Electro-Voice CP3000S 120V Class-H Power Amplifier (Discontinued)

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.

The power amplification stages of the CP3000S 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.

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.

Mechanical construction and workmanship also comply with the highest precision manufacturing standards. The robust chassis is extremely rigid which makes it especially suitable for wearing touring applications. Two three-speed high performance fans (off/slow/fast) guarantee outstanding thermal stability at absolute low running noise. Front-to-rear ventilation allows trouble-free operation even in smaller amp-racks.
