremely fast, signal dependent operating voltage switching, which, at the time needed, results in doubling the regular supply voltage. Compared to Class-AB power amps, Class-H power amps generate by far less leakage power at identical output. Consequently, reduced leakage power or dissipation is synonymous to less waste heat. In other words: energy is used more efficiently! As a result, installing Class-H power amps within rack shelf systems or cabinets is possible with less space between appliances. In addition to that and despite offering identical output, power consumption is a lot less than in Class-AB operation.

The transmission qualities of CP-Series power amps are simply extraordinary. The new switching 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 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.
