Quattrocanali está diseñado para funcionar con baja impedancia (desde 2 Ω) y con líneas distribuidas de 70 V / 100 V: cualquier carga de salida de impedancia mezclada puede ser realizada. Este amplificador también puede ser usado en aplicaciones cruciales, tales como sistemas de alarma de incendio, gracias a la fuente de potencia diseñada inteligentemente que permite operación confiable inclusive cuando es conectada a un sistema de alimentación ininterrumpida. Los servicios de MyPowersoft están disponibles para este producto. Fuente de Potencia Fuente Universal Conmutable con tolerancia de hasta 400VAC a la entrada con Factor Corrector de Potencia (PFC) La limitación de consumo de corriente inicial en AC remueve la necesidad de costosos secuenciadores de encendido Cable de Ac desmontable con clavija IEC C19/22. 2 (16A para UE, 20 A para USA) Protecciones Diseño de circuito completamente protegido en: Protección de AC: La Fuente de alimentación se apaga cuando el voltaje de operación está fuera del rango de operación Limitador de recorte: previene que ondas cuadradas alcancen los parlantes manteniendo la potencia pico de salida Protección en DC: protege contra señales infra sónic

Características
- Powersoft legendary universal switch mode power supply up to 400VAC tolerant with Power Factor Correction
- Low Inrush Limiting reduces AC inrush current, removing the need for expensive power sequencers
- Detachable AC mains cable with IEC C19/22.2 (16A for EU, 20 A for USA) socket
- Ac protection: shut down power supply when AC mains voltage is outside 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, by reducing maximum output
- Thermal protection: output stages operating temperature up to 80 °C (176 °F)
- Temperature controlled continuous variable speed fan, front to back airflow
- Temperature forecast with LCD traced historical behavior
- Fixed frequency switch-mode output stage for high grade sound accuracy
