Specially designed for cinema

applications, the DCA Series

Digital Cinema Amplifiers

combine QSC's PowerLight technology and a refined audio structure to provide studio-quality performance with touring-quality reliability. These fan-cooled, 2-RU, amps provide unprecedented power in a strong, compact chassis.

In addition to the five two-channel models, two new full-featured four- channel models offer very compact solutions for multi-channel cinema audio amplification. The four channels of the DCA 1824 and DCA 1644 are arranged so that like the two-channel versions, they can be operated in parallel and bridged mono, pairing Channel 1 with Channel 2, and Channel 3 with Channel 4.

Spécifiquement conçus pour les

applications de cinéma, les

amplificateurs de série DCA pour

cinéma numérique combinent la technologie de circuit d’alimentation à découpage PowerLight de QSC à des circuits audio de haute performance, qui allient la qualité sonore des amplificateurs de studio

àla robustesse des amplificateurs de tournée. Ces amplificateurs sont refroidis par ventilateur, n’occupent que deux espaces verticaux dans les bâtis, et fournissent un niveau de puissance sans précédent dans un châssis robuste et compact.

Aux 5 modèles à deux canaux viennent s'ajouter 2 modèles à 4 canaux qui offrent une solution très compacte pour les installations de cinéma multi-canal. Les quatre canaux des amplificateurs DCA 1824 et DCA 1644 sont arrangés de façon

àce que, comme les amplis 2 canaux, ils puissent être utilisés en mode parallèle ou ponté mono, joignant les canaux 1 et 2, ou les canaux 3 et 4.

Speziell für Kinoanwendung entwickelt,

bietet die DCA- (Digital Cinema

Amplifiers) Serie die PowerLight.

Technik in Verbindung mit

studiotauglicher Tontechnik und

Zuverlässigkeit aus dem harten

Tourneegeschäft. Diese lüftergekühlten

Verstärker im 2 HE-Chassis bieten

unvergleichliche Leistung in einem

äußerst kompankten und robusten

Gehäuse.

Zusätzlich zu den fünf Zweikanal-

Verstärkern eröffnen zwei neue

Vierkanal-Verstärker neue

Möglichkeiten für Mehrkanal-

Kinoverstärkung. Die jeweils vier

Kanäle der DCA-1824 und DCA-

1644 können wie auch die

Zweikanal-Versionen im Parallel-

und Mono-Brückenmodus betrieben

werden, z.B. Kanal 1 mit Kanal 2,

und Kanal 3 mit Kanal 4.

Especialmente diseñados para

aplicaciones en cines, la serie de

amplificadores DCA Series Digital

Cinema Amplifiers combina la tecnologia PowerLight y una estructura de audio que proporciona calidad de estudio con la confiabilidad de sistemas para giras. Estos amplificadores con enfriamiento por ventiladores y que ocupan dos espacios en un rack, ofrecen una increíble potencia en un compacto y resistente armazón.

Además de los cinco modelos de dos canales, tenemos dos nuevos modelos de cuatro canales con características completas, ofreciendo así, soluciones prácticas para la amplificación de canales múltiples de audio en cinemas. Los cuatro canales de los DCA1824 y DCA1644 están dispuestos de la misma forma que en las versiones de dos canales, y pueden operarse en paralelo y en mono puenteado, uniendo el canal 1 con el canal 2, y el 3 con el 4.
