User manual ELECTRO-VOICE CP1800 EDS

[. . . ] Beim Softstart werden die Leistungsausgänge über Relais verzögert zugeschaltet. Zusätzlich verhindert eine Einschaltstrombegrenzung das Ansprechen von Netzsicherungen. Höchste Präzision ist auch in der mechanischen Konstruktion und Verarbeitung gewährleistet. [. . . ] 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 systems 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. Electro-Voice CP-SERIES power amps have been designed to fulfil even the most demanding requirements of touring applications. CP-Series amps are 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 frontto-rear allowing trouble-free operation even in smaller amp-racks. The electronically balanced inputs are carried out via XLR-type 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.
