Amplificador multicanal | 4x900 W RMS @ 4 Ω | Alta y Baja impedancia | Clase D
AURA-4B900 es un amplificador multicanal de alta eficiencia (clase D), 4x900 W RMS @4Ω. Compatible con configuraciones de baja y alta impedancia y con modo dual o puente (@4/8Ω). La Serie AURA está construida con la máxima robustez para ofrecer prestaciones duraderas, con circuitos de alimentación especiales diseñados para optimizar el consumo eléctrico y con sistema de refrigeración por ventilación forzada. La Serie AURA también cuenta con la posibilidad de enlazar canales a la primera entrada seleccionándola en el panel trasero, así como con auto stand-by, protección térmica y contra sobrecargas, PFC y sistema anti-clipping. Además, los mandos de volumen del panel frontal se pueden bloquear mediante interruptores en el panel trasero para mayor seguridad.
