merhkanal für kleine installation
Jeff J, 16.11.2018
Die Endstufe hat einen sehr guten Wirkungsgrad, keine Lüfter!
ist sehr kompakt, und kling auch noch gut. Zusammen mit EVID 4.2 ist alles im grünen Bereich.

Mi elección en amplificadores multicanal para instalaciones
17.12.2015
Se ajusta perfectamente a las necesidades de una instalación fija para un cliente, por todo lo siguiente:
- Controles a la vista, los justos y necesarios, pero ninguno más. En el frontal se encuentran 4 mandos de volumen para sendos canales, y el interruptor general. Además se muestran todos los indicadores luminosos, por cierto, muy claros para clientes finales 'no profesionales'.
- Los ajustes que dependen de la instalación se encuentran en el panel trasero, resguardados de las manos inexpertas del usuario final.
- Muy robusto, tanto mecánicamente (yo lo tengo sujeto con los tornillos de rack, sólo por delante, y no he visto la necesidad de añadirle apoyo en la parte trasera), como a nivel de diseño electrónico (tiene todas las protecciones que se esperan de un buen amplificador, y se observa una circuitería y componentes de calidad).
- El peso no es nada exagerado para sus características, y está equilibrado debido a su diseño simétrico.
- Transformador toroidal, que son los más eficientes y menos 'ruidosos'.
- Está pensado para no generar ruido, y por tanto ser usado en entornos silenciosos como aulas o salas multimedia, y estudios audiovisuales. Por eso no utiliza ventiladores, sólo convección a través de las rejillas y especialmente de los eficientes radiadores laterales. Es muy importante dejar al menos una unidad de rack de espacio encima y otra debajo para su buena ventilación.
- El manual está muy claro, las características técnicas no tratan de 'engañar', sino que explican muy bien a que caso se aplica cada una. Excelente manual.
- Extra fino para su capacidad de potencia y sus cuatro canales. ¡¡Sólo ocupa una unidad de rack!!
- Lo he instalado para que trabaje a 4 Ohm por canal (ocho altavoces de 8 Ohm en total) y va de lujo. Buena calidad de sonido, ni siquiera he conseguido escuchar el ruido de fondo.
- La potencia es suficiente para casi cualquier aplicación tipo aula o sala multimedia, o estudio audiovisual. Pero también es una virtud que no sea exageradamente alta, pues esto evita que los usuarios finales inexpertos quemen altavoces.

Lo recomiendo totalmente, en especial para uso en instalaciones fijas de clientes.

You could sum up the whole idea of a PA power amplifier in a single word - sound. The power amp is a crucial part of a musician’s live sound.
