ElectroVoice CP1800 Amplifier
The audio performance of CP power amps are simply extraordinary. Optimised power supply units employing low-leakage toroidal transformers and the consistent use of Class-H technology provide exten-sive headroom far above the stated nominal output. At the same time this contributes to a reduction inweight and power dissipation.The CP-Series is designed in Class-H technology, i.e. the power amp provides extremely fast, signal-dependent operating voltage switching, which results in doubling the regular supply voltage when needed.Compared to Class-AB power amps, Class-H power amps generate by far less power dissipation atidentical output. Consequently, reduced leakage power or dissipation is synonymous to less waste heat– energy is used more efficiently. As a result, installing Class-H power amps within rack shelf systemsis 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.
