User manual ELECTRO-VOICE CP1200 EDS

[. . . ] Sie ist gegen Überhitzung, Überlast, Kurzschluß sowie Hochfrequenz und Gleichspannung am Ausgang geschützt. Eine Beschädigung der Endtransistoren durch Rückeinspeisung elektrischer Energie wird durch die Back-EMF Schutzschaltung verhindert. [. . . ] Optimised power supply units employing low-leakage toroidal transformers provide extensive headroom far above the stated nominal output. At the same time this contributes to a reduction in weight and power dissipation. The CP 1200 is designed in Class-AB technology, have been designed to fulfil even the most demanding requirements of touring applications. The CP 1200 amp is protected against thermal and electrical overload, short circuit and the occurrence of HF/DC at the outputs. 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. Mechanical construction and workmanship also comply with the highest precision manufacturing standards. The rigid sheet steel chassis even resists the most wearing tour operation. Two three-speed high performance fans (off/slow/fast) guarantee outstanding thermal stability at absolute low running noise. The ventilation is directed front-to-rear allowing trouble-free operation even in smaller amp-racks. The electronically balanced inputs are carried out via XLR-type connectors (female). Direct-Outs for through connecting the audio signal are also provided via XLR-type connectors (male).
