Alternativamente el M20D puede manejar líneas de voltaje constante de 70V directamente, donde se requieren múltiples altoparlantes. La máxima eficiencia garantiza un mínimo de consumo de corriente, disipación de calor y consumo de energía, lo que resulta en productos "verdes", ahorrando al usuario una cantidad sustancial de dinero en el tiempo. Fuente de alimentación Avanzada Tecnología de fuente de alimentación conmutable para un alto desempeño y un tamaño compacto Etapa de salida con frecuencia fija de conmutación Filtro de Salida Patentado para cancelar el ripple en la red eléctrica Protecciones Diseño de circuitos completamente protegidos con: Protección de CA: apaga la fuente de alimentación cuando la tensión de alimentación de CA está fuera del rango de operación Limitador de recorte: previene que formas de onda severamente recortadas alcancen los altavoces, manteniendo la potencia de pico completa Protección contra DC: protege la salida contra señales infra sónicas Protecciones a VHF: protege los parlantes contra señales no audibles, fuertes, no musicales de alta frecuencia Protección contra cortocircuito: protege el amplificador contra cortocircuitos u otros eventos estre

Características
- Advanced switch-mode power supply technology for high performance and compact size
- Fixed frequency switch mode output
- Patented output filter with ripple cancellation network
- Ac protection: shut down power supply when AC mains voltage is outside the operating range
- Clip limiter: prevents severely clipped waveforms from reaching loudspeakers, while still maintaining full peak power output
- DC protection: protects against infrasonic signal at the outputs
- VHF protections: protects the loudspeakers against non-audible, strong, non-musical high-frequency signals
- Short circuit protection: protects the amplifier from short circuit or other stressful events for the output circuits with automatic protection reset
- Long term limiter: protects the loudspeaker against steady long term RMS (non-audio) signals reducing maximum output
