1600 W Per Channel Class-H Power Amplifier

The transmission qualities of Electro-Voice CP3000S 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 headroomadvantage of a transformer power amplifi er with low weight of a pulsed power supply unit resulting in an improved performance-to-weight ratio. Special attention had been given to high effi ciency 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 amplifi cation 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 effi ciently! 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 fulfi ll 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. The electronically balanced inputs are carried out via XLRtype connectors. Direct-Outs for through connecting the audio signal are also provided via XLRM-type connectors. Input Routing allows selecting DUAL (stereo) or PARALLEL (monaural) operation mode. By means of the separate BRIDGED OUT-connector and a Bridged Modeswitch, switching to “Mono Bridged” operation is truly uncomplicated as well.

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 retrofi tting an internal analogue signal processor board with x-over and fi lter 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 Groundlift switch, which, when needed, 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 2ohms. In Mono-Bridged mode the allowable minimum load is 4ohms.

Compact Precision amplifiers combine outstanding audio performance with the highest-possible reliability and safety to create an ideal high-power solution for touring and rentals. Incorporating an innovative new switchmode power supply into Class-H technology, the CP series delivers clean headroom that is far above stated nominal output. This advanced design also results in improved performance-to-weight ratio for easier touring, reduced waste heat for closer rack spacing, and reduced power consumption for enhanced energy efficiency. A complete set of protection circuitry guards people and equipment against hazardous conditions, and a rigid, robust chassis, built to the highest precision manufacturing standards, ensures dependable operation on even the most grueling tours. With exceptionally clean power and tour-friendly touches that facilitate fast, flexible setup, Compact Precision amplifiers fulfill even the most demanding requirements of pro audio touring.
