Características de protección 5

Protección encendido/apagado

Al encenderse, el amplificador permanece en modo Protect, con las salidas desconectadas, durante aproximadamente seis segundos mientras el alimentador de potencia se carga y se estabiliza. Mientras los relés de salida están abiertos, los LEDs ACL se iluminan. Cuando se quita la alimentación, las cargas de altavoz se desconectan inmediatamente para que no se escuchen ni ruidos ni pops.

Control de señal AUTORAMP™

En el momento en el que un amplificador de la Serie CC se enciende o sale del modo protect, el circuito AUTORAMP circuit se activa. Mientras los altavoces están desconectados, la circuitería AUTORAMP circuit atenúa totalmente la señal. Después del cierre del relé de salida, la señal sube lenta y gradualmente a su nivel seleccionado. El circuito AUTORAMP de Control de Señal tiene algunas ventajas importantes sobre circuitos convencionales de encendido instantáneo:

1.Si hay una señal presente durante el encendido (o cuando se está saliendo de protect), los altavoces son sacudidos con un repentino chorro de potencia sonora,potencialmente dañino.

2.Debido a que la ganancia es reducida después de que el relé de salida se cierre, los contactos no son arqueados, lo cual extiende su vida útil.
