El Yamaha PA2120 es el amplificador de potencia comercial de 2 canales de la serie MA\/PA de Yamaha, dise\u00f1ado para expandir zonas de cobertura en instalaciones comerciales cuando se combina con el mixer amplificador MA2120, o para funcionar como amplificador de potencia independiente en instalaciones de menor escala.<\/p>\n

A diferencia del MA2120 (que incorpora mezclador, entradas de micr\u00f3fono y DSP), el PA2120 es exclusivamente un amplificador de potencia: recibe se\u00f1al de l\u00ednea y la amplifica para los parlantes. Su amplificador Clase D ofrece m\u00e1xima eficiencia energ\u00e9tica sin ventiladores, operaci\u00f3n silenciosa y alta confiabilidad.<\/p>\n

Soporta sistemas Lo-Z (baja impedancia) de 3\u03a9\/4\u03a9\/8\u03a9 y sistemas Hi-Z (alta impedancia) de 70V\/100V sin transformadores adicionales. El control remoto de volumen es posible mediante paneles DCP opcionales de Yamaha. La funci\u00f3n de auto standby activa el modo de espera despu\u00e9s de 25 minutos sin se\u00f1al.<\/p>\n

EQ optimizado para parlantes Yamaha VXC\/VXS Series, HPF integrado y LPF seleccionable.<\/p>\n
